Splenic metastases in the course of neuroendocrine tumors – Are they really that uncommon?

#4214

Introduction: Splenic metastases are described as exceptional in the literature. Their frequency is low regardless of the type of neoplasm. In the course of neuroendocrine tumors (NETs), spleen involvement seems infrequent too. There is only a limited number of case reports of such presentation.

Aim(s): The study aimed to analyse the frequency and clinical presentation of spleen metastases in a group of patients followed in a single center.

Materials and methods: The studied group included 148 patients with G1 and G2 NETs originating from the gastro-entero-pancreatic and bronchopulmonary tract. All of these patients were diagnosed with locally advanced or metastatic disease and were included in the treatment with medical therapy. Splenic metastases were diagnosed on the basis of CT and/or MRI.
