[A Surgical Case of Tuberculoma with Visual Disturbance].

ABSTRACT

We herein report a surgical case of multiple cerebral calculi located within the chiasmatic cistern resulting in visual disturbance. A 61-year-old man experienced homonymous lower right quadrantanopsia a few years prior. Non-enhanced head CT revealed multiple calcified lesions of about 7-mm within the basal cistern. MRI showed the lesion compressing the left optic tract. We could not remove the entire lesion because of severe adhesion to the optic tract. A pathological test showed calcified lesions with lymphocyte infiltration. We diagnosed tuberculoma caused by tuberculous meningitis with degeneration of the calcified lesion because of a history of tuberculosis at a fetal age. After the surgery, the patient was discharged without improvement of the visual disturbance.
