Cervical Spondylodiscitis

Cervical spondylodiscitis was diagnosed in a 31-year-old man 2 months after palatopharyngeal flap surgery. Symptoms included pain in the neck and tingling and numbness in the left arm. The diagnosis was confirmed by magnetic resonance imaging, and the patient recovered on antibiotic treatment. We propose that the spondylodiscitis may have occurred as a result of a local infection in and around the surgical wound in the posterior pharyngeal wall.

The Subject

Objectives To visualize articulatory movement using a magnetic resonance imaging (MRI) movie of a subject with cleft lip and palate (CLP) and to demonstrate the usefulness of this method for studying oropharyngeal function. Material and Methods Dynamic changes in oropharyngeal structures were assessed with an MRI movie of a man with cleft lip and palate and in a normal adult male volunteer during the articulation of /pa/, /ta/, and /ka/. Results and Conclusions Different movement patterns were observed during articulation in the subject with CLP compared with the normal volunteer. Posterosuperior movement of the tongue and the anterior movement of the posterior pharyngeal wall were clearly visualized in the subject with CLP. Thus, MRI movies appear to be a promising tool for evaluating speech function in patients with CLP because of their noninvasive and nonradiation nature.

Mean Values

Objective: The purpose of this study was to quantify the growth of the various craniofacial and velopharyngeal structures and examine sex and race effects. Methods: Eight-five healthy children (53 white and 32 black) with normal velopharyngeal anatomy between 4 and 9 years of age who met the inclusion criteria and successfully completed the magnetic resonance imaging (MRI) scans were included in the study. Results: Developmental normative mean values for selected craniofacial and velopharyngeal variables by race and sex are reported. Facial skeleton variables (face height, nasion to sella, sella to basion, palate height, palate width) and velopharyngeal variables (levator muscle length, angle of origin, sagittal angle, velar length, velar thickness, velar knee to posterior pharyngeal wall, and posterior nasal spine to levator muscle) demonstrated a trend toward a decrease in angle measures and increase in linear measures as age increased (with the exception of posterior nasal spine to levator muscle). Only hard palate width and levator muscle length showed a significant sex effect. However, 2 facial skeleton and 6 velopharyngeal variables showed a significant race effect. The interactions between sex, race, and age were not statistically significant across all variables, with the exception of posterior nasal spine to posterior pharyngeal wall. Conclusion: Findings established a large age- and race-specific normative reference for craniofacial and velopharyngeal variables. Data reveal minimal sexual dimorphism among variables used in the present study; however, significant racial effects were observed.

Magnetic Resonance Imaging was used to quantify the effects of 1. sedation and 2. general anaesthesia with a laryngeal mask airway (LMA) in place on the minimum antero-posterior (A-P) diameters of the naso-, oro- and hypopharynx and on the angle of the epiglottis relative to the adjacent posterior pharyngeal wall. Median saggital T1-weighted images of the pharynx were obtained in 46 patients (16 awake, 14 sedated, 16 under general anaesthesia). In sedated patients, the A-P diameters of the pharynx were less than in awake patients, in particular at the levels of the epiglottis and soft palate. General anaesthesia and placement of a LMA was also associated with a reduced A-P diameter at the level of the soft palate, but with increased diameters at the levels of the tongue and epiglottis. Placement of a LMA caused abnormal downfolding of the epiglottis in most cases but this did not cause clinically significant airway obstruction.

Thoracic Spinal

Abstract Arachnoid cysts of the spinal canal are relatively common lesions that may be either intra- or extradural. These cysts are usually asymptomatic but may produce symptoms by compressing the spinal cord or nerve roots. We report a case in which an intradural thoracic arachnoid cyst became symptomatic after a routine decompressive lumbar laminectomy for spinal stenosis. Myelography revealed no abnormality, although magnetic resonance imaging and computed tomography after myelography demonstrated a mass within the posterior aspect of the thoracic spinal canal associated with anterior displacement and compression of the spinal cord. A change in the flow dynamics of the cerebrospinal fluid probably allowed the development of spinal cord compression due to one of the following: expansion of the cyst, decreased cerebrospinal fluid buffer between the cord and the cyst, or epidural venous engorgement. A concomitant and more cephalad lesion such as an arachnoid cyst should be considered when myelopathic complications arise after lumbar surgery. Magnetic resonance imaging and computed tomography after myelography are useful to demonstrate the additional pathological processes.

Kümmell’S Disease

Background: The incidence of osteoporotic vertebral compression fracture (OVCF) is increasing with the increase in the elderly population. Kümmell’s disease following OVCF occurrence is not a rare complication and is frequently associated with severe pain or neurologic deficit with progressive kyphotic deformity. Kümmell’s disease initially meant post-traumatic delayed vertebral collapse, but now it is also termed nonunion, osteonecrosis, or intravertebral vacuum cleft, all of which suggest the disruption of the healing process.Current Concepts: The major pathogenesis of Kümmell’s disease is a vascular compromise caused by mechanical stress or intravascular pathology. The key radiologic sign to diagnose Kümmell’s disease is the presence of intravertebral vacuum cleft, observed using simple X-ray, computed tomography, or magnetic resonance imaging. Magnetic resonance imaging is the most useful diagnostic tool showing gas or fluid signals. The risk factors for the progression of Kümmell’s disease after OVCF include middle-column injury, confined low signal intensity on T2-weighted image, posterior wall combined fracture, kyphotic angle >10°, and a height loss >15%. Its treatment can be broadly classified as conservative treatment, bone cement injection, and surgical treatment. The appropriate treatment method is selected based on the pain intensity, neurological symptoms, and the severity of the kyphotic deformity.Discussion and Conclusion: Kümmell’s disease usually develops along with osteoporosis. Therefore, the treatment should be focused on relief from symptoms associated with Kümmell’s disease and osteoporosis. It is recommended that an anabolic agent should be administered after the diagnosis of Kümmell’s disease, regardless of the treatment modality.

ABSTRACTMucormycosis is an emerging disease in diabetes and immunocompromised patients. Rhino-orbito-cerebral mucormycosis is one of the common forms of the disease. Mucormycosis leading to ischemic optic neuropathy is a rare complication. The role of magnetic resonance imaging (MRI) in the diagnosis of ischemic optic neuropathy is limited and uncommonly reported. We report an unusual case of mucormycosis in which MRI revealed bilateral optic nerve infarction, in addition to perineural extension of the fungus along the trigeminal nerve, another uncommon imaging finding.
