A 17-years-old man with the juvenile form of MLD developed massive hemobilia. CT and US scans showed blood and clots filling the gallbladder and the biliary ways, with no bleeding source seen at selective angiography. Explorative laparotomy evidenced bleeding from a papillomatous gallbladder mucosa, resolved with cholecystectomy. Histologic examination with specific colorations diagnosed hemorrhagic cholecystitis from metachromatic leukodystrophy of the gallbladder. This is, to our knowing, the third case reported in Literature, and thus hemorrhagic cholecystitis may be considered a life-threatening complication of MLD to be prevented with cholecystectomy as soon as signs of gallbladder pathology (papillomatosis/polyposis, jaundice, abdominal pain) are suspected.
一名患有青少年型异染性脑白质营养不良(MLD)的17岁男性发生了大量胆道出血。CT和超声扫描显示血液和血凝块充满胆囊及胆道,选择性血管造影未发现出血源。剖腹探查发现出血来自乳头状胆囊黏膜,行胆囊切除术后出血停止。通过特殊染色的组织学检查诊断为胆囊异染性脑白质营养不良所致的出血性胆囊炎。据我们所知,这是文献报道的第三例,因此出血性胆囊炎可被视为MLD的一种危及生命的并发症,一旦怀疑有胆囊病变(乳头状瘤病/息肉病、黄疸、腹痛)迹象,应尽早行胆囊切除术以预防。
