Syringomyelia associated with Paget disease of the skull.
(67/83)
A 38-year-old man presented with a rare case of syringomyelia associated with Paget disease of the skull. Syringosubarachnoid (SS) shunting was performed. We speculate that deformation of the skull secondary to Paget disease caused narrowing of the foramen magnum with progressive impairment of the cerebrospinal fluid circulation, which led to syringomyelia and neurological symptoms. SS shunting is safe, effective, and technically simple, so may be a useful initial treatment for syringomyelia associated with Paget disease of the skull. (+info)

Subarachnoid hematoma of the craniocervical junction and upper cervical spine after traumatic cerebral contusion: case report.
(71/83)
Spinal subarachnoid hematoma (SSH) is a rare condition, more commonly occurring after lumbar puncture for diagnostic or anesthesiological procedures. It has also been observed after traumatic events, in patients under anticoagulation therapy or in case of arteriovenous malformation rupture. In a very small number of cases no causative agent can be identified and a diagnosis of spontaneous SSH is established. The lumbar and thoracic spine are the most frequently involved segments and only seven cases of cervical spine SSH have been described until now. Differential diagnosis between subdural and subarachnoid hematoma is complex because the common neuroradiological investigations, including a magnetic resonance imaging (MRI), are not enough sensitive to exactly define clot location. Actually, confirmation of the subarachnoid location of bleeding is obtained at surgery, which is necessary to resolve the fast and sometimes dramatic evolution of clinical symptoms. Nonetheless, there are occasional reports on successful conservative treatment of these lesions. We present a peculiar case of subarachnoid hematoma of the craniocervical junction, developing after the rupture of a right temporal lobe contusion within the adjacent arachnoidal spaces and the following clot migration along the right lateral aspect of the foramen magnum and the upper cervical spine, causing severe neurological impairment. After surgical removal of the hematoma, significant symptom improvement was observed. (+info)
