Peripheral neuropathy sciatica is classified as a pseudo-sciatica which mimics traditional sciatic nerve pain. While true sciatica occurs from problems affecting the spinal nerve root sources of the sciatic nerve, peripheral neuropathy sciatica stems from the smaller nerves which branch out throughout the body into the lower extremities. These nerves control the motor and sensory needs.

Superficial Siderosis patients report bilateral pain extending from the low back area down the back of both legs. This pain may be intermittent but is known to progress to a chronic state.

Sources: Superficial siderosis is a rare neurologic disease characterized by progressive sensorineural hearing loss, cerebellar ataxia, pyramidal signs, and neuroimaging findings revealing hemosiderin deposits in the spinal and cranial leptomeninges and subpial layer. The disease progresses slowly, and patients may present with mild cognitive impairment, nystagmus, dysmetria, spasticity, dysdiadochokinesia, dysarthria, hyperreflexia, and Babinski signs. Additional features reported include dementia, urinary incontinence, anosmia, ageusia, and anisocoria. Superficial siderosis MedGen UID: 831707 •Concept ID: CN226971 •Finding Orphanet: ORPHA247245
