Presentation
Referred for screening abdominal ultrasound due to chronic pelvic pain.
Patient Data
US demonstrated an inhomogenous circumscribed mass with no internal vascularity, connected to the left lobe of the liver.
The findings were correlated to a several years abdominal CT, which confirmed the lesion as a known hydatid cyst in the 3 segment of the liver, here visible as a well-defined round, low-density mass with peripheral calcifications and no contrast enhancement (bilateral small adrenal adenomas are also visible).
Case Discussion
US and CT appearance of a partially calcified long-standing hydatid cyst of the liver that underwent chronic changes, thus it displayed an unusually inhomogenous echogenicity on US, and an almost soft tissue density on CT.
