Sciatica Caused by Perineural Spread of Prostate Cancer

Area of Science:

• Oncology
• Neurology
• Radiology

Background:

• Prostate cancer is a common malignancy in older men.
• Sciatica is a debilitating condition characterized by pain radiating along the path of the sciatic nerve.
• Surgical interventions for spinal conditions can sometimes lead to complications or diagnostic challenges.

Observation:

• An 81-year-old male patient with a history of prostate cancer presented with sciatica.
• Initial surgical treatment for suspected spinal stenosis (L4/5 laminectomy and L5/S1 fusion) provided temporary pain relief, followed by symptom recurrence.
• Enhanced magnetic resonance imaging (MRI) revealed a mass near the sciatic nerve, prompting surgical resection.

Findings:

• Histopathological examination confirmed perineural spread of prostate cancer to the sciatic nerve.
• This case highlights the potential for prostate cancer to infiltrate neural structures.
• The findings underscore the importance of considering metastatic disease in patients with recurrent or refractory sciatica.

Implications:

• Diagnostic imaging, particularly MRI, plays a critical role in identifying perineural spread of prostate cancer.
• Early and accurate diagnosis of perineural spread is essential for appropriate treatment and management.
• This case emphasizes the need for a multidisciplinary approach involving oncologists, neurologists, and radiologists in managing complex cases of cancer recurrence and neurological symptoms.
