RADIOGRAPHIC FINDINGS OF DENTIGEROUS CYSTS WITH CHOLESTEROL GRANULOMA

A high jugular bulb, an ectopic carotid artery, and an intratympanic cholesterol granuloma may, at times, mimic a middle ear glomus tumor, otoscopically. The otoscopic and radiographic findings which differentiate these lesions include microscopic otoscopy, tomography, carotid arteriography, and retrograde jugular venography. Examples of otoscopic and radiographic findings and procedures which enable the clinician to differentiate these lesions are presented.

Small Breed

This study was performed to evaluate full-mouth radiographic findings to determine the prevalence of dental abnormalities and analyze the relationship between dental abnormalities and age in small breed dogs. Sixteen predetermined categories of abnormal radiographic findings were evaluated in 233 small breed dogs. In total, 9,786 possible permanent teeth could be evaluated. Of those, 8,308 teeth were evaluated and abnormal radiographic findings were found in 2,458 teeth (29.6%). The most common teeth with abnormal radiographic findings were the mandibular first molars (74.5% on the left and 63.9% on the right) and the maxillary fourth premolars (40.5% on the left and 38.2% on the right). Bone loss of any type (15.8%) was the most commonly detected radiographic abnormal finding among the 16 categories. Dental conditions with a genetic predisposition were frequently occurred in the mandibular premolar teeth. Shih tzu frequently had unerupted teeth and dentigerous cysts. Among the teeth with abnormal radiographic findings, 4.5%, 19.8%, and 5.3% were considered incidental, additional, and important, respectively. Findings that were only detected on radiographs, which were not noted on routine oral examination, were more common in older dogs. Full-mouth radiographic evaluation should be performed to obtain important information for making accurate diagnoses.

Asymptomatic Patients

Abstract The incidence of cervical and lumbar fusion surgery has increased in the past twenty years, and during follow-up some of these patients develop changes at the adjacent segment. Recognizing that adjacent segment degeneration and disease may occur in the future does not alter the rating for a cervical or lumbar fusion at the time the patient's condition is determined to be at maximum medical improvement (MMI). The term adjacent segment degeneration refers to the presence of radiographic findings of degenerative disc disease, including disc space narrowing, instability, and so on at the motion segment above or below a cervical or lumbar fusion. Adjacent segment disease refers to the development of new clinical symptoms that correspond to these changes on imaging. The biomechanics of adjacent segment degeneration have been studied, and, although the exact mechanism is uncertain, genetics may play a role. Findings associated with adjacent segment degeneration include degeneration of the facet joints with hypertrophy and thickening of the ligamentum flavum, disc space collapse, and translation—but the clinical significance of these radiographic degenerative changes remains unclear, particularly in light of the known presence of abnormal findings in asymptomatic patients. Evaluators should not rate an individual in anticipation of the development of changes at the level above a fusion, although such a development is a recognized possibility.

Summary Aim: To prevent orthopedic sequelae in acute hematogenous pyogenic osteomyelitis (AHPO) of infants early diagnosis, recognition of recurrence and effective therapy is needed. This retrospective study of 47 infants with bacteriologically confirmed AHPO concerned with an analysis of the diagnostic value of systemic serum parameters compared to bone scintigraphy (BSC). Methods: AHPO was characterized initially and during the course of disease by clinical findings, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), total and differential white blood cell (WBC) count, BSC, and plain radiography. Results: CRP was the most effective serum parameter for follow- up of disease. The first sign of BSC to signal adequate response to antibiotic treatment was the decrease or normalization of hyperperfusion. Escape from therapy or poor prognosis, even when the serum parameters were normalized, was signaled by the recurrence of focal hyperperfusion and the persistent or increasing local uptake ratios on the 3-h-image over 6 weeks during a course of antibiotic treatment. Conclusion: Antibiotic treatment masks the clinical presentation, and the radiographic findings, causes non-characteristic laboratory findings, but do not prevent the scintigraphic visualization; BSC and serum parameters used in the right completion are the most successful and efficient modalities for follow-up of AHPO. Maintenance of antibiotic therapy should be done until BSC findings have reverted to normal.

The Relationship

AbstractIn this article, we reported a case of spinal muscular atrophy (SMA) type I noted to have tetraventricular hydrocephalus with Blake's pouch cyst at 8 months of age following intrathecal nusinersen therapy. The association of hydrocephalus with SMA is rarely reported in the literature. Development of hydrocephalus after intrathecal nusinersen therapy is also reported in some cases, but a cause–effect relationship is not yet established. The aim of this study was to describe the clinical characteristics of a patient with SMA type I and hydrocephalus, to review similar cases reported in the literature, and to explore the relationship between nusinersen therapy and development of hydrocephalus. The clinical presentation and radiographic findings of the patient are described and a comprehensive review of the literature was conducted. The adverse effect of communicating hydrocephalus related to nusinersen therapy is being reported and the authors suggest carefully monitoring for features of hydrocephalus developing during the course of nusinersen therapy.
