Spontaneous intracranial hypotension: use of unenhanced MRI.

We report a case of spontaneous intracranial hypotension diagnosed with unenhanced cranial MRI, showing laminar subdural fluid and engorgement of the hypophysis and perisellar sinuses. Cerebrospinal fluid pressure was low. MRI was normal after resolution of symptoms. Prior reports emphasise the enhancing pachymeninges seen in this syndrome. We maintain that, when subdural collections and perisellar engorgement are detected on unenhanced MRI in the proper clinical setting, contrast enhancement may not be necessary for the diagnosis.

Cavernomas of the central nervous system: clinical and neuroimaging manifestations in 47 patients.

Forty seven cases of central nervous system cavernous angioma (21 males and 26 females) are described. The main clinical signs were epilepsy and brainstem syndromes. Digital subtraction intra-arterial angiography, when used, failed to reveal cavernoma. CT detected many of the lesions, but the most successful supplementary diagnostic procedure was MRI which produces highly characteristic images of cavernous angioma. The diagnosis of cavernous angioma was confirmed in the 18 cases in which the tumour was removed surgically.

[Magnetic resonance in the evaluation of neurologic complications of cervical spondylosis].

The evaluation of the neurological complications of cervical spondylosis frequently requires contrast myelography. Magnetic resonance (MR) scan would appear as a good alternative approach. We report the MR findings in 12 patients with symptoms and/or signs of spinal cord and radicular disease associated with cervical spondylosis, and we compare them with the conventional studies, including CT and CT assisted myelography. The MR image, weighted in T1, permitted to visualize the compressed spinal cord in the sagittal planes in 4 cases, with enhanced spinal cord signal in 2 of them. In a patient with herniated C5-C6 disk, the sagittal sections directly demonstrated the herniated material in the spinal canal, displacing and compressing the spinal cord. The sequences weighted in T2 demonstrated the degree of stenosis of the cervical canal caused by extradural compression. In these images, the diminished signal of the nucleus pulposus was correlated with degeneration of intervertebral disks. MR was more sensitive than the other studies to detect discal degeneration and herniation, stenosis of the spinal canal, compression of the subarachnoidal space and spinal cord injury.

[Cervicodorsal diastematomyelia in an adult].

A 44-year-old male had paraparesis which had began at age 20 years; a cleft spinal cord (diastematomyelia) was discovered at cervicodorsal level. The patient had nevus and hypertrichosis in the skin overlying the dysraphic spinal cord malformation. Both computer-assisted myelography and magnetic resonance scan showed the spinal cord segmentation and other associated disorders: bone spicula projecting between the 2 cordal halves, vertebral fusion defect and syringomyelic cavity. We emphasize the rarity of this abnormality in a so high spinal cord level and the onset of symptoms at adult age.
