Patients may be asymptomatic or have a significant morbidity depending on the species. Infection with Taenia species is sometimes found by expulsion of eggs or proglottids in stool. Species specific diagnosis of Taenia is difficult,but possible. We present a case of Taenia saginata incidentally discovered,and risk factors for transmission,diagnosis,symptoms,and treatment.展开更多

In human, tapeworm species can cause a parasitic infection by ingestion of raw or under cooked beef (<em>T. saginata</em>) or pork (<em>T. solium</em> and <em>T. asiatica</em>). Taeniasis usually presents with vague symptoms or mild abdominal pain and discomfort. The intestinal complications are not commonly mentioned in the literatures.<strong> Case presentation:</strong> We present 65-year-old Egyptian woman who lives in Oman, who is known to have type two diabetes mellitus and hypertension. She presented to Emergency department with abdominal pain and constipation for a period of three days. On examination, she was dehydrated with tachycardia (pulse rate: 110/minute) blood pressure of 100/60 mmHg and patient was afebrile. Abdominal examination revealed, mildly distended abdomen and tense, no guarding or rigidity no palpable mass, exaggerated bowel sound and rectum is empty on per rectal examination. Emergency laparotomy was performed with intra-operative findings of large foreign body impacted in the distal jejunum about 8 × 3 cm, cylinder in shape completely obliterating the lumen, distal loops was collapsed. <strong>Conclusion: </strong>Although Taeniasis is a very rare infection, index of suspicion such as a potential in the differential diagnosis as cause of an acute abdomen with unusual surgical complications should be considered. The diagnosis of these rare circumstances is usually made intraoperatively, and surgery is recommended only for the treatment of complications.展开更多
