[Giant thoracolumbar synovial cyst: case report].
METHODS
A case report of a giant thoracolumbar synovial cyst is presented.


RESULTS
A 74-year-old woman presented with a chronic lumbar pain associated with pain in the left leg. MR imaging showed a voluminous extradural cyst extending from T12 to L2. The cyst was surgically removed entirely. Microscopic examination revealed a synovial cyst.


CONCLUSIONS
In spite of a careful review of the literature, no other description of a giant thoracolumbar synovial cyst developed on three metameric levels was found. The diagnosis was made with a MRI scan combined with microscopic examination. The pathogenesis and therapeutic strategy are discussed.
