肝海绵状血管瘤是最常见的肝脏良性肿瘤,尸检发现率为0.4%～7.3%。近年由于肝脏影像学检查技术的进步,尤其临床上B超的广泛应用,本病的检出率日渐增高。但是从剖腹探查病例所见,肝脏小囊肿较小血管瘤更为多见,在正常肝组织中约为20%～40%。此可能因为小囊肿容易触到,而小血管瘤主要以视诊为主,触诊反而不易查出。对肝内疑诊的病变,经针吸法可立即作出鉴别诊断。肝血管瘤分为小的毛细血管瘤和较大的海绵状血管瘤。前者虽较多见,但无重要临床意义;后者实际上较肝脏其它良性实质性肿瘤为多,可合并肝囊肿和肝腺瘤。但很少与肝硬变同时存在。肝脏是血管瘤最好发的内脏器官。文献报道最大者重18160g,切除的最大肿瘤重约500～600g。我所于1975年2月8日曾成功地切除了1例重为18000g、体积为63cm×48.5cm×40cm的特大肝海绵状血管瘤。现已术后18年,仍健康存活。本病病因学上认为是先天性病变而非新 Hepatic cavernous hemangiomas are the most common liver benign tumors, and the autopsy findings were between 0.4% and 7.3%. In recent years, due to advances in liver imaging techniques, especially the widespread use of B-ultrasound in clinics, the detection rate of this disease has been increasing. However, as seen from the case of exploratory laparotomy, small hemangiomas are more common in small hepatic cysts, and are about 20% to 40% in normal liver tissue. This may be because small cysts are easily accessible, while small hemangiomas are mainly based on visual inspections, but palpation is not easy to detect. For suspected lesions in the liver, a differential diagnosis can be made immediately by needle aspiration. Hepatic hemangiomas are divided into small capillary hemangiomas and larger cavernous hemangiomas. Although the former is more common, it has no clinical significance; the latter is actually more than other benign solid tumors in the liver and can be combined with hepatic cysts and hepatic adenomas. However, it rarely occurs with cirrhosis. The liver is the best internal organ for hemangiomas. The maximum weight of 18160 g was reported in the literature, and the largest tumor excised was about 500-600 g in weight. On February 8, 1975, we successfully removed a giant hepatic cavernous hemangioma weighing 18,000 g and a volume of 63 cm x 48.5 cm x 40 cm. It has been healthy for more than 18 years after surgery. The etiology of the disease is considered congenital lesions rather than new
