Colonic perforation due to impacted faeces or faecaloma is a relatively uncommon presentation with grave prognosis. If left untreated, it can be life threatening due to complications like faecal peritonitis. Till date, fewer than 150 cases have been reported mostly in the English surgical literature describing constipation as the most common underlying etiology. Involvement of rectum is rare with very limited data published in this context. We present a case of stercoral perforation involving the rectum with associated faecal peritonitis and pneumatosis coli.

Gas within the portal circulation has been known to be associated with a number of conditions most commonly mesenteric ischemia and necrosis. Systemic venous gas is described with few conditions and is mostly iatrogenic in nature. We describe a case of combined portal and systemic venous gas detected by computed tomography in a patient with perforated duodenal ulcer.

Fetal ovarian cysts are the most common abdominal masses in the female fetuses and believed to be caused by in utero exposure of fetus to maternal and placental hormones. Majority of them are diagnosed in third trimester and should be distinguished from other causes of abdominal masses of genitourinary and gastrointestinal origin. Once diagnosed serial ultrasound monitoring is recommended to document changes in size or appearance. Complications like torsion or rupture merit careful assessment and surgical intervention to preserve ovarian function and fertility. We report a case of intrauterine ovarian dermoid cyst complicated by torsion, which was diagnosed prenatally on ultrasound as complex cystic lesion within the abdomen.

Kommerell diverticulum is a rare developmental anomaly of aortic arch. It is most frequently seen with right-sided aortic arch and aberrant left subclavian artery or ligamentum arteriosum, which have a significant role in completing a vascular ring. However, aberrant origin of neck vessels along with it is not commonly seen. The signs and symptoms vary depending on the severity. The paediatric patients usually present early due to compression of mediastinal structures such as trachea or oesophagus.
