Synovial cyst--an unusual cause of nerve root compression. A case report. 1988

Department of Orthopaedic Surgery, University of Natal, Durban.

An elderly woman presented with a tense, synovia-lined ganglion, associated with the left L3/L4 apophyseal joint, which protruded posteriorly and caudally through the joint capsule and extended anteriorly and cephally into the neural canal. The intraspinal extension produced a compression radiculopathy of the L3 nerve root. Removal of the cyst produced acute and dramatic alleviation of the symptoms.

UI	MeSH Term	Description	Entries
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009408	Nerve Compression Syndromes	Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.

D013126	Spinal Nerve Roots	Paired bundles of NERVE FIBERS entering and leaving the SPINAL CORD at each segment. The dorsal and ventral nerve roots join to form the mixed segmental spinal nerves. The dorsal roots are generally afferent, formed by the central projections of the spinal (dorsal root) ganglia sensory cells, and the ventral roots are efferent, comprising the axons of spinal motor and PREGANGLIONIC AUTONOMIC FIBERS.

D013581	Synovial Cyst	Non-neoplastic tumor-like lesions at joints, developed from the SYNOVIAL MEMBRANE of a joint through the JOINT CAPSULE into the periarticular tissues. They are filled with SYNOVIAL FLUID with a smooth and translucent appearance. A synovial cyst can develop from any joint, but most commonly at the back of the knee, where it is known as POPLITEAL CYST.	Synovial Cysts,Cyst, Synovial,Cysts, Synovial
