Dextrocardia can be defined as a heart in the right chest with the major axis to the right. This definition, however, conveys no information regarding the chamber arrangements and internal anatomy of the heart. Of 40 patients satisfying this definition in the files of the Brompton Hospital, 33 had angiocardiographic data adequate for complete analysis in terms of connections, relations, and mor...

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 cau...

Polysplenia is a presence of two or more spleens in a patient and polysplenia syndrome refers to its association with various organ abnormalities in abdomen and chest. In about 20% cases of polysplenia syndrome situs inversus is present [1]. Polysplenia syndrome in association with situs inversus abdominus and intestinal atresia is rarely reported. We are presenting a case of polysplenia syndro...

Primary ciliary dyskinesia (PCD) is a genetically heterogeneous disorder associated with ciliary defects and situs inversus totalis, the complete mirror image reversal of internal organ situs (positioning). A variable incidence of heterotaxy, or irregular organ situs, also has been reported in PCD patients, but it is not known whether this is elicited by the PCD-causing genetic lesion. We studi...

Hellenic Journal of Nuclear Medicine ñ May August 2007 To the Editor: A 38 years old woman with a history of Hodgkin’s disease after a course of chemotherapy was referred to our PET/CT department to search for possible recurrent disease. After 6 h of fasting, her serum glucose level was 103 mg/dl and the patient was injected intravenously (i.v.) with 510,6 MBq of 18F-FDG. The patient was imaged...

Pitx2 is expressed in developing visceral organs on the left side and is implicated in left-right (LR) asymmetric organogenesis. The asymmetric expression of Pitx2 is controlled by an intronic enhancer (ASE) that contains multiple Foxh1-binding sites and an Nkx2-binding site. These binding sites are essential and sufficient for asymmetric enhancer activity and are evolutionarily conserved among...

Dextrocardia is a cardiac positional anomaly in which the heart is located in the right hemithorax with its base-to-apex axis directed to the right and caudad. Situs inversus is an autosomal recessive disorder that causes organs in the chest and abdomen to be positioned in a mirror image from their normal position. Dextrocardia may occur in isolation or as part of situs inversus. Similarly, sit...

Situs inversus totalis is a rare condition, which presents difficulties in diagnosis and treatment of gallstones due to the reversal location of abdominal organs. In this article we present 2 cases of women in age of 51 and 55 years with situs inversus totalis and gallstones. There are described the clinical and imaging features, also the laparoscopic surgery with the difficulties encountered b...

This report is to present and discuss an extremely rare association of situs inversus with duodenal atresia in an 11-day-old male neonate born full term and weighing 1.9 kg. The baby presented with recurrent bilious vomiting. Babygram revealed situs inversus and duodenal obstruction. Echocardiography showed dextrocardia with a small ASD. Exploration confirmed a duodenal diaphragm with a central...

Duodenal atresia is rarely associated with situs inversus abdominus. We report a case of duodenal atresia associated with small bowel atresia of apple peel type and situs inversus abdominus.
