Occult Pulmonary Micrometastases From a Papillary Thyroid Carcinoma Undetectable by Imaging.

Pulmonary metastases from papillary thyroid carcinoma (PTC) are usually detectable by computed tomography (CT) or radioactive iodine (RAI) scanning. Pathologically proven pulmonary micrometastases that are completely undetectable by imaging have rarely been reported. A 39-year-old woman underwent surveillance CT four years after total thyroidectomy for PTC. A solitary right pulmonary nodule, which had been present since before thyroid surgery and had gradually enlarged, was clinically suspected to be metastatic. Wedge resection of the lung revealed the nodule to be a benign hemangioma. However

Multinodule abnormalities of the tracheobronchus: bronchoscopy findings and clinical diagnosis.

BACKGROUND AND AIMS: Bronchoscopy is an important method for diagnosing respiratory disease. Multiple tracheobronchial nodules are rarely reported and their causes remain unclear. OBJECTIVES: The aim of this study was to describe the clinical characteristics of multiple nodule tracheobronchial abnormalities found under bronchoscopy caused by different diseases. METHODS: Eighty-seven patients with multiple tracheobronchial nodules were enrolled in this study. The characteristics of the multinodule lesions and the patient were diagnosed based on the pathology findings in our hospital. Chest co

Pulmonary epitheloid hemangioendothelioma: a peculiar rare tumor of vascular origin.

An extremely rare case of pulmonary epitheloid hemangioendothelioma (PEH), previously known as intravascular bronchoalveolar tumor (IVBAT), in a 38-year-old female is presented. This patient had a history of rheumatoid arthritis and bilateral multiple small pulmonary nodules which progressed over the years. The histopathological diagnosis of PEH was confirmed by immunohistochemical stains. Prognosis of this tumor is very unpredictable. There is no effective treatment for pulmonary epitheloid hemangioendothelioma.

[Pulmonary nocardiosis in an immunocompetent patient with bronchiectasis].

We present a case of pulmonary nocardiosis in an immunocompetent patient with bronchiectasis in the middle lobe and lingula. The radiologic findings were pulmonary nodules, areas of consolidation, and multiple bronchiolar impactions. The patient died and the definitive diagnosis was confirmed at autopsy. Nocardiosis should be taken into account in patients with exacerbation of bronchiectasis.

Who is at risk of lung nodules on low-dose CT in a Western country? A population-based approach.

BACKGROUND: This population-based study aimed to identify the risk factors for lung nodules in a Western European general population. METHODS: We quantified the presence or absence of lung nodules among 12 055 participants of the Dutch population-based ImaLife (Imaging in Lifelines) study (age ≥45 years) who underwent low-dose chest computed tomography. Outcomes included the presence of 1) at least one solid lung nodule (volume ≥30 mm3) and 2) a clinically relevant lung nodule (volume ≥100 mm3). Fully adjusted multivariable logistic regression models were applied overall and stratified by smo

[A case of pulmonary nodules and cysts associated with hypereosinophilia].

A 56-year-old male patient presented with an 18-year history of pulmonary opacities and a 9-year history of hypereosinophilia. The patient was asymptomatic. Bronchoscopy was negative for pathogens. Serial chest radiographs showed stable lung lesions. Nine years ago, an elevated blood eosinophil count [(0.5-1.5)×109/L] was noted. A chest computed tomography (CT) scan showed multiple nodules and cysts in bilateral lungs, which were not investigated further. Two weeks before admission, a follow-up chest CT scan demonstrated slight enlargement and an increase in the number of pulmonary nodules and

Pulmonary light chain deposition disease: a case series and literature review.

BACKGROUND: Light chain deposition disease (LCDD) is a systemic disorder typically characterized by non-amyloid monoclonal immunoglobulin light chain deposition in tissues. LCDD is recognized as a multisystem disease, in which the kidneys and liver are often affected. However, it is rarely encountered as a localized pulmonary disease. This study set out to characterize the clinical manifestations and features of pulmonary light-chain deposition disease (PLCDD) by conducting a retrospective analysis of clinical data obtained from patients, with the aim of improving clinical understanding of PLC

Pulmonary Cryptococcosis Accidentally Detected by 68Ga-Pentixafor PET/CT in a Patient With Multiple Myeloma.

