Vascular Hamartoma of Cerebellopontine Angle: A Rare Case Report
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 5
Abstract
Cerebellopontine angle (CPA) hamartoma is rare. Roughly, 90% of CPA tumors are acoustic neuromas. Other prevalent lesions include meningiomas and epidermoid tumors, and additional lesions are rare. We present a case of 12-year-old girl who presented with left-sided hearing loss of more than 1-year duration with vertigo since childhood and headache. Magnetic resonance imaging revealed a brilliantly enhancing lesion in the left CPA extending through tent in the supratentorial region. Lesion was eroding the posterior petrous and occipital bone, extending into the subgaleal planes, causing hydrocephalus. Computed tomography imaging shown hyperdense lesion in the left CPA. She opted for surgery, lesion excised and pathology confirmed a diagnosis of left-sided CPA hamartoma (vascular). Neurosurgeons and otolaryngologists should be familiar with this uncommon tumor and include it in the differential diagnosis of CPA lesions.
