Neuroendocrine tumor presenting like lymphoma: A case report

Abstract

Introduction. Neuroendocrine tumors are a rare but diverse group of malignancies that arise in a wide range of organ systems, including the mediastinum. 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 middle-posterior 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. © 2011 Del Vescovo et al; licensee BioMed Central Ltd.
