Diagnostic Differentiation and Imaging Recommendations for Deep Gluteal Syndrome

Clinical Differentiation from Lumbar Radiculopathy

• Deep gluteal syndrome (DGS) is distinguished from lumbar radiculopathy by the absence of a positive straight‑leg raise (typically 30–70°), lack of dermatomal sensory loss, no focal muscle weakness in a nerve‑root distribution, and preserved deep‑tendon reflexes; these findings help exclude spinal pathology and support a diagnosis of DGS. 1

Imaging Guidelines

• The American College of Radiology (ACR) Appropriateness Criteria state that routine imaging for uncomplicated low‑back pain without red‑flag features is not beneficial; however, in suspected DGS imaging—specifically pelvic MRI—should be performed to locate the entrapment site and to rule out discogenic causes. 2

Pharmacologic Management

• Non‑steroidal anti‑inflammatory drugs (NSAIDs) are recommended for pain control in DGS patients when there are no contraindications. 3

Interpretation of MRI Findings

• Incidental MRI abnormalities are frequently observed in asymptomatic individuals; therefore, a diagnosis of DGS requires correlation of imaging results with the clinical examination rather than reliance on imaging alone. 4
