胃平滑肌肿瘤较少见,约占消化道肿瘤的1％,常规X线及CT诊断时有报道,而MR诊断报道甚少,我们遇到两例,报告如下: 例1,男45岁,体检时B超发现肝区包块,拟肝囊肿。查体:腹软,肝可触及,无触痛。CT示肝左叶下方软组织肿块影,CT值33Hu,与肝分界不清。增强后病灶有强化,CT值49Hu。诊断为肝左叶下方占位性病变。患者无任何不适。MR表现:平扫见肝方叶下方与胃窦之间有约70×73×63mm软组织肿块,周边光整且无分叶。SE序列T_1加权像与肝和胃壁信号相
Gastric smooth muscle tumors are rare and account for about 1% of digestive tract tumors. Routine X-ray and CT diagnosis have been reported. MR diagnosis is rarely reported. We encountered two cases. The report is as follows: Example 1, male 45 years old, physical examination When B ultrasound found liver masses, hepatic cysts. Physical examination: Soft abdomen, palpable liver, no tenderness. CT showed a soft tissue mass below the left hepatic lobe with a CT value of 33 Hu, which was unclear to the liver. After enhancement, lesions were enhanced with a CT value of 49 Hu. Diagnosed as a space occupying lesion below the left lobe. The patient did not have any discomfort. MR manifestations: There were approximately 70×73×63 mm soft tissue masses between the lower part of the liver and the antrum, and the surrounding area was smooth and undivided.
