PURPOSE: We propose an magnetic resonance imaging (MRI)-based quantitative morphovolumetric approach to the posterior cranial fossa (PCF) and craniocervical junction (CCJ) changes in achondroplastic patients investigating possible associations with ventriculomegaly and medullary compression. METHODS: We analyzed MRI of 13 achondroplastic children not treated by surgery. 3D FSPGR T1-weighted images were used to analyze (1) PCF synchondroses; (2) PCF volume (PCFV), PCF brain volume (PCFBV), PCFV/PCFBV ratio, cerebellar volume, cerebrospinal fluid (CSF) spaces volume, and IV ventricle volume; (3) PCF (clivus, supraocciput, exocciput lengths, tentorial angle) and CCJ (AP and LL diameters of foramen magnum (FM)) morphometry; (4) measurements of FM and jugular foramina (JF) areas; and (5) supratentorial ventricular volume...

OBJECTIVE: The objective of this study is to compare the prevalence of hypoglossal canal lesions and identify differentiating imaging features. MATERIALS AND METHODS: A 15-year retrospective review of lesions of the hypoglossal nerve and hypoglossal canal, excluding those in patients with metastasis or prior head and neck cancer and those treated with radiation or surgery, was performed. Clinical findings and lesion imaging features were documented. The contrast-enhanced T1-weighted non-enhancing cystic component of hypoglossal schwannomas was compared with size-matched pathologically proven vestibular schwannomas...

BACKGROUND: Temporomandibular disorders (TMDs) are prevalent multifactorial pathologies in which the actual role of the cervical region position is controversial. OBJECTIVE: To analyze the relationship between the position of the upper cervical rachis and the symptoms of TMD. METHODS: Sixty women were recruited to this study. All of them completed a questionnaire and were subjected to a temporomadibular exploration to create two different groups: a TMD Group (n= 30) - women who suffered TMD symptoms according to the evaluation; and a control group (n= 30) - women who were free from TMD symptoms...

OBJECTIVE Grabb's line-the perpendicular distance from the basion-C2 line (pB-C2)-is a widely used radiographic measurement with significant clinical implications in patients with a complex Chiari malformation. Rigorous demonstration of the reproducibility of this measurement has not previously been reported. The authors report a standardized measurement technique with excellent inter- and intrarater reliability on T1-weighted sagittal MRI. METHODS The authors developed a standardized measurement technique that included specifications of midline slice selection, landmark and reference line definitions, and measurement technique on T1-weighted sagittal images...

Intracranial injury resultant from a chopstick penetrating the oral cavity is often fatal in children, and only 5 clinical cases have been reported. If the depth of penetration is indeterminable, due to the chopstick being removed or the remaining piece not being located, then injury management is challenging; here, we report such a case. A 26-month-old girl fell over with a plastic chopstick in her mouth. The chopstick was removed immediately and without breakage by her father. He noted that around 3 cm of the pointed end had pierced the palate...

OBJECTIVE: To describe the phenotypes, treatment response, and outcome of IgLON5 autoimmunity. METHODS: Archived serum and CSF specimens from 367 patients known to harbor unclassified antibodies which stained neural synapses diffusely (mimicking amphiphysin-IgG) were reevaluated by indirect immunofluorescence assay (IFA) using a composite of mouse tissues and recombinant IgLON5-transfected cell-based assay (CBA, Euroimmun). RESULTS: Available specimens (serum, 25; CSF, 9) from 26/367 patients (7%) had identical IFA appearance and robust IgLON5 CBA positivity...

STUDY DESIGN: This was a retrospective study. OBJECTIVE: To investigate the relationship among the craniocervical alignment, the oropharyngeal space, and the incidence of dysphagia after occipitothoracic fusion (OTF). SUMMARY OF BACKGROUND DATA: Craniocervical malalignment after OTF is one of a trigger of dysphagia. However, there has been no logical explanation for the etiology yet. METHODS: A total of 32 patients who underwent OTF (5 male, 27 female) were reviewed...

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...
