BACKGROUND: Cystic liver lesions include hepatic echinococcosis as an important differential diagnosis, especially in patients from endemic countries. Serology might be false negative in a relevant percentage of the patients. Thus, modern clinical imaging techniques are the most important non-invasive means for making or excluding the diagnosis of hepatic echinococcosis. CASE REPORT: A 37-year-old Turkish woman was admitted to hospital because of abdominal pressure, lack of appetite and weight loss. The suspected radiological diagnosis of hepatic echinococcosis was made based on a septated, cystic liver process with calcifications seen in an already performed computered tomography. The physical examination and laboratory findings did not show any specific pathology. The serological tests for echinococcosis were negative. The MRI scan of the liver showed a 10 x 7.5 cm large, multi-segmented, cystic lesion between the right kidney and the right liver lobe. The cyst was discussed as possibly having an origin from the right adrenal gland and very unlikely from the liver or kidney. Ultrasonography (Siemens-Acuson Sequoia 512, Mountain View) showed a cystic lesion with septated structures and calcifications between the right kidney and the liver without a typical capsule. Contrast-enhanced ultrasound after fractionated injection of 4.8 mL Sonovue (Bracco, Milano) showed an intensive perfusion of the septa in the cyst. We admitted the patient for surgery. Interoperatively a right adrenalectomy and cystectomy was performed. Histology showed an epithelial adrenal cyst. The patient was asymptomatic twelve months after surgery. CONCLUSION: High-end-ultrasonography with microbubble contrast media of the second generation is the primary diagnostic tool for the differential diagnosis of cystic lesions of the liver and adrenal glands. MRI or CT scans might be additionally indicated in the case of poor ultrasound conditions in a patient or before planned surgery, but can also fail to correct determine the origin of a cyst.
