Abstract:
[ABSTRACT]OBJECTIVETo study clinical features and imaging manifestations of facial nerve hemangioma. METHODSClinical data of 5 cases with facial nerve hemangioma, who were diagnosed and treated in facial lab of Beijing Shijitan hospital between January 2006 and December 2011, were collected. There were 2 male and 3 female. The age ranged from 29-44 years. Among the 5 cases with facial nerve hemangioma, both HRCT of temporal bone and facial nerve enhancement MRI were performed on 4 cases, and one case underwent facial nerve enhancement MRI examination only.RESULTSAll the 5 cases firstly presented with sudden unilateral facial palsy. Facial palsy affected the left and right side in 4 cases and 1 case, respectively. Geniculate ganglion was affected in all cases. Local bony canal expansion at geniculate ganglion, labyrinthine segment and horizontal segment was the main manifestation of facial nerve hemangioma on HRCT, and the surrounding bone was incontinuous and less regular. The typical appearance was point-shape or pin-shape, similar to honeycomb structure. On MRI, soft tissue node image around geniculate ganglion accompanied by thickness of the adjacent facial nerve was the chief appearance. It showed mixed T1, uneven and slightly longer T2 signal with less clear border on horizontal scanning, and abnormal enhancement was exhibited after enhancement scanning.CONCLUSIONDetailed history together with HRCT of temporal bone and multi-planar reconstruction MPR as well as facial nerve enhancement MRI were useful for preoperative diagnosis of facial nerve hemangioma. The tumor should be removed with surgical approach was based on hearing conditions, tumor scale and the affected sites.in order to preserve integrity of facial nerve if possible.
