Multilocular thymic cysts, preoperative diagnosis and treatment: a clinical case

Biopsy has limited value and is relatively effective only against cystic tumors for preoperative diagnosis of mediastinal cysts. Noninvasive clinical imaging is relevant here, taking into account the localization of the neoplasm and its relationship to neighboring structures. Non-tumor cysts of the thymus gland (CTG) are divided into monolocular (congenital, primary) and multilocular (acquired, secondary). A clinical case of a 45-year-old woman with a multilocular CTG diagnosed by computed tomography and videothoracoscopically removed is presented. The issues of diagnosis and differential diagnosis of multilocular CTG and their possible connection with COVID 19 are discussed.
