1068 Cranial Fasciitis of the Temporal Bone

Abstract We present the case of a child with rare benign tumour temporal bone. A nine-month-old girl was referred to her local paediatric hospital painless right-sided, post-auricular swelling increasing in size preceding two months. On examination there 2x2cm mass overlying bone posterior right ear. The firm, immobile, non-tender and well circumscribed. Ultrasound demonstrated 1.9cm subcuticular evidence intracranial extension through suture. Vascular flow hyperechoic foci were within lesion. team requested magnetic resonance imaging (MRI) computed tomography (CT) prior referral tertiary care centre. Imaging displayed 2cm expansile lesion cortical loss effacement underlying dural venous sinus. patient proceeded incisional biopsy for tissue diagnosis which suggestive cranial fasciitis. Following discussion at regional multidisciplinary meeting, she underwent surgical excision joint Neurosurgery/Otology case. fully resected macroscopically, normal surrounding mastoid air cells preserved. Final histopathology showed highly cellular composed spindle arranged fascicles, areas myxoid background confirmed be has made good recovery will kept under close clinical follow-up. This demonstrates that may an otolaryngologist importance diagnosis, management.
