Hydatid cyst of the pancreas: Report of an undiagnosed case of pancreatic hydatid cyst and brief literature review

Abstract

AIM:To overview the literature on pancreatic hydatid cyst (PHC) disease, a disease frequently misdiagnosed during preoperative radiologic investigation. METHODS:PubMed, Medline, Google Scholar, and Google databases were searched to identify articles related to PHC using the following keywords: hydatid cyst, hydatid disease, unusual location of hydatid cyst, hydatid cyst and pancreas, pancreatic hydatid cyst, and pancreatic echinococcosis. The search included letters to the editor, case reports, review articles, original articles, meeting presentations and abstracts that had been published between January 2010 and April 2014 without any restrictions on language, journal, or country. All articles identified and retrieved which contained adequate information on the study population (including patient age and sex) and disease and treatment related data (such as cyst size, cyst location, and clinical management) were included in the study; articles with insufficient demographic and clinical data were excluded. In addition, we evaluated a case of a 48-year-old female patient with PHC who was treated in our clinic. RESULTS:A total of 58 patients, including our one new case, (age range: 4 to 70 years, mean ± SD: 31.4 ± 15.9 years) were included in the analysis. Twentynine of the patients were female, and 29 were male. The information about cyst location was available from studies involving 54 patients and indicated the following distribution of locations: pancreatic head (n = 21), pancreatic tail (n = 18), pancreatic body and tail (n = 8), pancreatic body (n = 5), pancreatic head and body (n = 1), and pancreatic neck (n = 1). Extra-pancreatic locations of hydatid cysts were reported in the studies involving 44 of the patients. Among these, no other focus than pancreas was detected in 32 of the patients (isolated cases) while 12 of the patients had hydatid cysts in extra-pancreatic sites (liver: n = 6, liver + spleen + peritoneum: n = 2, kidney: n = 1, liver + kidney: n = 1, kidney + peritoneum: n = 1 and liver + lung: n = 1). Serological information was available in the studies involving 40 patients, and 21 of those patients were serologically positive and 15 were serologically negative; the remaining 4 patients underwent no serological testing. Information about pancreatic cyst size was available in the studies involving 42 patients; the smallest cyst diameter reported was 26 mm and the largest cyst diameter reported was 180 mm (mean ± SD: 71.3 ± 36.1 mm). Complications were available in the studies of 16 patients and showed the following distribution: cystobiliary fistula (n = 4), cystopancreatic fistula (n = 4), pancreatitis (n = 6), and portal hypertension (n = 2). Postoperative follow-up data were available in the studies involving 48 patients and postoperative recurrence data in the studies of 51 patients; no cases of recurrence occurred in any ORIGINAL ARTICLE Submit a Manuscript: http://www.wjgnet.com/esps/ Help Desk: http://www.wjgnet.com/esps/helpdesk.aspx DOI: 10.4240/wjgs.v6.i10.190 World J Gastro...

Hydatid Cyst of Pancreas: A Rare Case at a Rural Hospital in India

“…[3] They are usually solitary (90%-91%) and distributed unevenly throughout the head (50%-58%), body (24%-34%), and tail (16%-19%). [4] Hypothesis of hematogenous dissemination is considered to be the most common mode of spread to the pancreas. The other possible modes of spread are passage through the biliary system, lymphatic spread from the intestinal mucosa, direct spread through the pancreatic veins, and retroperitoneal dissemination.…”

“…The other possible modes of spread are passage through the biliary system, lymphatic spread from the intestinal mucosa, direct spread through the pancreatic veins, and retroperitoneal dissemination. [3,4] Most hydatid cysts are asymptomatic and diagnosis is incidental. Primary symptoms are abdominal pain, discomfort, and vomiting.…”

Causa rara de distensión abdominal aguda: apertura del conducto pancreático en un quiste hidatídico

“…Se informó quiste pancreático en 54 pacientes; entre ellos, el quiste se ubicaba en la cabeza del páncreas en 21 (38,8%), en la cola del páncreas en 18 (33,3%), en el cuerpo y la cola del páncreas en 8 (14,8%), en el cuerpo del páncreas en 5 (9,2%), en la cabeza y el cuerpo en uno, y en el cuello en otro. 10 Considerando que los quistes hidatídicos crecen con lentitud, la mayoría de los pacientes afectados no presenta síntomas durante años. Sin embargo, en los pacientes sintomáticos, los síntomas varían y dependen de la localización, el tamaño y la posición respecto de los órganos vecinos.…”

Isolated hydatid cyst of the pancreas masquerading as pancreatic pseudocyst

“…We had not performed a serological test initially as we had not considered hydatid in the differential diagnosis. The serological tests used commonly for the diagnosis of hydatid cysts are ELISA, indirect haemagglutination, serum immunoelectrophoresis, complement fixation test and immunofluorescence assay 7. ELISA gives positive results in about 85% of cases 8…”
