A case of postbiopsy hemobilia is presented in which computed tomographic (CT) scanning showed blood within the gallbladder appearing as high-density material measuring 67-91 HU. Residual clots were seen by CT and ultrasound 8 days after the acute episode. These findings were confirmed by serial CT scans in two monkeys in whom blood was experimentally injected into the gallbladder. When the cystic duct is patent, the diagnosis of hemobilia may be excluded if bile of normal density (0-20 HU) is demonstrated by CT scanning. However, when homogeneous or inhomogeneous material of high attenuation (50+ HU) is present in the gallbladder on CT scanning, the diagnosis of hemobilia is strongly suggested if other causes such as stone or contrast material have been eliminated. CT may show residual blood for days after the acute episode.
本文报告一例活检后发生的胆道出血病例，其中计算机断层扫描（CT）显示胆囊内的血液表现为密度为67 - 91 HU的高密度物质。急性发作8天后，CT和超声检查发现了残留的血凝块。在两只经实验将血液注入胆囊的猴子身上，通过系列CT扫描证实了这些发现。当胆囊管通畅时，如果CT扫描显示密度正常（0 - 20 HU）的胆汁，则可排除胆道出血的诊断。然而，当CT扫描显示胆囊内存在均匀或不均匀的高衰减物质（50 + HU），且已排除结石或造影剂等其他原因时，则强烈提示胆道出血的诊断。急性发作后数天，CT可能仍显示残留血液。
