Value of computed tomography in the evaluation of craniosynostosis.

Forty-seven patients with abnormal cranial shape and the clinical diagnosis of craniosynostosis were assessed by computed tomography (CT). In 13 patients the diagnosis of craniosynostosis was established on the basis of skull radiographs and radionuclide bone scans. Eight out of 13 patients had normal cerebral anatomy demonstrated by CT. In four of the 13 patients CT revealed abnormalities not amenable to surgical correction. The only patient in whom CT scanning influenced therapy presented with elevated intracranial pressure secondary to shunt failure.

The role of computed tomography in pelvic fractures.

Adequate radiologic demonstration of the extent of pelvic fractures facilitates planning of their treatment by the orthopedic surgeon. Traditionally, this evaluation has been by conventional radiology. This report details results of computed tomography (CT) in the evaluation of pelvic fractures in 34 patients. In most cases, CT was able to identify and delineate the extent of fractures, demonstrate displacement of the involved bones, localize bone fragments and characterize joint derangements. Many of these features were better demonstrated at CT compared with conventional radiographs. In part…

Computed tomography of the lesser peritoneal sac.

Computed tomography (CT) was the primary diagnostic modality used in the evaluation of 14 patients with 15 surgically proved lesions of the lesser peritoneal sac. CT accurately localized 14 of the 15 abnormalities to the lesser sac. When combined with clinical information, CT correctly suggested the preoperative diagnosis of 13 of 15 lesions. The lesser sac abnormalities included a variety of pathologic entities: pseudocysts, abscesses, hematomas, a perforated gastric ulcer, a biloma, and a malignant neoplasm. The CT anatomy of the normal and abnormal lesser sac is discussed, with emphasis on …

Computed tomography in the diagnosis of retroperitoneal fibrosis.

We report the findings on computed tomography (CT) in idiopathic and secondary retroperitoneal fibrosis in 7 patients. In all cases CT showed the fibrotic mass, accurately defining its extent and the involvement of adjacent anatomic structures. The densitometric and anatomopathologic aspects were correlated; contrast uptake was less in areas thought to be dense in collagen than it was in areas with more vascular regions of inflammatory change. CT assessed the extent and nature of the fibrotic plaque.

Computerized tomography in the diagnosis of retroperitoneal fibrosis.

We evaluated 4 patients with surgically proved retroperitoneal fibrosis by computerized tomography and ultrasound. Retroperitoneal fibrosis was diagnosed correctly in all 4 patients by computerized tomography but was detected by ultrasound in only 1. On computerized tomography, retroperitoneal fibrosis demonstrated a characteristic soft tissue mass enveloping the abdominal aorta, inferior vena cava and ureters. Computerized tomography was capable of detecting the abnormality with greater reliability than ultrasound, and was far superior in delineating the extent of the process and its relation…

Computed tomography in the evaluation of mediastinal widening.

Computed tomography was employed in 71 patients to assess a widened mediastinum detected on plain chest radiography. In 92% of the patients, CT correctly identified normal variants, sift-tissue density masses or vascular abnormalities as the cause of mediastinal widening. In 8% of the scans, all performed early in our experience, CT diagnosis was indeterminate (4%) or incorrect (4%). In 58% of the cases, a specific and correct CT diagnosis was made, which obviated further and more invasive diagnostic evaluation. CT scanning can differentiate vascular from avascular causes of mediastinal wideni…

Validity of computerized tomography in adrenal diseases.

For diagnosis of adenomas in primary aldosteronism CT proved to be helpful. Although microadenomas have to be ruled out by selective venous sampling from both adrenal glands adenomas down to 8 mm in diameter can be visualized. Scintigraphy does not always permit reliable differentiation of unilateral adenoma from bilateral hyperplasia. -- in endogenous Cushing's syndrome adrenal carcinomas are underlying etiologically in about 10% of the cases. Since carcinomas are detected easily by CT it should be performed in the first place. Whereas adenomas and hyperplasia are easily diagnosed by scintigr

Diagnosis of lipoid pneumonia by computed tomography.

Computed tomography (CT) can establish the diagnosis of lipoid pneumonia in lung masses by detecting fat. In this case report, the diagnosis of lipoid pneumonia was first suggested by CT, supported by a long history of mineral oil ingestion, and confirmed by needle aspiration biopsy of the larger of two lung lesions and specific stains. In the future, the detection of fat in lung masses by CT will warrant intermittent follow-up by routine chest x-ray films. Needle aspiration biopsy or surgery would be needed only if a mass showed signs of growth.

