Best cases from the AFIP - Involuted sclerotic meningioma

A 27-year-old man presented to the emergency department with a 1-year history of intermittent, severe, sharp headache. The pain was usually generalized but on occasion was localized to the left side of the head and was sometimes associated with photophobia and sonophobia. The patient reported experiencing weakness and clumsiness of the left arm over the past year. The results of physical and neurologic examinations were normal. Computed tomography (CT) demonstrated a densely calcified mass, likely a meningioma, over the convexity of the left temporal lobe posteriorly. The clinical impression was that the headaches were related to migraines and not to the mass. The patient subsequently underwent magnetic resonance (MR) imaging, which helped confirm a. densely calcified extraaxial mass.
