Giant Calvarial Cavernous Hemangioma: A Rare Case Report and Review of Literature

Primary intraosseous cavernous hemangiomas (PICHs) are benign vascular lesions that may occur in any part of the body. They account for 0.2% of all bone tumors and 10% of benign skull tumors. PICHs are usually seen in vertebral column and very rarely involve skull. We report a 36-year-old female patient with large right parietal cavernous hemangioma. The lesion had been excised completely with a good neurological outcome.

Imaging of focal calvarial lesions

Focal calvarial lesions may present as a visible, palpable, or symptomatic lump; however, with increasing use of cross-sectional imaging they are often encountered as an incidental finding. Knowledge of the possible disease entities along with a structured approach to imaging is required to suggest an appropriate diagnosis and assist in management planning. Abnormalities range from common neoplastic lesions to rarer congenital conditions, benign pathologies, and calvarial defects that can mimic lesions. The aim of this article is to demonstrate the salient imaging features that may help to limit the differential diagnosis of a focal calvarial lesion.

Giant primary ossified cavernous hemangioma of the skull in an adult: A rare calvarial tumor

Primary intraosseous cavernous hemangiomas (PICHs) of the cranium are rare benign vascular tumors that account for about 0.2 % of all bone tumors and 10 % of benign skull tumors. They generally present as osteolytic lesions with honeycomb pattern of calcification. Completely ossified cavernous hemangioma of the calvarium in an adult has not been reported previously. A 28-year-old female presented to us with a large right parietal skull mass that had been present since the last 15 years. Total resection of the lesion was performed. Pathological examination was suggestive of cavernous hemangioma of the skull bone. Cavernous hemangioma should be considered as one of the differential diagnosis in any case of bony swelling of the calvarium so that adequate preoperative planning can be made to minimize blood loss and subsequent morbidity.
