Congenital absence of the pericardium is a rare condition,which is frequently missed due its subtle presentation. It may be misdiagnosed as another condition causing right heart dilatation such as an intracardiac shunt. We report the finding of diastolic pressure alternans during cardiac catheterization in this single case report of a patient with congenital total absence of the pericardium. The occurrence of this phenomenon is hypothesized to be due to excessive cardiac hypermobility and paradoxical septal movement. We propose that this finding may be a useful clue to the diagnosis.
Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas present more commonly in the elderly. This report describes a case of IPMN in a 36-year-old man who presented with obstructive jaundice and weight loss. The initial investigation by computed tomography scan revealed a cystic lesion in the head of pancreas fistulating into the duodenum and the common bile duct (CBD). Subsequent endoscopic retrograde cholangiopancreatography revealed a low CBD stricture with proximal filling defects. Mucin was observed extruding from the biliary orifice following an endoscopic sphincterotomy. A classic Whipple's pancreatoduodenectomy was performed to excise the lesion. A histological examination of the lesion confirmed the presence of a malignant IPMN of the pancreas complicated by pancreatobiliary and pancreatoduodenal fistulae.
We report a case of visceral pentastomiasis caused by Armillifer moniliformis in a 70-year-old aboriginal farmer from rural Malaysian Borneo. The patient complained of upper abdominal pain, jaundice, and loss of weight. Radiological investigations and subsequent histopathological examination revealed an adenocarcinoma of the pancreas with an adjacent liver nodule containing a nymph of A. moniliformis. This report constitutes the first documented human pentastomid infection in the whole of Malaysia after nearly 40 years, and it is the third description from Malaysian Borneo. Cases of human and animal pentastomiasis in Malaysia are discussed.
Small cell lung carcinoma (SCLC) commonly metastasizes to distant organs. However, metastasis to the pancreas is not a common event. Moreover, obstructive jaundice as a first clinical presentation of SCLC is extremely unusual. This case reports a 51-year-old male with SCLC, manifesting with obstructive jaundice as the initial clinical presentation. Endoscopic retrograde cholangiopancreatograghy (ERCP) and abdominal computed tomography (CT) scan showed a mass at the head of the pancreas. The patient underwent pancreatoduodenectomy (Whipple procedure). Histopathology revealed a chromogranin- A-positive poorly-differentiated neuroendocrine carcinoma of the pancreas. No imaging study of the lung was performed before surgery. A few months later, a follow-up CT revealed unilateral lung nodules with ipsilateral hilar nodes. A lung biopsy was done and histopathology reported a TTF- 1-positive, chromogranin A-positive, small cell carcinoma of the lung. On review, the pancreatic tumour was also TTF-1-positive. He was then treated with combination chemotherapy (cisplatin, etoposide). These findings highlight that presentation of a mass at the head of pancreas could be a manifestation of a metastatic tumour from elsewhere such as the lung, and thorough investigations should be performed before metastases can be ruled out.
Intussusception is common cause of bowel obstruction in the paediatric age group compared to the elderly population. Many times, the diagnosis may be difficult because of asymptomatic nature of this bowel disorder. We hereby describe the case of a 75-year-old male who presented with lethargy, weakness, loss of movement in the joints and was found to be anemic. The haemoglobin level was low so he was transfused with packed cells. On gastrointestinal (GI) endoscopy, upper GI bleed was observed. A mass was observed beyond ampulla at the 2nd and 3rd part of the duodenal junction. Computerized tomography (CT) scan also showed a mass at the head of pancreas and the lesion at the left lung. In view of persistent bleed, 'Whipple's procedure' was performed. Histopathological examination showed small cell carcinoma of the lungs with metastasis to the pancreas and the jejunum. We here discuss the case of intussusception with intestinal metastasis which presented with gastrointestinal bleeding.
