[Multiple cerebral tuberculomas presenting with paradoxical expansion: a case report].

: A 24-year-old male presented with headache. He had been treated with antituberculous drugs for 19 months. MRI revealed 4 intracranial Gd-DTPA enhanced lesions surrounded by massive edema in the right frontal, both occipital and left basal ganglionic regions. Digital subtraction angiography showed no tumor stain. Two procedures for tumor resection were performed for the right frontal and left occipital regions, the latter of which definitively diagnosed by the polymerase chain reaction method. The tumors were well demarcated, showed a rough surface, and were elastically hard. The two residual lesions responded differently to chemotherapy. The lesion in the right occipital region decreased in size, while the other in the left basal ganglionic region continued to grow gradually 26 months after the antituberculous chemotherapy was started. According to previous reports, treatment should be continued for as long as 12-30 months in cases showing paradoxical expansion. In this case, the left basal ganglionic lesion began to decrease in size after 28 months of administration of anti-tuberculous drugs. We report successful treatment of a case of multiple tuberculomas presenting with paradoxical expansion managed by a combination of surgery and continuous chemotherapy.
