Hepatic teratoma

Hepatic teratomas are extremely rare and represent either intraperitoneal or retroperitoneal teratomas that have invaded the liver. Hepatic teratomas comprise <1% of all teratomas.

Epidemiology

These are extremely rare with only a few case reports have been described in the literature. The majority are seen in children younger than 3 years of age.

Clinical presentation

These are mostly asymptomatic.

Pathology

See main article: Teratoma.

Radiographic features

CT

The findings depend on the relative components of the mass. Frequently, hepatic teratomas are well-defined masses containing fat, fluid, and calcification (mostly peripheral).

Treatment and prognosis

Complete surgical resection remains the best treatment option.
