Positron emission tomography combined with computed tomography with 18F-fluorodeoxyglucose and 18F-сholine in meningeal solitary fibrous tumors: short literature review sample and clinical cases

Solitary fibrous tumors of the cerebral membranes are rare brain tumors. meningeal solitary fibrous tumors often metastasize outside the central nervous system, which significantly reduces the life expectancy of patients, while metastases can appear in a distant period after radical treatment of the primary intracranial tumor. The results of positron emission tomography combined with computed tomography with 18F-fluorodeoxyglucose and 18F-choline in 2 patients with different differentiation of solitary fibrous tumors were analyzed. The presented clinical cases demonstrate that clinical morphological variants of solitary fibrous tumors differ in aggressiveness and clinical course of the disease.
