Case Reports
[Intracranial inflammatory pseudotumor resected after transcatheter embolization: a case report].
A 63-year-old man presented with an exceptionally rare case of intracranial inflammatory pseudotumor manifesting as speech and gait disturbance. Magnetic resonance imaging showed a left convexity mass with significant peritumoral edema. The mass was attached to the convexity dura and mimicked meningioma. ⋯ Only a small number of IgG4-positive cells were observed. The diagnosis was consistent with inflammatory pseudotumor. This disease entity, the histological differential diagnosis, its subtypes, and preoperative embolization are discussed.