Вычислил томографию в диагнозе болезни Канавана.

Вычисленная томография (CT-сканирование) продемонстрировала симметричное снижение степени уменьшения содержания белой материи в полушариях головного мозга двух детей с макроцефалией и нормальным неврологическим обследованием. Последующее замедление развития привело к биопсии мозга, которая зафиксировала болезнь Канавана (понижение дегенерации мозга, Van Bogaert-Bertrand типа). КТ, полученные от этих пациентов с доказанным заболеванием Канавана, оказались весьма характерными для проведения различия между этим расстройством и болезнью Александра и адренолюкодистрофистрофой (болезнью ребенка). Ск

Computed tomography (CT scan) demonstrated a symmetrical decrease in white matter attenuation of the cerebral hemispheres of two young children with macrocephaly and normal neurological examination. Subsequent developmental delay led to brain biopsy, which documented Canavan's disease (spongy degeneration of the brain, Van Bogaert-Bertrand type). The CT scan…

[Computer tomography of the spleen (author's transl)].

The specialist will expect diagnostic information on the spleen in particular with regard to its size. Well-tried examination methods are available. However, important arguments in favour of computer tomography in special cases are, among others, easy execution, reproducibility, accuracy of presentation, and an examination method which places practically no burden on the patient. In the author's opinion, the significance of CT representation of the spleen is undisputed with regard to radiation planning. The significance of computer tomography for the greater part of diagnostic problems -- tumo…

Carcinoma of the urachus: the role of computed tomography.

Carcinoma of the urachus is a rare entity with poor prognosis. Calcification, a deformed bladder apex, and lateral ureteral displacement have been described as radiographic findings, although radiology has been considered to be of limited value in establishing the diagnosis. Two cases are reported in which computed tomography (CT) contributed to the diagnosis and management. The association of a calcified suprapubic mass on CT together with a history of the passage of blood and mucus per urethra is suggestive of the diagnosis.

Computed tomography in diagnosis of pelvic lipomatosis.

Pelvic lipomatosis is a disease characterized by abnormal deposition of mature adipose tissue within the confines of the pelvis surrounding the bladder, prostate, and rectosigmoid. The presenting symptoms are vague and nonspecific, and it has typical radiologic features. Computed tomography is extremely useful in the differential diagnosis because of its ability to differentiate fatty infiltration from other conditions which can cause elevation and compression of the urinary bladder and sigmoid colon. Computed tomographic confirmation of the presence of fat surrounding the bladder and rectum e…

Computed tomography in the evaluation of a pelvic tumor.

A case of a pelvic tumor evaluated preoperatively by computed tomography (CT) is reported. Conventional radiology suggested pelvic lipomatosis, but CT revealed a solid tumor without fat deposits.

Ultrasonography and computed tomography of carcinoma of the gallbladder.

Ultrasonography and CT have been used to diagnose carcinoma of the gallbladder, since in most patients the diagnosis cannot be made through radiography alone. Ultrasonography was performed on 14 patients and CT on 7. Ultrasonographic findings are classified into four types. Frequently, there are gallstones, dilated bile ducts, or metastatic lesions in the liver or retroperitoneal lymph nodes. The diagnosis was made or suggested by ultrasonography in 84.6% of patients. Findings on CT correlated well with the ultrasonographic features.

[Computerized tomography of the orbita (author's transl)].

Computerized tomography of the orbita is today the most accurate method to determine the causes of exophthalmus. It can detect and localise precisely congenital, inflammatory and neoplastic disease of the orbita and its surroundings. Specific diagnosis is not always possible; it may be attained, if complementary neuroradiological methods are applied. Higher spatial resolution will probably allow to apply computerized tomography also to other, more discrete orbital diseases.

Computed tomography in the diagnosis of adrenal disease.

A series of 63 patients with suspected adrenal disease was evaluated by computed tomography (CT). In 15 additional patients CT diagnosed unsuspected adrenal disease. The CT results were correlated with surgical, postmortem, or compelling clinical data. In those patients with adequate visualization of both adrenals, CT correctly identified all adrenal masses subsequently proven at surgery or postmortem examination. CT accurately predicted the presence or absence of a unilateral adrenal neoplasm in patients with Cushing's syndrome and primary aldosteronism. Unsuspected primary or metastatic neop…
