“…HARDIN et al (3) reported CT evaluation of 16 tumors involving the masticator space, but only 4 originated in this region (2 sarcomas and 2 malignant schwannomas). The CT and MR findings in one case of masticator space meningioma and one case of intramuscular hemangioma have previously been published ( 1,6), and in a series of MR evaluations of head and neck rhabdomyosar- (10). WORK et al (9) presented 3 cases of lymp h o m a s in the masticator space, b u t only in one patient was the single manifestation of disease located t o the masticator space.…”

A retrospective study of CT and MR examinations in 14 patients with benign and malignant tumors originating in the masticator space is presented. At presentation, 12 patients revealed tumor extension to adjacent regions and spaces. Perineural tumor spread along trigeminal nerve branches to the cavernous sinus and orbits was combined with facial pain, and/or numbness, ophthalmoplegia, and exophthalmus. Detailed analysis of tumor growth and spread, enhancement and signal features at CT and MR imaging indicated that tumor histology was, with a few exceptions, nonspecific. More extensive growth and bone destruction was noted only among malig nant tumors. MR imaging was found superior to CT in delineating tumor extension due to better soft tissue contrast resolution and multiplanar imaging. Posttreatment examinations were available in 11 patients and showed long-standing regional edema of the adja cent temporal lobe and masticator muscles in 4 out of 5 patients without clinical evidence of tumor. In 6 patients, CT and MR features were found almost unchanged with only small size differ ences after various forms of treatment.

“…Neoplasms originating in the masticator space are uncom mon, and only a limited number of cases examined with CT and/or MR imaging have previously been presented (1,3,6). We present a retrospective analysis of the CT and MR examinations in 14 patients with benign and malignant tumors originating in the masticator space.…”

Recurrent extracranial sinonasal meningioma presenting 27 years after complete surgical eradication of right frontal meningioma

A 79-year-old man presented to our department with nasal obstruction and postnasal drip. On examination he had unusual bilateral nasal polyps, which were histologically diagnosed as meningioma. Twenty-seven years earlier he had undergone successful removal of a right frontal meningioma. A CT scan performed 7 years after his primary surgery had shown complete excision with no evidence of recurrence. Extracranial meningiomas are rare tumours and are usually extensions from an intracranial mass lesion. We document what we believe to be the first case of an extracranial meningioma, presenting as nasal polyps, 27 years after successful surgical eradication of the primary lesion.
