Mediastinal Tumors

These rare tumors, affecting under 1% of people, divide by location: anterior (50%, e.g., thymomas, lymphomas), middle (e.g., cysts), and posterior (neurogenic in children). Adults typically see anterior masses, many cancerous like thymic carcinoma or Hodgkin lymphoma; children favor benign nerve tumors. Risk factors remain unclear, though some link to genetic or autoimmune conditions.?

Symptoms and Diagnosis

Up to half are asymptomatic, found incidentally on chest X-rays. When symptomatic, compression causes cough, shortness of breath, chest pain, hoarseness, hemoptysis, fever, night sweats, or weight loss. Diagnosis uses CT/MRI scans, biopsy via mediastinoscopy, and blood markers like AFP for germ cell tumors.?

Treatment Approaches

Benign tumors often require surgical removal; malignant ones use chemotherapy, radiation, or targeted therapy based on type (e.g., rituximab for lymphomas). Prognosis excels for resectable thymomas (80-90% 5-year survival) but varies for aggressive cancers. Multidisciplinary care improves outcomes.
