Diastematomyelia: hemicord and meningeal sheaths; single and double arachnoid and dural tubes.

چکیده
Metrizamide computed tomographic myelography demonstrates well: partial- and full-thickness diastematomyelia; the presence, shape, and (a)symmetry of the two hemicords; focal persistence of two anterior spinal arteries, one supplying each hemicord; the single or double subarachnoid space(s), arachnoid tubes, and dural tubes which encompass the hemicords; the dural septum formed by the medial walls of the two dural tubes; the dural cleft situated between the two walls of the dural septum; the bone spur within the dural cleft; and the presence of any tethering dorsal fibrous bands or aberrant dorsal nerve roots.

Subarachnoid hemorrhage caused by dural arteriovenous fistula of the sphenobasal sinus--case report.
A 59-year-old woman presented with a rare middle fossa dural arteriovenous fistula (AVF) unrelated to the cavernous sinus manifesting only as subarachnoid hemorrhage. Angiography revealed shunts between the meningeal branches of both the internal and external carotid arteries and the sphenobasal sinus. The AVF drained into the superficial middle cerebral vein (SMCV) which had a varix and an ana...
متن کاملCaudal lumbar spinal cysts in two French Bulldogs
BACKGROUND Spinal cysts are rare findings in veterinary medicine, but they are increasingly recognized due to the availability of advanced imaging techniques. Extradural meningeal cysts in French Bulldogs have not been reported previously and arachnoid cysts (diverticula) have not been reported at the caudal lumbar (L6-L7) region in dogs. CASE PRESENTATION Two French Bulldogs, aged 5 and 8 ye...
متن کاملCranial arachnoid protrusions and contiguous diploic veins in CSF drainage.
BACKGROUND AND PURPOSE Studies have suggested that arachnoid villi or granulations found in the walls of the cranial dural sinuses, olfactory mucosa, and cranial nerve sheaths function as outlets for intracranial CSF. However, their role as CSF outlets has not yet been verified. Here we show that arachnoid protrusions and contiguous diploic veins provide an alternative drainage route for intrac...
متن کاملHigh concentrations of procollagen propeptides in chronic subdural haematoma and effusion.
Procollagen propeptides increase in the CSF after subarachnoid haemorrhage, reflecting increased collagen synthesis in the arachnoid. We studied the induction of dural collagen synthesis after cerebral trauma by measuring the carboxyterminal propeptide of type I procollagen (PICP) and the aminoterminal propeptide of type III procollagen (PIIINP) in 17 subdural haematoma or effusion fluid sample...
متن کاملManagement of Type I Split Cord Malformation: Surgical Technique and Clinical Outcome
Background: Split cord malformations (SCM) are rare congenital anomalies in which the spinal cord is split into 2 hemicords with 2 dural tubes separated by a rigid septum (type I) or 2 hemicords separated by a fibrous septum in a single dural tube (type II). Objectives: Evaluation of surgical technique, timing, indications, clinical outcome and complications in treatment of SCM (type I). Materi...
