[Multiple myeloma presenting with multiple subcutaneous masses].

A 92-year-old female was admitted to our hospital with 2-months history of rapidly enlarging subcutaneous masses in the multiple skull's regions. Neurological examination in the admission showed slightly right hemiparesis. Skull X-P showed multiple osteolytic lesions, and CT showed high density masses. MRI revealed iso-intensity masses on both T1 and T2-weighted images. Gd-DTPA enhanced T1-weighted image showed masses with marked homogeneous enhancement like the dural tail sign in the dura adjacent to the tumors. The tumor in the right frontal subcutaneous region was partialy removed; this mass was diagnosed as multiple myeloma. Because the prognosis of such a case was very poor and she was older, we thought her quality of life (QOL) and she was conservatively treated. A case of multiple myeloma having plasmacytoma in multiple skull's regions was reported. Although 30 cases in the literature of multiple myeloma forming cranial or intracranial plasmacytoma were briefly reviewed, multiple lesion was not reported and we thought it as a very rare case. And if such a case was performed to remove all masses, we believed that three dimensional computed tomography images to distinguish the tumors from skull and skin (Perspective 3D-CT; SIEMES's Somatom Emotion 6 and Syngo) was very valuable for the preoperative evaluation of a surgical approach.

[Treatment of subarachnoid hemorrhages in an isolated mountainous area].

From January 1997 to December 2001, patients with subarachnoid hemorrhage (SAH) among 14,008 residents in an isolated mountainous area; Oguni and Minamioguni towns in Kumamoto Prefecture, were evaluated. The subjects were patients being treated at Oguni Municipal Hospital. Over a period of 5 years, 19 patients were found to be suffering from SAH in this area, 3 of whom were visitors (residing outside this area). The annual incidence rate of SAH in this area was calculated as 22.9 per 100,000. The sex ratio (men:women) was 4:12. The average age was 67.9 years; 65.0 years for men and 68.8 years for women. Eleven patients were older than 65, and constituted 68.8% of the subjects. The risk factors of SAH were recognized, and both hypertension and smoking constituted 31.6%. Alcohol was 21.1% and hyperlipemia was 15.8%. In 13 clipping operated cases excluding 1 test craniotomy, Hunt & Kosnik's Grades at admission were G.I: 2, G.II: 5, G.III: 3, G.IV: 2 and G.V: 1, and Fisher's Groups were G.I: 0, G.II: 8, G.III: 3 and G.IV: 2. The sites of 16 operated aneurysms were internal carotid-posterior communicating artery (IC-PC): 2, anterior communicating artery (A Co.A): 4, middle cerebral artery (MCA): 10 and vertebral artery-basilan artery (VA-BA): 0. The aneurysmal size were < 5 mm: 5, 6-10 mm: 9 and 11 mm < :2 (average 7.6 mm, 2-15 mm). The results were evaluated at discharge, excluding 1 SAH of unknown etiology. 9 were good, 2 were dependent and 7 including 5 non-operative cases had died. We were satisfied with these results, because we were treating older patients. Although we attempted the clipping operation using only a three dimensional computed tomographic angiograply (3D-CTA; X-Vision GX (TOSHIBA) & X-Tension), we had no problem, except for 1 test craniotomy. 3D-CTA was useful during the clipping operation in the small hospital, especially, in regard to cost.
