Intracranial haemorrhage following lumbar myelography: case report and review of the literature.

We describe a subacute intracranial subdural haematoma following lumbar myelography. This rare but potentially life-threatening complication has been reported both after lumbar myelography and following lumbar puncture for spinal anaesthesia. We review 16 previously reported cases of intracranial haemorrhage following lumbar myelography, and discuss the pathogenesis. In all reported cases post-puncture headache was the leading symptom and should therefore be regarded as a warning sign.

[Severe and prolonged post-dural puncture headache: from pathological basis to therapeutic role and correct timing for epidural blood patch].

Believed to be due to unbalance between cerebrospinal fluid (CSF) production rate and its loss through the spinal dural puncture hole, post-dural puncture headache (PDPH) is often considered as a physiological syndrome, usually reversible without pathological sequelae after dural hole's closure. The clinical case here presented (incapacitating headache associated with diagnostic dural puncture in a leukaemic young female patient who underwent bone marrow transplantation) shows potentially fatal pathological sequelae following prolonged headache (untreated, due to the severe postransplant immunodeficiency and coagulopathy). The observed RMI lesions suggest interesting conclusions about the clinical indications and correct timing of autologous epidural blood patch (EBP). We also suggest the ways to preventing rebound intracranial hypertension following autologous epidural blood patch in patients suffering from incapacitating and prolonged headache.

Hydromyelia: clinical presentation and comparison of modalities of treatment.

The clinical and radiographic features of 60 cases of hydromyelia area discussed. A combination of motor and sensory symptoms and signs is the usual presentation, but pure motor or sensory forms of the disease are not infrequent. Pain and scoliosis are usually associated with a high degree of blockage. A normal spinal fluid protein content in the presence of an enlarged spinal cord is of diagnostic value. Important radiographic clues include widening of the spinal cord without venous stagnation and collapse of the spinal cord visualized with the patient in the upright position. Metrizamide computed tomography is now used routinely, and the contrast agent may at times appear in the dilated central spinal canal. Decompression of the foramen magnum is the treatment of choice in the presence of an associated Arnold-Chiari malformation and is the treatment most likely to succeed. In selected cases, decompressive laminectomy and syringostomy may be indicated. Percutaneous spinal cord puncture is a safe diagnostic-therapeutic procedure which, surprisingly, may afford relief equal to that of more drastic measures. Therefore, percutaneous spinal cord puncture may be an option of therapeutic value in a disorder that is frustrating to treat.

[Proton spin tomography in childhood. Experience with 407 studies in 275 children and adolescents].

Over a period of three years magnetic resonance imaging (MRI), mostly neuroradiological, was performed 407 times in 275 children. It was found that MRI largely replaced previously applied imaging methods for solving oncological and neurological problems. The sensitivity of the method is poor for demonstrating small calcifications (computed tomography is better), for diffuse meningeal lesions (lumbar puncture is better), and diffuse spinal-canal metastases (myelography is better). The great advantage of the method lies in its low x-ray exposure because of the low field strength, and it can therefore be safely used repeatedly.
