Abstract

BACKGROUND

Hydatid cyst of the pancreas is rare, accounting for less than 1% of the various sites of hydatid disease, even in countries where echinococcosis is endemic. We report a case of pancreatic hydatid cyst to increase awareness for this important condition.

CASE REPORT

We describe a 33-year-old male with abdominal discomfort of one-year duration. On abdominal examination, there was mild tenderness with fullness in the right upper quadrant. Laboratory investigations revealed no abnormalities. Abdominal ultrasonography showed a cystic mass over the head of the pancreas. Abdominal CT scan confirmed the presence of a solitary cyst in the pancreatic head, with no enhancement on contrast CT. Indirect hemagglutination test for hydatid disease was negative. A pre-operative diagnosis of cystic neoplasm of the pancreas was made and laparotomy was done; on exploration there was a cystic mass arising from the head of the pancreas. A pericystectomy was carried out and the diagnosis of hydatid cyst of the pancreas was confirmed by histopathology. The postoperative period was uneventful and no recurrence was seen after 2 years of follow-up.

CONCLUSION

Pancreatic hydatidosis, though very rare, should be considered in the differential diagnosis of pancreatic cystic lesions in the appropriate epidaemiological setting.

摘要

背景

胰腺包虫囊肿较为罕见,在包虫病流行的国家,其在包虫病各个发病部位中所占比例不到1%。我们报告一例胰腺包虫囊肿病例,以提高对这一重要病症的认识。

病例报告

我们描述了一名33岁男性,有长达一年的腹部不适症状。腹部检查时,右上腹有轻度压痛和饱满感。实验室检查未发现异常。腹部超声显示胰腺头部有一个囊性肿块。腹部CT扫描证实胰腺头部存在一个孤立性囊肿,增强CT扫描未见强化。包虫病间接血凝试验为阴性。术前诊断为胰腺囊性肿瘤,遂行剖腹手术;术中探查发现一个源于胰腺头部的囊性肿块。进行了囊肿外膜切除术,组织病理学检查确诊为胰腺包虫囊肿。术后恢复顺利,随访2年未见复发。

结论

在适当的流行病学背景下,胰腺包虫病虽极为罕见,但在胰腺囊性病变的鉴别诊断中应予以考虑。
