Hastanin hikayesinde nonsirotik portal hipertansiyon ve tekrarlayan kolanjit ataklari dikkat çekmekte idi.

Albendazol baslanacak bu tür hastalar kemik iligi toksisitesi yönünden sik kan sayimlari ile yakindan takip edilmeli, verilecek diger ilaçlara dikkat edilmelidir.
Albendazole has broad-spectrum coverage as an antiparasitic drug, and the reported side effects have been minimal. We report the case of a patient with febrile neutropenia beginning during the second week of therapy for a hepatic, splenic and peritoneal echinococcal cyst. This case was a 49-year-old man who presented with a large cystic abdominal mass. His medical history was significant for non-cirrhotic portal hypertension and recurrent cholangitis. Albendazole sulfoxide peak dose and half-life are significantly prolonged by liver disease and concomitant administration of certain drugs. The severity and duration of albendazole-induced neutropenia in this case was likely related to the underlying liver disease. Frequent serial monitoring of blood counts and cessation of medication with any evidence of marrow toxicity in such patients are warranted.
