Abstract

Thymic cyts that are located in the mediastinal space are rarely seen and forms 1-3% of all the mediastinal masses. They may be congenital or acquired. During the coronary artery surgery of 54 years old male patient, 14x4 cm and 13x3 cm sized masses were detected at the anterior mediastinum. The masses were thick walled and had multicystic apperance. After the median sternotomy, all thymic cysts were resected then coronary artery bypass surgery was performed. The histopathologic examination was diagnosed as acquired multilocular thymic cysts and lymhoid hyperplasia. Thymic masses can be accidentally seen during median sternotomy for coronary artery bypass surgery, we think that removal of these masses are necessary and beneficial.

Koroner arter bypass operasyonu sırasında rastlanılan multiloküler timik kist

Abstract

Mediastinal yerleşimli timik kistler nadir olup, tüm mediasten kitlelerinin %1-3\'ünü oluşturur. Kistler doğuştan veya akkiz olabilir. Koroner arter hastalığı tanısıyla operasyonu yapılan 54 yaşındaki erkek hastada cerrahi işlem sırasında 14x4 cm ve 13x3 cm boyutunda iki adet anterior mediastinal kitle saptandı. Kitleler, kalın duvarlı ve multipl kistik görünümdeydi. Median sternotomi sonrası her iki timik yapı tümüyle çıkarıldıktan sonra hastaya koroner arter bypass operasyonu uygulandı. Histopatolojik incelemede edinsel multiloküler timik kist ve lenfoid hiperplazi tanısı kondu. Koroner arter bypass operasyonu için yapılan sternotomide timik kistlerle karşılaşıldığında, kitle eksizyonunun yararlı ve gerekli olduğu kanaatindeyiz.
