Five patients presenting with sensory-motor disturbances consistent with a clinical diagnosis of L5 or S1 radiculopathy were studied. All had conventional nerve conduction tests and electromyography. The lumbosacral roots were stimulated in the lumbosacral region by using the Cadwell MES-10 Magneto-electric stimulator. The compound muscle action potentials were recorded bilaterally by surface e...

We describe the case of a 39-year-old woman with signs and symptoms suggesting cauda equina syndrome. Lumbosacral magnetic resonance imaging (MRI) demonstrated no lesion at this level, while cervical MRI showed a T2-hyperintense lesion in the middle-right anterolateral region of the cervical spinal cord, which may explain the symptoms by involving the anterior spinothalamic tract. We suggest th...

A 26-year-old man, previously healthy, presented with a 6-month history of bilateral sciatic pain and frequent constipation but no urinary symptoms. Physical examination revealed tenderness of the lumbosacral region with radiating pain along the sciatic nerve and the perinea without motor weakness of the inferior legs. No cutaneous lesions were noted especially no café-au-lait macules. Magnetic...

Meningoradiculitis refers to combined involvement of meninges and nerve roots. The most frequent location is the lumbosacral region. Etiology is diverse, including inflammatory, infectious and neoplastic disorders. Meningoradiculitis is a rare form of involvement in cryptococcal infection. We describe a case of subacute lower limbs flaccid paresis diagnosed as lumbosacral meningoradiculitis in ...

The most common lumbosacral mass of a fetus is a meningomyelocele that is not covered by skin; however, skin-covered lesions do occur, and they often have a quite different clinical cause and outcome. It is often difficult to make this differentiation on ultrasonography; when a skin-covered mass in the lumbosacral region is encountered, the following differential diagnoses should be considered....

OBJECTIVE The etiology and pathology of pain in the lumbosacral region and pelvis of pregnant women during and after pregnancy have not been fully determined. This study evaluated if lower back pain during pregnancy and after childbirth is connected with static alterations in the alignment of the pelvis, dysfunction of sacroiliac joints, and irritation of the pelvic ligaments and spine in the l...

Much remains to be learned about the embryology and pathophysiology of the "tethered cord syndrome." Of particular importance in tethered cord syndrome is spinal cord stretchability and its relation to resultant cord dysfunction. In this study, cord elongation was observed in fresh fetuses and in animals by applying weights or forceps traction at the conus medullariscauda equina region. The res...
