例1 女,30岁。于1981年1月发现左上腹有一约馒头大小包块,无特殊不适。1981年3月在外院做了腹部包块切除,术后恢复顺利。1982年10月又发现下腹有包块,除腹胀外,无尿频、尿急、排尿困难等症状,月经正常。入院时下腹饱满,左侧包块位置深,质地硬,右侧包块质地软,包块固定,无压痛。直肠指诊未见异常。血、尿常规正常,肝、肾功能试验正常。超声波提示下腹部多个混合性包块,边缘清楚,胃肠钡餐造影见有肠管受压现象,认为平滑肌瘤和肉瘤可能性大。参阅外院手术记录和病理报告,术前诊为“空肠平滑肌肉瘤。” Example 1 Female, 30 years old. In January 1981, it was found that there was a small amount of bread on the left upper abdomen without any special discomfort. Abdominal mass resection was performed in the outer court in March 1981, and the recovery was smooth. In October 1982, it was found that there was a mass in the lower abdomen. In addition to abdominal distension, there were no symptoms such as frequent urination, urgency, dysuria, and normal menstruation. The lower abdomen was full on admission, and the left mass was deep and hard. The right mass was soft and the mass was fixed. There was no tenderness. There was no abnormality in the digital rectal examination. Routine blood and urine tests were normal, and liver and kidney function tests were normal. Ultrasound revealed multiple mixed masses in the abdomen with clear edges. Intestinal barium meal angiography showed a phenomenon of bowel pressure. It is considered that leiomyomas and sarcomas are more likely to be present. See hospital records and pathology reports. Preoperative diagnosis was “jejunal leiomyosarcoma.”
