Multilocular thymic cysts- a diagnostic challenge on computed tomography.

A recent case report provided a patient scenario, wherein, a 39-year-old male patient presented with occasional palpitations, headache, and fever. Evaluation of tumor markers did not show any abnormal results. Subsequently, a computed tomography (CT) scan was undertaken, and its findings were affirmative of thymic cancer. Finally, the postoperative histopathological assessment of the mass, after its resection, confirmed it as an anterior mediastinal multilocular thymic cyst (MTC), with concurrent acute upper respiratory tract infection and acute myocarditis. Accordingly, this case report advocates the need for a preoperative histopathological examination with CT imaging to minimize the risk of confusing an MTC with a malignant thymic tumor.
