[Maffucci's syndrome with intracranial manifestation and chromosome abnormalities--a case report].

The patient was a 52-year-old woman who was initially admitted to our hospital with a recent history of diplopia, ptosis and visual impairment on the right, adding to 6 years history of the right orbital pain and temporal headache. She had gradually developed pain and fatigue of the right knee since childhood and had been suffered from multiple subcutaneous tumor in the both hands and the right foot from youth onward. On neurological examination, she has had right exphthalmos and 3rd and 6th cranial nerve palsies on the right. Skull X-ray and CT scan showed parasellar calcified mass on the right. In chromosome examination, the inversion of the No. 1 chromosome was disclosed by the Q- and C-band dyeing of her leucocytes and skin culture. Cavernous hemangioma of her skin lesion and enchondroma of the skeletal lesion were diagnosed by X-ray examination and histological specimen, indicating so-called Maffucci's syndrome. One year and a half later, she was readmitted to our institution, because of progressive visual loss on the right and left hemiparesis. Malignant change of the parasellar lesion was suspected by the clinical course and neuroradiological findings and was confirmed histologically by the second peration. During postoperative course, intratumoral hemorrhage had occurred twice and the patient died, and postmortem examination confirmed her clinical affair. This is the case which was clarified malignant transformation of enchondroma in the parasellar region, and is the first case verified the chromosome abnormalities in Maffucci's syndrome.
