Extralobar pulmonary sequestration with an unusual venous drainage to the portal vein: preoperative diagnosis and excision by video-assisted thoracoscopy.

Pulmonary sequestration is an uncommon congenital malformation of the lung that can be classified as intralobar or extralobar (ELS). Approximately 90% of ELS occur in the left hemithorax. Approximately 10% of ELS may present below the diaphragm. Both types of sequestrations are characterized by pulmonary tissue that does not communicate with the bronchial tree. The arterial blood supply to 80% ELS is through a direct branch of the thoracic or abdominal aorta, in 15% via another systemic artery and 5% from the pulmonary artery. The venous drainage of ELS is variable, predominantly into the systemic circulation (via the azygos vein, hemiazygos vein, or inferior vena cava). Approximately 25% drain completely or partially through the pulmonary veins. We report an extremely rare case of ELS with unusual venous drainage to the portal vein.

Intrauterine intussusception: a rare cause of intestinal atresia.

Intrauterine intussusception is an uncommon cause of intestinal atresia. We report a case of ileal atresia owing to antenatal intussusception revealed as an intraluminal polypoid lesion after surgical intervention.

Double cervical cyst derived from a single thyroglossal duct tract.

Thyroglossal duct cysts are one of the most common congenital cervical pathologic findings in children. This type of cyst can be located anywhere between the base of the tongue and the sternal manubrium. We report the case of a patient with a double thyroglossal cyst, one located in the hyoid region and the other in the thyroid gland. The 2 cysts were connected by a permeable tract, which confirms that an involution failure of the embryonic remains of the thyroglossal duct was responsible for the development of the cyst. Intrathyroid cysts of the thyroglossal duct, though uncommon, should be included in the differential diagnosis of thyroid cysts in children.
