A case of liver echinococcosis mimicing a solid liver tumor.
A case of hepatic echinococcosis mimicing a solid tumor was presented. The echinococcosis appeared as an echogenic mass in US, a low density area in CT, and an area of low (T1-weighted image) and high (T2-weighted image) intensity in MRI. Echo-guided biopsy showed PAS-positive cuticle layer of echinococcus in the necrotic tissue. Anular features around the lesion noted in MRI seemed to imply increased hepatic tissue water (congestion and/or edema). When a solid tumor is noted in the liver, proper history taking and awareness of this disease will decrease the chance of misdiagnosis.
