ABSTRACT

Vascular injuries from penetrating trauma to the base of the neck are accompanied by significant morbidity and potential mortality. These injuries require several diagnostic adjuncts in order to facilitate early diagnosis and appropriate treatment. Herein reported is the case of a patient who sustained penetrating injury to the thoracic inlet but had a fortuitous anomaly that prevented vascular injury and its attendant complications.

ABSTRACT

Mirror image transposition of abdominal and thoracic viscera is termed situs inversus. Duodenal obstruction in situs inversus is rare. A preduodenal portal vein, though not uncommon in situs inversus, rarely causes duodenal obstruction. Where obstruction by a preduodenal portal vein is diagnosed, a duodeno-duodenostomy is the recommended treatment. A duodenal diaphragm and other more common causes of duodenal obstruction should also be excluded in these patients.

Carcinoid tumours have been reported in a wide range of organs but most frequently involve the gastrointestinal tract. Many of these carcinoid tumours are associated with metachronous and synchronous lesions of another histological type. Primary carcinoid tumours of the different organ in the same patient is rare. In this paper, the authors present a case with synchronous carcinoid tumour of the small intestine and appendix in the same patient.

ABSTRACT

Herein reported is the case of a young woman who had hyperinsulinaemic hypoglycaemia which was biochemically consistent with an insulinoma. Initial imaging was negative and definitive treatment was delayed until repeat imaging localized the tumour several years later. This case demonstrates the importance of clinical judgment and biochemical testing in the diagnosis of insulinoma despite negative imaging.
