We present a unique case of liver echinococcosis presenting as recurrent abdominal wall fistula and abscess in a 29-year-old man. Diagnosis was based on CT imaging, serological analysis and histological findings from the fistula. [casereports.bmj.com]

• Pseudotumor

  Practice Essentials Key observations and recommendations for alveolar echinococcosis (AE) in clinical practice are as follows: Alveolar echinococcosis is a rare pseudotumor zoonotic parasitic disease of the liver that is distinct from cystic echinococcosis [emedicine.com]

• Abdominal Pain

  […] echinococcosis that is caused by the larvae of Echinococcus multilocularis affecting the liver as a slow growing, destructive tumor, with abdominal pain, biliary obstruction, and occasionally metastatic lesions into the lungs and brain AHD alveolar colloid [wikidata.org]

  This leads to signs and symptoms of upper abdominal pain, chest pain, and cough with sputum and blood The treatment of Echinococcus is undertaken using anti-parasitic medications and sometimes, the condition may require surgical interventions. [dovemed.com]

  The most common presenting signs and symptoms were abdominal pain with hepatomegaly and liver mass. Most of the patients were treated by surgery and albendazole. The few unresectable liver masses were treated by medical therapy. [ncbi.nlm.nih.gov]

• Hematemesis

  Later petechiae, hematemesis, and bloody diarrhea developed. He became rapidly cachectic and died 3 months after the onset of jaundice. Virchow then gives a pictorial description of the autopsy he performed on March 5, 1855. [ncbi.nlm.nih.gov]

• Liver Mass

  The most common presenting signs and symptoms were abdominal pain with hepatomegaly and liver mass. Most of the patients were treated by surgery and albendazole. The few unresectable liver masses were treated by medical therapy. [ncbi.nlm.nih.gov]

• Petechiae

  Later petechiae, hematemesis, and bloody diarrhea developed. He became rapidly cachectic and died 3 months after the onset of jaundice. Virchow then gives a pictorial description of the autopsy he performed on March 5, 1855. [ncbi.nlm.nih.gov]

• Multilocular Cyst

  The patients in whom he diagnosed the disease had multilocular cysts with an alveolar aspect, resembling European AE. Notably, the patients came from rural areas and claimed that they had never been out of the country ( 4 – 6 ). [ncbi.nlm.nih.gov]

• HLA-B8

  Notably the HLA B8, DR3, DQ2 haplotype was associated with more severe forms of this granulomatous parasitic disease. [ncbi.nlm.nih.gov]

• HLA-DR3

  PBMC from seven HLA-DR3 , DQ2 , B8 healthy subjects and nine HLA-DR3-, DQ2-, B8- subjects were also studied as controls. [ncbi.nlm.nih.gov]

The cost of the hospitalization and treatment of the eight screened patients would appear to be relatively high. Even though two of them were asymptomatic, they had very severe forms of the disease. [ncbi.nlm.nih.gov]

Surgical resection of primary lesions allows curative treatment. [cid.oxfordjournals.org]

Prognosis Untreated alveolar echinococcosis is usually fatal, with an average 5-year survival rate of 40%. Therapeutic approaches that have been developed since the early 1980s have markedly improved the prognosis of the disease. [emedicine.com]

The introduction of benzimidazoles for alveolar echinococcosis treatment in 1976 has considerably improved the prognosis ( 2, 3 ). [ncbi.nlm.nih.gov]

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]

AE (the disease) is not endemic in Canada; its etiological agent, Echinococcus multilocularis, is. 2. [cmaj.ca]

However, with the description of a new indigenous species, uncertainties arose about the etiologic role of E. oligarthrus in PE ( 30 ). [ncbi.nlm.nih.gov]
