Mediastinal and Other Neoplasms Flashcards
4 lab tests to order in indeterminate anterior mediastinal tumors
- Anti-acetylcholine receptor antibody (Thymoma and myesthenia)
- Alpha-fetoprotien (Non-seminoma germ cell tumor)
- Beta-HCG (Non-seminoma germ cell tumor)
- LDH (Germ cell and lymphomas
Most common mediastinal lesions regardless of compartment
- Thymoma (anterior)
- Neurogenic neoplasm (posterior)
- Lymphomas (anterior/middle)
- Metastases (anterior/middle)
4 T’s of anterior mediastinal tumors
- Thymoma
- “Terrible” tumors (lymphoma and metastasis)
- Teratomas (or any germ cell tumor but 2/3 are teratoma)
- Thyroid (intrathoracic thyroid specifically)
Disease associated with thymomas
Myesthenia Gravis
Most common lymphoma that is primary mediastinal
Nodular sclerosing hodgkins lymphoma
Preferred biopsy method for thymoma
Surgical resection
Theoretical chance of seeding with core needle biopsy
most aggressive type of germ cell tumor in mediastinum
Non seminomatous
AFP and beta-HCG elevated in which germ cell tumor of mediastinum
Non-seminomatous
Treatment for seminomatous germ cell tumors
Radiation and/or chemo
Treatment for non-seminomatous germ cell tumors of mediastinum
cisplatin based combination chemotherapy
resection of residual tumor
Bronchogenic cyst in middle mediastinum
Pericardial cyst middle mediastinum
mediastinal lymphangioma
Benign but can infiltrate
Mediastinal lipomatosis
3 posterior mediastinum tumors
- Neurogenic neoplasms
- Esophageal lesions
- Miscellaneous
