Liver cysts are etiologically classified into parasitic and non-parasitic cysts. The latter are differentiated into neoplastic, inflammatory, traumatic, and congenital [11]. The congenital, particularly solitary cysts, are distinctly rare. Their clinical presentation frequently poses a diagnostic and therapeutic challenge. A case of congenital multilocular liver cysts is reported. Review of relevant literature has been done, computed tomographic (CT) findings have been described and problem pertaining to differential diagnosis have been discussed.
Case ReportA 53-year-old Saudi female, mother of nine healthy children presented with the complaint of intermittent stabbing pain in the right hypochondrium with pyrexia of three days' duration. The pain radiated to the back and right shoulder. There was a history of similar attacks of pain since adolescence.On examination, the right upper abdomen was found to be tender. Two separate masses were felt in the epigastrium and right hypochondrium. Blood count showed leukocytosis of 12 × 10 3 with 7% bands, 68 polys, 17% lymphs, 13% monos, 2% eosinophils and 1% atypical lymphocytes. Hemoglobin was 12 g/dl. Total bilirubin was 12.1 μmol/L, total protein 70 g/L, albumin 24 g/L, GOT 104 IU/L, GPT 79 IU/L, LDH 231 IU/L, GGTP 249 IU/L. Hepatitis B surface antigen (HBsAg) and Casoni's test were negative.Ultrasound imaging and CT scan revealed a slightly enlarged liver with irregular outlines. Several hepatic cysts of varying attenuations and a single splenic cyst were reported. The largest cystic space measured 8.3 × 6.8 cm. Pancreas and kidneys were free (Figure 1).Exploratory laparotomy was performed with the tentative diagnosis of multiple hydatid cysts. The liver was found to be studded with multiple cysts of varying sizes. The smallest was 2 and the largest was 80 mm in diameter. The nature of aspirated fluid varied from cyst to cyst with watery in some, and turbid or purulent in others. The bacteriological and cytological examination did not reveal any bacteria, ameba or malignant cells. All cysts were tense and firm in consistency. Two large cysts, one in each lobe, were deroofed and filled with omentum. The remaining cysts were aspirated. The histology of the resected cyst walls revealed fibrous tissue without any epithelial lining. The underlying liver tissue showed marked inflammatory changes with liver cell necrosis and hemorrhage. There was no evidence of hydatid scolices or ameba in the tissue (Figure 2). Post-operatively, the liver function tests returned to normal. The pyrexia and pain disappeared and the patient was discharged 13 days following laparotomy.
