Dermoid cysts are rare benign congenital tumors comprising 1.1 % of the spinal tumors, with lumbosacral region and cauda equina being the common sites. Many cranial cases with spillage of cyst contents into the subarachnoid space have been reported. We report an extremely unusual case of symptomatic spinal dermoid cyst that ruptured into the syrinx cavity. The gold standard treatment is complet...

Three cases of midbrain gliomas are descrbied clinically and pathologically. In each case high pressure symptoms were followed by visual disturbance and the onset of syringomyelia symptoms before death. All the patients had hydrocephalus. In one case with concomitant syringobulbia, the syrinx appeared to due to CSF communicating with the cord cavity through the tissues of the brain stem. In the...

OBJECT The pathogenesis of syringomyelia in patients with an associated spinal lesion is incompletely understood. The authors hypothesized that in primary spinal syringomyelia, a subarachnoid block effectively shortens the length of the spinal subarachnoid space (SAS), reducing compliance and the ability of the spinal theca to dampen the subarachnoid CSF pressure waves produced by brain expansi...

OBJECT Syringomyelia causes progressive myelopathy. Most patients with syringomyelia have a Chiari I malformation of the cerebellar tonsils. Determination of the pathophysiological mechanisms underlying the progression of syringomyelia associated with the Chiari I malformation should improve strategies to halt progression of myelopathy. METHODS The authors prospectively studied 20 adult patie...

Male 29 years, treated surgically for a traumatic fracture of L2, was referred to us about a year after for the onset of worsening paraparesis, anesthesia in his left arm and trunk, urgent incontinence, hyperhydrosis. An MRI of the spinal cord showed the presence of a holocord syrinx, extending to the filum terminale. The patient underwent surgery via L2 laminectomy, with lysis of the arachnoid...

Previous reports have described concomitant presentation of papilledema and Chiari malformation type 1 (CM1). The pathophysiology of each and their relationship remain poorly understood. As such, different management approaches regarding treating the CM1 or the pseudotumor initially have been described, with varying degrees of success. We report the case of an 11 year old girl with 6 mm tonsill...

Syrinx (Gr. Συρινξ) was a Naiad fresh-water nymph who lived on the cold mountainsides of Arcadia. One day she was amourously pursued by the Greek god Pan, and fleeing from her chaser, she was barred by the river Ladon. She asked for assistance from her Sorores Liquidae (Watery Sisters), who transformed her into a hollow water reed. When the god’s frustrated breath blew over the river, it made a...

Background: In the issue of biodiversity, domestication birds as pets and trade animals requires special attention a conservation effort. Lovebirds (Agapornis fischeri) are popular worldwide, due to their varied ornamentation melodic chirping sound. Syrinx structure is suspected be main source sound production during period. This study aimed ...

The cervical syrinx cavity in a 27-year-old male with Chiari 1 malformation was inspected with a flexible small-caliber endoscope during syringo-subarachnoid shunting. A cleft was observed in the midline on the ventral wall of the cavity, from which blood vessels emerged and ran along the wall. Several strands accompanying the blood vessels passed from one wall to another. The endoscope was als...

We report a case of cervical intramedullary cystic schwannoma associated with segmental syrinx in a young adult without evidence of neurofibromatosis. The relevant literature is reviewed.
