Tarlov Cysts Masquerading as Peripheral Neuropathy

Arch Neurol. 2006;63(12):1804-1805. doi:10.1001/archneur.63.12.1804

A 43-year-old woman presented with paresthesia and numbness in her right foot. Three months later, the same symptoms appeared in her left foot and her gait started to become unsteady. She had occasional low back pain without any radicular pain or bladder symptoms. She was referred to the University of Chicago Neuropathy Center, Chicago, Ill, after being diagnosed with peripheral neuropathy.

Examination showed weakness of some of the right distal foot muscles. Vibratory sensation was mildly decreased at the toes; the pinprick and light touch sensations were diminished in the distal legs and feet, to a greater extent on the right. Ankle and knee reflexes were normal.
