Lateral meningocele is a very rare disorder of unknown aetiology typified by the presence of protrusions of the arachnoid and the dura matter extending laterally through inter- or intra-vertebral foramina. We report here the case of a 52-year old male with abnormality of spine when presented with low back pain. The patient did not appear to have any neurological disorder. A computerized tomography (CT) scan was acquired from T12 to mid sacrum with multiplanar reformations. The results showed the presence of a left sided paraspinal cystic lesion projecting from the left neural foramen and extending into the left psoas muscle suggesting a lateral meningocele. In addition, a broad based central and left paracentral disc protrusion was also observed resulting in asymmetric canal stenosis. The patient is on regular follow-up while undergoing palliative treatment.
