Large anterior mediastinal mass by CT scan of the chest. Case: a 65-year-old female with an 8.7-cm anterior mediastinal mass. Diagnostic evaluation revealed absence of acetylcholine receptor antibodies and normal beta-HCG and AFP levels. A robotic resection of the mediastinal mass was performed via the left chest. The pleura anterior to the mass was dissected, mobilizing the mass into the right pleural space, while moving cephalad to the level of the innominate vein. The left and right horns were dissected. Visualization and protection of the left (not involved with the mass) and right phrenic nerves was assured. Two inferior port sites were consolidated into one incision to extirpate the mass. Pathology demonstrated a type AB thymoma, 9.5 cm in diameter. CT, computed tomography; HCG, human chorionic gonadotropin; AFP, alpha-fetoprotein.
