Differential diagnosis includes other masses arising in the middle mediastinum such as lymphoma pericardial bronchogenic and enteric cysts metastatic tumors xanthogranuloma systemic granuloma diaphragmatic hernia meningocele and paravertebral abscess. Case presentation We present a case of 42-year-old Caucasian man with a neuroendocrine tumor of the middleposterior mediastinum and liver metastases which resembled a lymphoma on magnetic resonance imaging. Conclusion The differential diagnosis in patients with mediastinal masses and liver lesions should include neuroendocrine tumor. Introduction Neuroendocrine tumors NETs are a rare but diverse group of malignancies that arise in a wide range of organ systems. This can therefore include the mediastinum 1 2 . Differential diagnosis includes other masses arising in the middle and posterior mediastinum such as lymphoma pericardial bronchogenic and enteric cysts metastatic tumors xanthogranuloma systemic granuloma diaphragmatic hernia meningocele and paravertebral abscess. When a large mass is discovered pathological conditions of the anterior mediastinum such as thymoma germ cell tumors intrathoracic goiter lipoma lymphangioma and aortic aneurysm should also be considered 3 4 . We present a case of a NET of the middle-posterior mediastinum with liver metastases which resembled a lymphoma on magnetic resonance imaging MRI . Case presentation A 42-year-old Caucasian man was referred to our .
