Angiolipoma of suprasellar region.
An angiolipoma of the suprasellar region occurred in an 8-year-old boy. Review of 5 intracranial angiolipomas, including the current case, revealed that four were in the sellar region of one man and three women. One was in the thalamus of a man. The average age of the patients was 49 years, and average size of the tumors was 2.5 cm across. The angiolipomas associated with the sellar region often created abnormalities of the eye viz exophthalmos, decreased vision, and palsy of the oculomotor nerve. Sudden onset has ensued in a massively hemorrhagic thalamic angiolipoma. The characteristic low density with negative Hounsfield unit values in CT scan and hyperdensity in MRI of the brain suggested adipose tissue component of the angiolipoma. The angiography has depicted the angiomatous component of the latter. The combined characteristic CT scan, MRI, and angiographic features should demonstrate both vascular and adipose tissue elements of the angiolipomas before pathologic examination.
