A rare case of cerebellar angiolipoma in a 9-year-old girl

Abstract

Angiolipomas are slow-growing, benign soft tissue tumours consisting of mature adipocytes and thin-walled blood vessels. While most angiolipomas are subcutaneous lesions in the trunk and upper extremities, rarely they can present at cranial sites, mostly intraosseous and very rarely intracranial sites e.g., sellar region, fronto temporal lobes and even intraventricular. We presented a 9-year-old girl with one month history of vertigo. Otherwise, there was no remarkable neurological deficits. Magnetic resonance imaging (MRI) revealed a cerebellar lesion which was homogenously hyperintense on T1WI and T2WI, while signals were suppressed on short tau inversion recovery (STIR) but not on diffusion weighted imaging (DWI), corresponding to mainly fatty tissue signals.
