RATIONALE: Idiopathic hypertrophic pachymeningitis (IHP) is a rare condition, characterized by a chronic fibrosing inflammatory process usually involving either the intracranial or spinal dura mater, but rarely both. Here, we report a rare case of IHP affecting both the intracranial and spinal dura mater. We also discussed the diagnosis, management, and outcome of IHP. PATIENT CONCERNS: We reviewed the case of a 60-year-old woman presenting with chronic headache, multiple cranial nerve palsies and gait disturbance...

A dural arteriovenous fistula (DAVF) with spinal perimedullary venous drainage can cause progressive myelopathy, and it is sometimes incorrectly diagnosed as another spinal cord disease. Here we report the cases of three individuals with a DAVF (one craniocervical junction DAVF and two tentorial DAVFs) with progressive myelopathy showing unique magnetic resonance (MR) imaging findings. MR T2*WI or susceptibility-weighted imaging (SWI) demonstrated symmetrical dark signal intensity lesions predominantly in the dorsal aspect of medulla and the central gray matter of cervical spinal cord that showed the "black butterfly" silhouette...

Atlanto-axial (C1- C2) joint is accountable for up to two third of total axial craniocervical rotation. Its major role in pivotal rotation of cervical spine makes it more vulnerable to a certain type of injury known as atlanto-axial rotatory subluxation (AARS). Management of AARS is based on the Fielding classification which includes closed reduction and immobilization and cervical fusion in unstable cases. There are several cervical traction devices including the Gardner-Wells tongs and halter traction device...

The authors present the case of a patient that demonstrates resolution of delayed onset hypoglossal nerve palsy (HNP) subsequent to occipital condyle fracture following a motor vehicle accident. Decompression of the hypoglossal nerve and craniocervical fixation led to satisfactory long-term (>5 years) outcome. There is a scarcity of literature in recognizing HNPs following trauma and a lack of pathophysiological understanding to both a delayed presentation and to resolution versus persistence. This is the first report demonstrating long-term resolution of hypoglossal nerve injury following trauma to the craniocervical junction...

STUDY DESIGN: This was an interventional human cadaver study and radiological study. OBJECTIVES: Atlas instrumentation is frequently involved in fusion procedures involving the craniocervical junction area. Identification of the entry point at the center of atlas lateral mass (ALM) is challenging because of its rounded posterior surface and the surrounding venous plexus. This report examines using the medial edge of atlas posterior arch (MEC1) as a fixed and reliable anatomic reference to guide the entry point of ALM screws...

INTRODUCTION: The Chiari I malformation (CIM) is commonly encountered by neurosurgeons and can have different etiologies and clinical presentations. CASE REPORT: We report a CIM patient who presented with symptoms of ventral brain stem compression and was found to have a large peri-odontoid pannus. Posterior fossa decompression was performed with a planned second-stage odontoidectomy. However, at the 6-month follow-up, postoperative images demonstrated a mostly resolved pannus and improvement of the brain stem compression symptoms, and the patient progressed uneventfully without the need for odontoidectomy...

K A Gad, D M Yousem
BACKGROUND AND PURPOSE: The association of syringohydromyelia with Chiari I malformation has a wide range, between 23% and 80% of cases in the current literature. In our experience, this range might be overestimated compared with our observations in clinical practice. Because there is an impact of Chiari I malformation-associated syringohydromyelia on morbidity and surgical intervention, its diagnosis is critical in this patient population. Identifying related variables on the basis of imaging would also help identify those patients at risk of syrinx formation during their course of disease...

STUDY DESIGN: This is a retrospective review of a prospective multicenter database. OBJECTIVE: This study introduces 2 new cervical alignment measures accounting for both cervical deformity (CD) and upper cervical compensation. SUMMARY OF BACKGROUND DATA: Current descriptions of CD like the C2-C7 sagittal vertical axis (cSVA) do not account for compensatory mechanisms such as C0-C2 lordosis and pelvic tilt, which makes surgical planning difficult...

Robert Spencer, Paul Leach
BACKGROUND: Chiari type I malformation (CM-I) is characterised by caudal displacement of the cerebellar tonsils through the foramen magnum, crowding the craniocervical junction. It is being increasingly diagnosed in asymptomatic patients due to the widespread availability of MRI, and there are case reports of these patients suffering sudden death or neurological injury following head or neck trauma, raising the issue of whether they should be prohibited from contact sport participation, given the likelihood of frequent trauma...

INTRODUCTION: The precise incidence of hydrocephalus in patients with mucopolysaccharidoses (MPS) is hard to determine, because the condition lacks a formal, consensus-based definition. The diagnosis of hydrocephalus depends on symptom profile, presence of neuroimaging features, and the outcome of diagnostic tests. Although numerous techniques are used to identify MPS patients who are most likely to have hydrocephalus and respond to treatment, no definitive method exists to prove diagnosis...

Type 1 Chiari malformations (CMs) are a group of congenital or acquired disorders which include the abnormal presence of the cerebellar tonsils in the upper spinal canal, rather than the posterior fossa. The resulting anatomic abnormality causes crowding of the structures at the craniocervical junction and can impair the normal flow of cerebral spinal fluid (CSF) in this region. This impairment in CSF flow dynamics can led to the development of syringomyelia or hydrocephalus. Type 1 CMs have been associated with a wide array of symptoms resulting from either cerebellar and brainstem compression and distortion or disturbances in CSF dynamics, and can affect both children and adults...

Craniocervical junction abnormalities with atlantoaxial subluxation caused by ventral subluxation of C2 were diagnosed in a 6-month-old female Pomeranian with tetraplegia as a clinical sign. Lateral survey radiography of the neck with flexion revealed atlantoaxial subluxation with ventral subluxation of C2. Computed tomography revealed absence of dens and atlanto-occipital overlapping. Magnetic resonance imaging showed compression of the spinal cord and indentation of caudal cerebellum. The diagnosis was Chiari-like malformation, atlantoaxial subluxation with ventral displacement of C2, atlanto-occipital overlapping, and syringomyelia...
