Ectopic colloid goiter in mediastinum with normal thyroid gland.

Ectopic thyroid tissue is a rare developmental abnormality involving aberrant embryogenesis of the thyroid gland during passage from the primitive foregut to the pretracheal position. The most frequent position is the base of the tongue (lingual thyroid); however, it has been described in other sites, such as the submandibular region, trachea, mediastinum, and subdiaphragmatic regions.Here, we report a case of an adenomatous goiter that developed in mediastinal thyroid tissue without any connection to the pretracheal thyroid gland.

An Unusual Case of Biliary Stent Migration in Sacrum.

The common bile duct stenting has been a common endoscopic procedure practiced worldwide for the treatment of benign or malignant bile duct obstruction. Although the procedure has shown a very low morbidity, it is not free from complications. Stent migration has been a common late complication seen in 10% of cases presenting with various manifestations depending on the site of impaction. Here, we present a rare case of distal stent migration with impaction in the sacral foramina due to perforation through sigmoid diverticula with review of literature.
