Cavernous sinus tuberculoma: diagnostic difficulties in a personal case.

BACKGROUND

Tuberculoma of the brain is rare, and its location in the cavernous sinus is exceptional. Many factors make the diagnosis difficult, necessitating a surgical procedure.

METHODS

A 44-year-old woman complained of persistent headaches and diplopia. The examination revealed a right cavernous sinus syndrome. Radiologic investigation showed a growing process in the right cavernous sinus, overlapping the sella turcica. The diagnoses of metastasis, tuberculoma, and sarcoidosis were considered, but none of them could be confirmed. A biopsy of the lesion via a subtemporal approach revealed a tuberculoma. Antituberculous treatment led to complete resolution of her symptoms.

CONCLUSIONS

The diagnosis of a cavernous sinus tuberculoma is difficult; it is confirmed by biopsy. However, a trial of medical treatment, if the results are favorable, may obviate the need for a surgical procedure.
