Аннотация
RATIONALE: Intracranial solitary fibrous tumor (ISFT) is a rare spindle cell tumor derived from dendritic mesenchymal cells expressing CD34 antigens, which are widely distributed in human connective tissues.
PATIENT CONCERNS: In two case reports, we describe a 61-year-old woman and a 42-year-old man who present with intracranial malignant SFTs. Computed tomography or magnetic resonance imaging of head revealed that the largest size is about 3.3 × 3.0 cm in left occipital part and 4.0 × 3.0 cm in right skull base.
DIAGNOSIS: Postoperative pathological results demonstrated that all of two cases are SFT. Case one: Immunohistochemical examination demonstrated a strong immunoreaction for cluster of differentiation (CD)34, B-cell lymphoma 2 (Bcl-2) and Vimentin (Vim). Case two: The tumor was distinctively positive for Bcl-2, but not for CD34 and Vim.
INTERVENTIONS: One of the two patients recurred 6 years after the first tumor resection. After the recurrence, two gamma knife treatments were given, and another operation was performed about five years later. In one case, only tumor resection was performed.
OUTCOMES: Case one: The postoperative neurological status was substantially improved and regular follow-up examinations for 6 months postsurgery have shown that the patient is currently disease-free. Case two: The patient achieved a good outcome, with no epilepsy or other neurological symptoms experienced on a regular 6-month follow-up. The patient is currently disease free.
LESSONS: Imaging findings can be used to assist the diagnosis. The diagnostic method is pathology, and total surgical resection is the most effective treatment. The main treatment methods were total resection, supplemented by radiotherapy and chemotherapy if necessary.