Ga-pentixafor PET/CT in a 66-year-old woman with newly diagnosed multiple myeloma showed extensive disease in bone and bone marrow. After 6 cycles of chemotherapy, the patient was in complete remission but complained of fever and coughing. Follow-up Ga-pentixafor PET/CT showed significantly reduced uptake in bone and bone marrow, consistent with her clinical outcome of myeloma. However, patches, nodules, and ground-grass opacities in bilateral lungs with moderate to intense uptake of Ga-pentixafor were noted. The histopathology of the biopsy for the pulmonary nodule confirmed pulmonary cryptoc

Metastatic pulmonary adenocarcinoma in a llama (Lama glama).

An adult female llama with a comminuted fracture of the left femoral head was necropsied. A firm multinodular mass infiltrated skeletal muscle adjacent to the fracture. Multiple, firm, white nodules were in the pulmonary parenchyma and pleura. A single nodule was in the liver. Microscopically, transition from nonneoplastic bronchiolar epithelium to neoplastic epithelium that formed acinar structures was evident at bronchioloalveolar junctions. A diagnosis of pulmonary adenocarcinoma was made. Similar neoplastic tissue was in the liver and in the perifemoral mass. Immunohistochemically, neoplas

Uniportal VATS right superior lobectomy: management of pulmonary vein variation: a case report.

BACKGROUND: Although there are lots of variations of pulmonary veins including dangerous type that could cause serious complications during surgery, limited information has been reported about these variations. We have experienced an extremely rare anomaly of the right superior pulmonary vein during right superior lobectomy. We used a technique called "non fissure" to manage the right superior pulmonary vein, and the results were satisfactory. CASE PRESENTATION: A 66-year-old woman with lung nodules visited our hospital. Chest computed tomography revealed multiple ground glass nodules in the

(18)F-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography findings are different between invasive and noninvasive pulmonary aspergillosis.

OBJECTIVE: Invasive pulmonary aspergillosis (IPA) is a significant cause of morbidity and mortality especially in immunocompromised patients, and extensive work has been done in the field of diagnostic imaging. The purpose of our study was to evaluate functional metabolic image findings of F-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET)/computed tomography (CT) in the patients with invasive and noninvasive forms of pulmonary aspergillosis (IPA and NIPA, respectively). METHODS: We retrospectively reviewed 24 consecutive patients who had pulmonary aspergillosis among the pat

Teclistamab в случае множественных легочных повреждений в внематочной миломе: первый успешный случай и обзор литературы.

Внешняя болезнь (ЭМД) в миеломе (ММ) связана с агрессивным клиническим поведением и плохим прогнозом, особенно когда речь идет о легочной паренхиме, которая является крайне редким проявлением. Биогенные антитела, направленные против антигена B-клеток (BCMA), такие, как теклистамб, недавно продемонстрировали многообещающую эффективность при сильно обработанном реактивном/охлаждении множественной миеломы (RRMM). Однако данные об их активности у пациентов с внематочным участием лёгких остаются ограниченными. Мы сообщаем о случае 76-year-old Человек с Ига-Ирма, у которого возникли множественные вн

Cutaneous T-cell-rich B-cell lymphoma in a horse.

Cutaneous malignant lymphomas are rare in horses and comprise predominantly T-cell-rich B-cell lymphomas. They are characterized by multiple tumour nodules affecting predominantly female horses with a survival rate of months to years. At the final stage, metastases to regional lymph nodes occur, whereas widespread organ involvement is rarely reported. In this case report, a cutaneous T-cell-rich B-cell lymphoma in a 7-year-old standardbred gelding with metastases is described. Clinically, multiple cutaneous and subcutaneous nodules, enlarged superficial lymph nodes, rapid weight loss, and vent

[Mucosa-associated lymphoid tissue lymphoma in the thymus with multiple amyloid nodules in the both lungs].

