INTRODUCTION: @entity5 or paraganglia are extremely rare and present a diagnostic dilemma. These @entity5 consist of a neuroendocrine component mixed with a neural component.We describe the imaging characteristics together with the corresponding pathological findings of a composite @entity5 . Apart from any component-specific imaging findings, the hallmark of this entity is the presence of histologically distinguishable components. CASE PRESENTATION: A 61-year-old Caucasian @entity1 was referred to our hospital due to a suspect lesion found on chest computed tomography carried out for unclear @entity158 . An abdominal computed tomography scan and ultrasound examination detected a retroperitoneal @entity5 comprising two different @entity5 components. Twenty-four-hour urine revealed high levels of @entity6531 , characteristic of a @entity5 . An octreoscan prior to surgical procedures revealed @entity99 . The final histopathological workup revealed a composite @entity1823 with @entity521 . Our @entity1 died ten months after the initial diagnosis from @entity5 . CONCLUSIONS: Composite @entity1823 with @entity521 are rare @entity5 of the retroperitoneum. @entity5 should be considered in the differential diagnosis of retroperitoneal masses.
