Rarer Components of a Rare Disease: Accessory Hemidiaphragm and Horseshoe Lung with Scimitar Syndrome; Two Case Reports

Abstract

Introduction: Scimitar syndrome is a rare developmental anomaly with an incidence of 2/100.000 births. Major components of this disease are partial anomalous pulmonary venous drainage, pulmonary hypoplasia, systemic arterialization of the right basal lung, and dextroposition of the heart. Horseshoe lung and accessory hemidiaphragm are two rarer components of this disease.

Case presentation: In this paper, horseshoe lung and accessory diaphragm associated with Scimitar syndrome have been reported in two cases.

Conclusion: In conclusion, being aware of rare manifestations of rare diseases is important to fully describe the pathologic spectrum of the disease. This will assist in better management and decision-making process.

Keywords: Accessory diaphragma; Horseshoe lung; Scimitar syndrome; case report; pulmonary hypoplasia.