Here, we present a case of mucosa-associated lymphoid tissue (MALT) lymphoma in the thymus with multiple amyloid nodules in both lung. A 66-year-old woman was incidentally found to have an abnormal shadow on mass-screening chest roentgenogram. A chest computed tomography (CT) demonstrated a mass of 50 mm in diameter with a smooth margin adjacent to the heart in the anterior mediastinum and multiple small nodules in both lung. As a differential diagnosis, thymic carcinoma with multiple lung metastases was firstly considered from these clinical informations. To make a definite diagnosis, the ope

AI-assisted chest radiograph interpretation enhances diagnostic confidence and standardizes diagnostic accuracy across radiologists: A multi-reader study.

PURPOSE: To evaluate the impact of an artificial intelligence (AI)-assisted computer-aided detection (CAD) system on the diagnostic accuracy and confidence in chest radiograph interpretation among nonthoracic radiologists and radiology residents with varying levels of experience. METHODS: In this retrospective multiple-reader, multiple-case (MRMC) study, 400 chest radiographs (100 each for pulmonary nodules, pleural effusion, pneumothorax, and controls) were independently interpreted by 12 readers (two nonthoracic radiologists, four senior residents, and six junior residents). Readings were c

[Multiple insufficiency fractures (metatarsial, calcaneal and sacral) as the first manifestation of lung adenocarcinoma. A case report and literature review].

Insufficiency fractures, or pathological fractures, are produced after minimal trauma or no prior trauma and normally affect weakened bone. Their presence should be suspected in fractures showing abnormal patterns, when several fractures occur in a short period of time and in those with no apparent or only minimal trauma. On confirmation of an insufficiency fracture, a differential diagnosis should be made between tumoral and metastatic fractures if there is a history of underlying primary malignancy. The epidemiology of lung cancer has changed due to women's adoption of smoking. In women, the

Pulmonary MALT lymphoma: Imaging findings in 18 cases and the associated pathological correlations.

BACKGROUND: Pulmonary MALT lymphoma is a rare disease that is easily misdiagnosed. The objective of this study was to improve the understanding of pulmonary MALT lymphoma for clinicians. METHODS: The computed tomography (CT) scans of 18 patients (13 males and 5 females), aged 41-70 years (mean=55.6 years), with histologically proven pulmonary MALT lymphoma were retrospectively reviewed by two radiologists, and pulmonary imaging findings were described. Correlations between the pulmonary abnormalities and histopathological findings in 13 patients were retrospectively reviewed. RESULTS: Elemen

CT Findings of Pulmonary Metastases from Primary Cardiac Angiosarcoma.

BACKGROUND: Primary cardiac angiosarcoma is a rare malignancy with high predilection to involve surrounding structures such as pulmonary metastases. We analysed the chest computed tomography (CT) imaging features of patients diagnosed with primary cardiac angiosarcoma with pulmonary metastases in this study. METHODS: This study retrospectively reviewed 12 patients with confirmed primary cardiac angiosarcoma, out of which eight (all men) with pulmonary metastasis were included in the analysis. The patients' age ranged from 17 to 74 (mean: 48) years. CT was performed in all patients with unenha

Case report: actinomycosis: multinodular pulmonary involvement.

Previous computed tomography reports of pulmonary actinomycosis most commonly describe single, unilateral parenchymal or pleural masses with or without cavitation. The authors describe a thoracic computed tomograph of histologically proven actinomycosis that revealed multiple, bilateral, small pulmonary parenchymal nodules with an associated liver mass, suggesting hematogenous dissemination to the lungs from the liver via the hepatic veins.

Preoperative localization of lung nodules: a comparative analysis of hookwire and radio-guided procedures.

BACKGROUND: Histological diagnosis of pulmonary nodules requires surgical resection on many occasions. There are multiple localization strategies each with their own benefits and complications. The objective of this study is to compare preoperative lung nodule localization with hookwire and radiotracer injection (radioguided occult lesion localization, ROLL). To compare results, complications, and volume of the sample resected with both techniques. METHODS: Patients undergoing resection of pulmonary nodules with video-assisted thoracoscopy and pre-surgical localization with hookwire or ROLL w
