SANCHEZ T, Felipe Antonio; ZUGBE G, Nicolás; LUCIA C, María Eugenia  y  MORAGA L, Marcela. Polycystic liver hemangioma mimicking a hydatid cyst: A case report and review of the topic. Rev. chil. radiol. [online]. 2014, vol.20, n.4, pp.164-167. ISSN 0717-9308.  http://dx.doi.org/10.4067/S0717-93082014000400008.

Introduction: Cavernous hemangiomas are the most common benign mesenchymal hepatic tumor. Most have a typical appearance, but atypical forms have been reported that can make diagnosis difficult. Objective: To show a case of cystic hemangioma mimicking a hydatid cyst. Case: 60 year old woman with abdominal pain. Abdominal ultrasound: polycystic lesion with parietal calcifications, 6 cm in size, in the left hepatic lobe. Computed tomography of the abdomen shows the lesion as a simple cyst. During conversation the patient revealed she lives with 13 dogs. Hydatid disease was suspected and treatment with albendazole and segmental hepatectomy was indicated. A hemorrhagic tumor biopsy compatible with infarcted hemangioma was obtained. Discussion: The typical hepatic hemangioma is presented in ultrasound as an echogenic mass with posterior acoustic enhancement. The contrasted CT also presents with a classic pattern. Among the atypical presentations the cystic form is extremely rare and has only been mentioned in a few reports.

Palabras clave : Atypical hemangioma; Hemangioma cyst; Hydatid cyst.
