Use of Spermatic Cord Block Systematically Identifies a Paraspinal Tumor as Source of Orchialgia.

Abstract

Orchialgia is a common urologic complaint with a myriad of etiologies. Workup for orchialgia requires a broad differential diagnosis and a thorough understanding of relevant anatomy. We report the case of a 43-year-old man who presented to a urologist with right testicular pain. Following a negative workup, the patient received a spermatic cord block for therapeutic and diagnostic purposes. Two months after the block, the patient returned with new complaints of ipsilateral inner thigh paresthesias, suggesting a pathologic process proximal to the genital branch of the genitofemoral nerve. A subsequent MRI of the lumbosacral spine revealed a paraspinal mass involving nerve roots at L1-2. We highlight the utility of the spermatic cord block and its role in the diagnosis of a paraspinal tumor as an uncommon cause of orchialgia.
