Pheochromocytoma of urinary bladder are rare tumors. They present with nonspecific clinical signs and symptoms, so imaging plays an important role in diagnosing and localizing the tumor. We present two cases of bladder pheochromocytoma, one of them presented with vague abdominal pain and the other with hematuria. Biphasic CT in both the cases showed hypervascular intravesical mass suggestive of bladder pheochromocytoma. The lesions were confirmed biochemically or on postoperative histopathology. A brief review of the imaging in bladder pheochromocytoma is also presented.
膀胱嗜铬细胞瘤是罕见肿瘤。它们表现出非特异性的临床体征和症状，因此影像学在肿瘤的诊断和定位中起着重要作用。我们报告两例膀胱嗜铬细胞瘤病例，其中一例表现为模糊的腹痛，另一例表现为血尿。两例病例的双期CT均显示膀胱内血管丰富的肿块，提示膀胱嗜铬细胞瘤。病变通过生化检查或术后组织病理学得到证实。本文还对膀胱嗜铬细胞瘤的影像学表现进行了简要综述。
