Cavernous hemangioma of the gallbladder. Case report and review of the literature.
Hemangiomas are common benign tumors; they frequently occur in the liver but very rarely in the gallbladder, with only seven cases reported in the scientific literature to date. We here report an additional patient, a 49-year-old white woman presenting with an echogenic lesion of the gallbladder that was incidentally discovered. Cholecystectomy was performed after computed tomography had revealed a gallbladder neoplasm; pathological examination showed the mass to be a cavernous hemangioma. No postoperative complications occurred and the patient is alive and free of recurrence five years after the operation. We present a review of the literature on this topic with special emphasis on the diagnostic and therapeutic challenges these lesions may entail. Hemangiomas of the gallbladder may have extremely variable presentations (from non-specific abdominal pain to acute syndromes resembling cholangitis or choledocholithiasis) and can mimic different lesions (liver tumors, sarcoma). Only surgical exploration can provide a correct diagnosis. Excision is indicated as these lesions may grow to huge sizes, compress adjacent structures or bleed.


CONCLUSIONS
Gallbladder hemangiomas are uncommon benign tumors. A preoperative diagnosis is difficult to make. Surgical excision is mandatory both in reaching a final diagnosis and in preventing bleeding or compression of vital structures.
