A unique case of a giant anterior mediastinal teratoma extending into the right hemithorax in an adult female: A case report study

Introduction and significance: Teratomas are rare tumors, some of which have a benign growth pattern. Symptoms can vary depending on their size and location, usually becoming noticeable when they reach a large size. CT scans are effective in detecting these tumors and their surrounding connections. Case presentation: We present the case of a female who experienced a brief period of fatigue at work. Further investigation revealed the presence of significantly enlarged mature teratomas. Surgical resection successfully improved and saved the lung. Clinical discussion: When there is suspicion of a teratoma or a large mediastinal mass, it is important to opt for surgical intervention rather than subjecting the patient to the anesthetic risk associated with attempting a biopsy. Conclusion: In cases of large mediastinal and thoracic masses, complete resection should be pursued when feasible, as the majority of mediastinal teratomas are benign. Complete resection usually leads to excellent results and a good prognosis.
