Elderly onset atypical Lemierre's syndrome concurrent with a rheumatoid vasculitis sacral ulcer infection: a case report.

Background: Typical Lemierre's syndrome is usually secondary to an oropharyngeal infection. Recently, several cases following a primary infection site other than the oropharynx have been reported as atypical Lemierre's syndrome; although, these primary lesions are limited to the head and neck. This is the first case potentially sequential to infectious foci outside the head and neck.

Width of the normal facial canal measured by high-resolution cone-beam computed tomography.

Conclusions: In the facial canal, discrepancies between left and right side measurements at each point may be useful in the assessment and diagnosis of facial canal-related pathologies.

Objectives: This study was performed to obtain accurate and high-resolution images of the normal facial canal and measure its widths on cross-sections of the canal at anatomically and clinically important sites using high-resolution cone-beam computed tomography (CBCT).

Methods: CBCT volume data of bilateral temporal bones were obtained from 28 healthy adult volunteers.
