Rogers [6]	Sensory disturbance radiating to the anterior thighs upon cervical neck flexion.	Metastatic prostate carcinoma leading to spinal cord compression at T5.
Liveson and Zimmer [7]	Electric shock-like sensation radiating down the spine and occasionally into the toes upon trunk flexion.	Gibbus deformities of unknown cause at T6 and T7 with anterior extradural compression of the spinal cord.
Broager [8]	Sensation of intense paresthesia in both anterior thighs upon cervical flexion, accompanied by weakness and decreased sensation in the legs.	Metastatic prostate carcinoma leading to spontaneous T5 vertebral fracture.
