Intradural invasion of lumbar synovial cyst. Case report.

A 63-year-old female presented with a rare case of synovial cyst invading the dura mater and mimicking an intradural extramedullary tumor in the lumbar spine. She underwent posterior lumbar fusion with laminar wire fixation from L3 to S1 levels. She complained of severe pain along the anterolateral thigh in both legs for 1 year.

Butterfly vertebra with lumbar intervertebral disc herniation.

A butterfly vertebra is a rare congenital anomaly that is usually asymptomatic. The authors, however, describe a novel case involving a butterfly vertebra overlapping with disc herniation that presented as radiculopathy. A butterfly vertebra is characterized by a symmetrical fusion defect resulting in a sagittal cleft vertebra.

Radiological findings of spinal schwannomas and meningiomas: focus on discrimination of two disease entities.

This study evaluates the effectiveness of CT and MR imaging in differentiating intradural extramedullary spinal schwannomas and meningiomas in a large group of patients. In addition, the study correlates tumour location, morphologic characteristics and enhancement pattern. From January 2000 to June 2007, we retrospectively reviewed 128 consecutive patients (51 male, 77 female; mean age at admission 53.

Midterm results of percutaneous CT-guided aspiration of symptomatic lumbar discal cysts.

Objective: Lumbar intervertebral discal cysts are rarely reported. To our knowledge, only 12 cases have been reported in the literature. The symptoms are indistinguishable from those of typical discal herniation.

Pure epidural cavernous hemangioma of the cervical spine that presented with an acute sensory deficit caused by hemorrhage.

Pure epidural cavernous hemangioma of the spine without vertebral involvement is rare. Due to the slow growth of this lesion, the most common symptoms are chronic pain, myelopathy, and radiculopathy. In our case, the patient complained of an acute onset sensory deficit of the C4 dermatome.
