The craniometric linear dimensions of the posterior fossa have been relatively well studied, but angular craniometry has been poorly studied and may reveal differences in the several types of craniocervical junction malformation. The objectives of this study were to evaluate craniometric angles compared with normal subjects and elucidate the main angular differences among the types of craniocervical junction malformation and the correlation between craniocervical and cervical angles. Angular craniometries were studied using primary cranial angles (basal and Boogard’s) and secondary craniocervical angles (clivus canal and cervical spine lordosis). Patients with basilar invagination had significantly wider basal angles, sharper clivus canal angles, larger Boogard’s angles, and greater cervical lordosis than the Chiari malformation and control groups. The Chiari malformation group does not show significant differences when compared with normal controls. Platybasia occurred only in basilar invagination and is suggested to be more prevalent in type II than in type I. Platybasic patients have a more acute clivus canal angle and show greater cervical lordosis than non-platybasics. The Chiari group does not show significant differences when compared with the control, but the basilar invagination groups had craniometric variables significantly different from normal controls. Hyperlordosis observed in the basilar inavagination group was associated with craniocervical kyphosis conditioned by acute clivus canal angles. 相似文献

OBJECTIVE AND IMPORTANCE: An arachnoid cyst at the craniocervical junction presenting with obstructive hydrocephalus as a result of blockage of the outflow of the fourth ventricle is described. This is a very rare anatomic site, with only five other cases described in the literature. CLINICAL PRESENTATION: A 37-year-old woman presented with a 9-month history of severe neck pain, persistent vomiting, visual disturbances, and numbness of the nose, cheek, and lips. She had severe bilateral papilledema on ophthalmoscopy. Magnetic resonance imaging revealed a midline cystic lesion extending down to C2. INTERVENTION: The patient underwent posterior fossa craniectomy and excision of the arachnoid cyst. She made a full recovery and was asymptomatic at follow-up examination. CONCLUSION: The symptomatology of these rare craniocervical arachnoid cysts and their development are discussed. 相似文献

Perimedullary arteriovenous fistulas (AVFs) at the craniocervical junction are uncommon, and are often fed by the anterior spinal artery, with only a few cases fed by the intradural vertebral artery (VA). A 55-year-old man presented with a case of perimedullary AVF fed by the VA at the craniocervical junction manifesting as subarachnoid hemorrhage. Left vertebral angiography demonstrated an AVF supplied by branches from the VA. Three-dimensional computed tomography angiography (3D-CTA) revealed that the feeding arteries originated from the VA at the intradural position. Two feeding arteries were coagulated and dissected, followed by coagulation of a small feeder. The draining veins became discolored and shrank. 3D-CTA performed 2 months after the operation revealed disappearance of the AVF. Open surgery was successfully performed for the almost perimedullary AVF at the craniocervical junction, and is considered to be preferable for the treatment of this disease. 相似文献

Summary Background. A CSF flow study in patients with Chiari malformation (ChM) who undergo craniocervical junction decompression (CCJD).
Methods. Using spatial modulation of magnetization (SPAMM), cerebrospinal fluid (CSF) flow velocities were measured at the prepontine
(PP), anterior cervical (AC), and posterior cervical (PC) subarachnoid spaces (SAS) in healthy subjects (n = 11) and patients
with Chiari malformation (ChM) before and/or after CCJD (n = 15). In the syringes, the intrasyrigeal pulsatile CSF motion
was estimated qualitatively as present or absent.
Findings. In normal subjects, the mean CSF velocities were 2.4 ± 0.2 cm/s (PP), 2.8 ± 0.3 cm/s (AC), and 2.4 ± 0.2 cm/s (PC). Velocities
were significantly lower than normal in patients with ChM prior to CCJD, reduced by 38%, 25%, and 79% in the 3 regions, respectively
(P<0.001). Post-CCJD, velocities were 20% (PP), 100% (AC), and 40% (PC) greater than preoperatively (P<0.001).
Conclusions. In ChM, the posterior cervical CSF flow velocity was low, increased minimally after CCJD and, by itself, had limited predictive
value. Post-CCJD, an increase of the sum of anterior and posterior cervical CSF flow velocities by more than 20% consistently
preceded or coincided with marked headache improvement. After CCJD, the finding that the intrasyringeal CSF pulsatile motion
had become absent was an earlier and more sensitive predictor of motor or sensory improvement than a reduction in syrinx’s size. SPAMM can
be used to assess whether CCJD has restored CSF flow, predict outcome and provide pathophysiological insights in ChM and syringomyelia. 相似文献

Summary We report on two children with tuberculosis of the craniocervical junction. Atlantoaxial instability was evident in both patients due to the destruction of the dens and the atlantoaxial ligaments. In addition, one child had tuberculosis involving the anterior arch of the atlas and the anterior rim of the foramen magnum. Despite anti-tuberculosis treatment and immobilization, atlantoaxial instability was evident on flexion/extension views. Successful fusion of C1 and C2 was performed in both patients. 相似文献

A rare case of arteriovenous malformation at the cervicomedullary junction is reported. A 72-year-old man developed symptoms of total transection of the upper cervical cord without evidence of subarachnoid hemorrhage. The arteriovenous malformation had an intramedullary nidus with an aneurysmal dilatation at the C-1 level. This lesion was diagnosed by magnetic resonance imaging and confirmed at autopsy. The neurological symptoms may have been due to compression of the spinal cord by the intramedullary lesion, followed by degeneration and necrosis. The usefulness of magnetic resonance imaging in the neuroradiological diagnosis is particularly emphasized. 相似文献
