Presentation
Epigastric pain for the last 20 days. Serum amylase elevated.
Patient Data
CECT abdomen revealed acute on chronic calcific pancreatitis with peripancreatic fluid collections and pseudocyst in uncinate process of pancreas.
Incidental finding – wedge shaped area noted in left lower lobe of lung in left paravertebral location with arterial supply directly arising from the aorta – suggestive of intralobar pulmonary sequestration.
Case Discussion
Pulmonary sequestration is an area of non-functional lung tissue supplied by aberrant vessels and discontinuous with the tracheobronchial tree. They are of two types - intralobar (more common) and extralobar. Some of these patients are asymptomatic and are discovered incidentally. Surgical resection is the treatment of choice, as an intralobar type of sequestration can be associated with pneumonia or bronchial obstruction.
