[Neurinoma of the short ciliary nerve: a case report]

Intraorbital neurinoma is a rare tumor and constitutes nearly 1.5% of the orbital tumors. A case of orbital neurinoma is reported. A 70-year-old woman was admitted with the chief complaint of impairment of visual acuity and proptosis of the left eye. A CT scan and MRI revealed a retrobulbar mass. Total removal of the tumor via the transcranial approach to the orbita resulted in improvement of the symptoms. The tumor was considered to be a neurinoma originating from the left short ciliary nerve.
