Recurrent spinal echinococcosis

Alveolar echinococcosis presenting with simultaneous cerebral and spinal involvement.

A 37-year-old Tibetan shepherdess presented with headache and weakness of the lower limbs for 10 months. Examination disclosed a positive straight-leg-raising test. Neuroimaging showed a heterogeneous mass in the left temporal lobe (figure 1) and an intradural mass in the lumbosacral canal with L4 vertebral body destruction (figure 2). Chest and abdominal CT scans were negative. Two operations ...

Recurrent Facilitation of Spinal Reflexes

Antidromic volleys in muscle nerves may facilitate monosynaptic reflexes originating from neighboring motoneurons. This facilitation has been studied in spinal cats. It is at its peak with a conditioning-test interval of 20 to 30 msec., and can last 50 to 100 msec. The threshold of facilitation is about the same as that of recurrent inhibition. Both phenomena appear to be activated by stimulati...

Recurrent Conditioning in the Cat Spinal Cord

The action of cumulative doses of meprobamate on antidromic conditioning has been studied in spinal cats. Recurrent facilitation is greatly reduced or completely abolished by total doses ranging from 210 to 400 mg./kg. The depth of recurrent inhibition is not affected in a consistent manner by meprobamate, but the duration of inhibition is markedly increased in all experiments. This differentia...

Recurrent Spinal Meningioma: A Case Report

Meningiomas are the second most common intradural spinal tumors accounting for 25% of all spinal tumors. Being a slow growing and invariably benign tumor, it responds favorably to surgical excision. In addition, spinal meningioma has low recurrence rates. However, we experienced a case of intradural extramedullary spinal meningioma which recurred 16 years after the initial surgery on a 64-year-...
