A very rare case of lingular sequestration.

Pulmonary sequestration also called as bronchopulmonary sequestration is a rare congenital anomaly. It is defined as a mass of dysplastic lung tissue which has no connection with the main bronchopulmonary tree and is supplied by a branch of systemic artery and drainage by the separate venous system. It can be classified into intralobar and extralobar variety, with intralobar being more common. Its incidence is around 1 per 8300 to 35000, and it constitutes about 0.15-6.4% of all congenital lung anomalies. It generally involves lower lobes with the left lobe being more common than the right. It is an uncommon entity and rarely reported in literature for lingula. Its distribution is equal in gender distribution except for extralobar variety which has a male preponderance. It generally presents with recurrent pneumonia and hemoptysis. Here, we describe a very rare case of intralobar lingular sequestration in a patient who presented with recurrent chest infections and was managed with segmentectomy.
