An adult with central cyanosis and differential pulmonary vascularity

A 22-year-old male patient presented with progressive effort intolerance of 2-years duration. Clinical findings and investigations were suggestive of Tetralogy of Fallot (TOF). In addition, there was a conspicuous difference in the pulmonary vascularity with oligemia on the left side and relative hypervascularity on the right side. The right pulmonary artery was arising from the proximal ascending aorta and the main pulmonary artery was continuing as the left pulmonary artery. The anomalous origin of a branch pulmonary artery from the aorta (AOPA) is a rare cardiac anomaly. We report this condition in association with TOF, highlighting the differential pulmonary vascularity

Hydatid cyst of lung: An uncommon cause of chest pain in young

Echinococcosis can involve any organ. The liver is the most common organ involved, followed by the lungs. Depending on the location of involvement it can have varied presentation. We describe a young adult presenting with chest pain secondary to a pulmonary giant hydatid cyst. A pulmonary hydatid cyst should be considered in the differential diagnosis of patients presenting with chest pain without conventional risk factors of coronary artery disease, especially in a tropical region
