Abstract:
Tarlov’s cyst is often underdiagnosed since it is difficult to identify without imaging assistance. Herein, we report the case of a young girl who presented with an 8-year history of chronic osteomyelitis of bilateral proximal phalanges and metatarsal bones caused by a Tarlov’s cyst that did not contain a nerve root. The chronic wound in the forefoot is an unusual presentation and resulted from the Tarlov’s cyst accompanied with tethered conus syndrome.

Tarlov’s cyst, also known as perineural cyst, is a cerebrospinal fluid-filled sac. It usually forms on the extradural component of sacrococcygeal nerve roots at the junction of dorsal root ganglion and posterior nerve roots [1], and it is often located at the S1 to S5 nerve root area causing corresponding radiculopathy, paresthesia, and muscular weakness. Most Tarlov’s cysts are asymptomatic until they become large enough to cause stretching or exert a compression effect on the nerve root, which is most commonly…
