Kim, Lee, Koh, and Maeng: MR Imaging Findings of Supratentorial Meningeal Hemangioblastoma: A Case Report

Abstract

Hemangioblastomas account for 1.1–2.5% of intracranial neoplasms. These tumors most commonly occur in the cerebellum. A 77-year-old woman had a hemangioblastoma, which showed the supratentorial meningeal mass without any history of von Hippel-Lindau disease.

A 77-year-old woman with supratentorial meningeal hemangioblastoma.

A, B. Axial T1-weighted and T2 FLAIR image show a 3.7 cm, well-defined cystic mass (arrow) in the left frontal convexity. The cystic mass shows hypo signal intensity on T1-weighted MR image and high signal intensity on T2 FLAIR image. The cystic mass exhibits a high signal intensity portion (arrowheads) suggesting hemorrhage, on T1-weighted and T2 FLAIR images.
C. Coronal T2-weighted image shows plaque-like mural nodule (arrowhead) of intermediate to high intensity signal.
D, E. Axial and coronal gadolinium-enhanced T1-weighted fat-suppressed MR image show a rim-like enhancement of the mass (arrows) and plaque-like enhancing mural nodule (arrowheads).
F. Coronal gadolinium-enhanced T1-weighted fat-suppressed MR image shows dural tail with adjacent plaque-like enhancing mural nodule (arrow).FLAIR = fluid attenuated inversion recovery

Microphotographs showing numerous thin-walled vessels (A: H&E, × 200) and large, vacuolated stromal cells (B: H&E, × 400). Immunohistochemistry, highlighting the stromal cells, which are positive for NSE (C: × 200) and negative for EMA. Vascular endothelial cells reactive with CD31 (D: × 200) highlighting the positive reaction of stromal cells. Positive for NSE, negative for EMA, and positive for vascular endothelial cells of CD31 are inconsistent with meningioma.

EMA = epithelial membrane antigen, H&E = hematoxylin and eosin, NSE = neuron specific enolase
