Background:

Paratesticular paragangliomas are rare neuroendocrine tumors originating from ectopic or intra-abdominal paraganglia near the testis.
These tumors are often benign but can exhibit malignant behavior, including metastasis.

Observation:

A 43-year-old male presented with neurological deficits, including paresthesia and paraparesis.
Radiographic evaluation revealed a pathologic fracture of the D1 vertebra.

Findings:

The D1 vertebral fracture was identified as a metastasis from a previously undiagnosed, nonsecretory right paratesticular paraganglioma.
This represents an unusual presentation of metastatic disease from this rare tumor type.

Implications:

This case underscores the importance of considering rare tumors like paratesticular paragangliomas in the differential diagnosis of unexplained pathologic fractures and spinal metastases.
Early recognition and diagnosis are crucial for appropriate management and improved patient outcomes.
Further research into the metastatic potential and clinical behavior of nonsecretory paratesticular paragangliomas is warranted.
