Diagnosis With Brief Discussion

Diagnosis
Primary mediastinal choriocarcinoma
Radiologic Findings
A 27-year-old male patient presented with hemoptysis for 5 days. Chest CT image with mediastinal setting showed about 5 x 3 cm irregular shape necrotic mass in the anterior mediastinum. Chest CT images with lung window setting showed multiple nodules with surrounding ground glass opacities in both lungs. F-18 FDG PET/CT images show about 5 cm hypermetabolic mass with internal necrosis in anterior mediastinum, and multiple hypermetabolic nodules in both lung fields. Testicular ultrasonography showed no mass lesion. His alpha-fetoprotein level was 2.3 ng/mL (reference: 1.1–5.0 ng/mL). His beta-hCG level was 9164.0 mIU/mL (reference: 0–2.6 mIU/mL). Wedge resection was performed from the left upper lobe. The pleural surface of the specimen was smooth and glistening. On multiple cut sections, multiple solid, tan nodules were found. Pathological diagnosis revealed choriocarcinoma (figure).
Brief Review
Choriocarcinoma is a highly malignant tumor that originates from syncytiotrophoblasts. Primary choriocarcinoma of the mediastinum is defined as a choriocarcinoma in the mediastinum without a primary gonadal lesion or metastatic retroperitoneal lymph nodes. Primary choriocarcinoma of the mediastinum is extremely rare, and the diagnosis of the primary choriocarcinoma is challenging. Patients with primary choriocarcinoma are usually young men between 20 and 30 years of age. The main symptoms of primary mediastinal choriocarcinoma include dry cough, hemoptysis, gynecomastia, and chest pain. Chest computed tomography shows a large irregular shaped mass with central necrosis, hemorrhage, or cyst formation in the anterior mediastinum. Early hematogenous metastases to the lung, liver, and brain are common. Serological examination demonstrates a high beta-hCG level. The prognosis of primary mediastinal choriocarcinoma is poor even after combination chemotherapy.
