Clinical history:
A 43 year old woman, who was otherwise healthy, presented to emergent care with newonset, severe headaches, nausea and vomiting. Her other medical history included
gestational diabetes and pregnancy-induced hypertension which resolved with delivery of
her child. History of previous malignancy was negative. Review of systems was
unremarkable. While in emergent care, head CT identified a left frontal temporal duralbased mass that prompted an outpatient neurosurgery referral.
In detail, Brain MRI showed a 3.2 cm extra-axial mass with dural tails located over the
left frontal operculum. The mass showed heterogeneous enhancement, and mass effect,
including minimal narrowing of the left lateral ventricle and minimal mid-line shift to the
right by 2 mm. Gross total resection was performed without complication. The postoperative diagnosis was meningioma. Post-operative imaging at 4 months showed dural
thickening and enhancement of the meninges subjacent to the craniotomy flap, which was
interpreted as reactive changes.
