目的探讨小灶性脑出血的临床特点、治疗和预后。

Objective To study the clinical features, treatment and prognosis of focal cerebral hemorrhage.

切面可见有扩张的小囊，肿瘤可见有小灶出血和坏死。

On sectioning, they contain dilated small cysts, with foci of haemorrhage and necrosis.

结果18例中，5例呈小灶致密影，6例出现局部结构紊乱，7例显示为星芒征。

Results Among 18 patients, 5 cases showed small focus of increased density, 6 cases had focal architecture distortion, 7 cases demonstrated star sign.

肿瘤术前应用可局限瘤体，减少术中缺血；术后应用可进一步消除微小灶，防止肿瘤复发和转移。

Preoperative tumor treatment can limit the tumor, reduce ischemia during the operation. Postoperation treatment can eliminate the microscopic cancers, prevent the tumor recurrence and migrate.

根据组织学坏死程度分组，小灶性坏死组平均摄取比为1.73，部分性坏死组摄取比为1.02，广泛性坏死组摄取比为0.68。

The mean uptake ratio was 1.73 in the group with minimal necrosis, 1.02 in the group with partial necrosis and 0.68 in the group with extensive necrosis.
