title: Primary extracranial meningioma of the lower limb.
abstract: This paper is about a primary extracranial meningioma case of a 40-year-old male patient who presented with a complaint of a rapidly growing painless stiff mass located in his left thigh. The magnetic resonance imaging examination revealed that the lesion was well-circumscribed and with isosignal intensity to muscle on T1-weighted images and with a relatively hiperintense on T2-weighted images. The histopathological analysis of the specimens both from the incisional biopsy and the excisional surgery were typical of meningioma showing spindle cell proliferation with a whirling pattern. Although extracranial meningiomas are very rare, it should be considered in the differential diagnosis of a spindle cell neoplasm.
