OBJECTIVE: Craniocervical junction arteriovenous fistulas(CCJ-AVFs)are extremely rare lesions that may result in both subarachnoid hemorrhage(SAH)and myelopathy. Diagnosis of CCJ-AVF is difficult and may be delayed due to variable clinical features and a spectrum of neuroradiological findings. To elucidate the clinical characteristics of CCJ-AVF, we analyzed the clinical symptoms, neuroimaging findings, and the results of surgical treatment in five patients. RESULTS: Among the five patients, four were diagnosed with dural AVFs, and the remaining patient was diagnosed with radicular AVF...

Postoperative pseudomeningocele is an uncommon complication of craniospinal surgery. Diagnosis is reached on a postoperative computed tomography and magnetic resonance (MR) imaging. Demonstration of the location and dimension of the dural defect before surgical therapy is a very important. T1- and T2-weighted MR images revealed a significant pseudomeningocele extending from left cervicooccipital region. Magnitude and phase-contrast-MR images showed a cerebrospinal fluid (CSF) flow into pseudomeningocele, but they no revealed dural defect...

BACKGROUND CONTEXT: The occipito-C2 angle (O-C2a) influences the oropharyngeal space. However, O-C2a has several limitations. There is no normal value of O-C2a due to wide individual variations, and O-C2a does not reflect translation of the cranium to the axis, another factor influencing the oropharyngeal space in patients with atlantoaxial subluxation. PURPOSE: To propose a novel parameter that accounts for craniocervical junction alignment (CJA) and the oropharyngeal space...

BACKGROUND: Very little is known about the incidence and prevalence of hydrocephalus in patients with mucopolysaccharidoses (MPS). The biggest challenge is to distinguish communicating hydrocephalus from ventricular dilatation secondary to brain atrophy, because both conditions share common clinical and neuroradiological features. The main purpose of this study is to assess the relationship between ventriculomegaly, brain and cerebrospinal fluid (CSF) volumes, aqueductal and cervical CSF flows, and CSF opening pressure in MPS patients, and to provide potential biomarkers for abnormal CSF circulation...

In the field of dysmorphology, achondroplasia is a well-known disorder. Sinus pericranii (SP), however, is not. The latter condition is a rare vascular malformation characterized by abnormal connections between the intracranial and the extracranial venous drainage pathways. The etiology of SP remains unclear, and yet, these defects can be present at birth, develop spontaneously later, or evolve following head trauma. Here, we report on a 2-year-old male with achondroplasia, SP, and craniocervical junction stenosis...
