Neoplastic Lumbosacral Plexopathy in Untreated Cervical Cancer: A Case Report

초록

In this report, we present the case of a patient with cervical adenocarcinoma with progressive right lower-extremity pain and weakness. Electromyography of the lower extremities and subsequent ultrasonographic imaging complementarily demonstrated findings considered suspicious for the perineural spread of malignancy to the lumbosacral plexus and sciatic nerve. This possibility was confirmed by magnetic resonance imaging (MRI) and fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) scanning. This case report suggests that in addition to MRI and FDG PET/CT scans, electromyography and ultrasonographic imaging are valuable modalities for the diagnosis of perineural malignancy.
