We reviewed the unenhanced computer tomography (CT) scans of 53 patients with surgically proven acute cholecystitis, where 27 patients presented with hyperdense gallbladder wall. To our knowledge, this sign was never reported before. Because mucosa is highly sensitive to ischemia, early mucosal necrosis and hemorrhage may result in CT-detectable high density. Similar episode may also occur in acute cholecystitis. This sign also reflects high probability for acute gangrenous cholecystitis. We suggest that patients with this sign should have urgent treatment.
我们回顾了53例经手术证实为急性胆囊炎患者的平扫计算机断层扫描（CT）图像，其中27例患者胆囊壁呈高密度。据我们所知，此征象此前从未有过报道。由于黏膜对缺血高度敏感，早期黏膜坏死和出血可能导致CT可检测到的高密度。类似情况也可能发生在急性胆囊炎中。此征象还提示急性坏疽性胆囊炎的可能性很大。我们建议有此征象的患者应接受紧急治疗。
