Diagnosis With Brief Discussion

Diagnosis
Mature cystic teratoma
Radiologic Findings
Chest radiograph shows well-defined bulge iing mass in left side cardiac contour. Chest precontrast CT shows well circumscribed heterogeneous density well-defined cystic mass, with smalsmall amount ofl fat content and amorphous calcification, located in anterior mediastinum, abutting left atrial appendage. Chest pPostcontrast CT shows no enhancement in the mass, suggesting cystic nature.
Brief Review
Mature cystic teratomas (dermoid cysts) are cystic tumors composed of well-differentiated derivations from at least two of the three germ cell layers (ectoderm, mesoderm, and endoderm). Mature cystic teratomas are the most common germ cell neoplasm. They occur more frequently in young adults. Most are asymptomatic and are incidentally discovered, but large tumors may cause chest pain, dyspnea, cough, or other symptoms of compression. The majority of dermoid cysts are in the anterior mediastinum, with only 3%–8% occurring in the posterior mediastinum.
At On radiography, cystic teratomas usually appear as a sharply marginated, rounded or lobulated anterior mediastinal mass that extends to one side of the midline. Calcification, ossification, or even teeth may be visible on chest radiographs. At On CT, these tumors are heterogeneous, well-defined masses with walls of variable thickness that may enhance. They may contain all four tissue types, including soft tissue, fluid, fat, and calcium, but fluid-containing cystic components are usually prominent. Calcifications may be focal, rim-like, or, in rare cases, representative of teeth or bone. A fat-fluid level within the mass is a highly specific finding but is seen less frequently.
