Intracranial gossypiboma: an under-reported entity.

摘要

A 23-year-old man presented to us with a recurrent skull base chondrosarcoma (having undergone surgery elsewhere 2 years ago). He had a large swelling in the right temporal region extending into the lateral orbit (producing proptosis) and involving the ipsilateral maxilla and mandible. He was blind in the right eye and had right-sided fifth nerve palsy (since the time of first surgery). Magnetic resonance imaging (MRI) revealed a large tumor of heterogenous intensity [Figure 1b-d] involving the right temporal bone extending into the infratemporal fossa, orbit, maxilla and the ipsilateral mandible with intracranial extension into the middle cranial fossa. A uniformly hypointense (on T1- as well as T2-weighted MR images) well-rounded lesion in the temporal base was noted, which retrospectively was realized to be the gauze piece. We acknowledge that in view of the extent and heterogeneity of the lesion, we did not consider this possibility preoperatively.
