Disseminated Alveolar Echinococcosis.

Abstract

Alveolar echinococcosis (AE) is caused by the larval form of the tapeworm Echinococcus multilocularis. In humans, E. alveolaris metacestode cells proliferate in the liver inducing a hepatic disorder that mimics liver cancer and can spread to other organs. From 1960 to 1972 mortality was at 70% and 94% after 5 and 10 years of follow-up, respectively. Since then, studies have shown an increasing trend towards improving survival rates [1]. As AE is also spreading to new areas of Eastern Europe, researchers seek to better understand the clinical presentation of pathology, including asymptomatic forms. Clinical case; One 36-year-old woman from Peshkopia has been admitted to the Gastrohephatology department on 20.07.2011 with fatigue, anorexia, dull pain in right hypochondrium, mild epigastric pain, bloating, and weight loss. The epidemiological anamnesis showed that the patient lived in the village and had pets. On physical examination, the patient appeared severely ill with jaundice, massive hepatomegaly, massive mass in the mesogastric area, and anxiety. Laboratory examinations were as follows: Hb 11.1 g/dl, sediment 25 mm/h; leukocytes 6700/mm3; platelets 127000/mm3; prothrombin level 60%, uremia 12.7 mmol/l; creatinine 0.78 mmol /l; ALP 127 U/I; AST 15 U/I; ALT 37 U/I; GGT 131 U/I; bilirubin 3.7 mg/l, albumin 2.8 gr / l, total protein 8.1 gr / l, HbsAg negative, anti-HCV negative. Regarding serology, the titer of anti-echinococcal antibodies was positive (22, n = 11) Conclusions: Clinical presentation and radiologic imaging findings of disseminated alveolar echinococcosis can mimic metastatic malignancy, and diagnosis can be challenging in atypically advanced cases. As the incidence of human alveolar echinococcosis appears to be increasing and, physicians should be aware of alveolar echinococcosis, its epidemiology, and its clinical features.
