Figure 14  A 67-year-old male who underwent multiphasic abdominal computed tomography scan demonstrated a lesion with gross calcifications in S3 that did not present contrast enhancement in any phase. Liver magnetic resonance imaging confirmed a nodular formation, hypointense on T1-weighted sequences, isointense on long TR sequences with more hypointense components corresponding to calcification on computed tomography images, without significant restriction on diffusion weighted images and hypointense on the hepatobiliary phase. These features are consistent with a calcified echinococcal cyst. A: Unenhanced liver computed tomography (CT); B: Portal venous phase of liver CT; C: In-phase T1-weighted image; D: T2-weighted image; E: ADC map; F: Portal venous phase of liver CT; G: Delayed phase of liver CT; H: Out-of-phase T1-weighted image; I: T2-Spectral Attenuated Inversion Recovery; L: Hepatobiliary phase magnetic resonance imaging.
