Magnetic resonance non-echo planar diffusion-weighted imaging accuracy in detecting cholesteatoma in comparison with clinical and surgical findings.

Objective: Magnetic resonance imaging utilising non-echo planar diffusion-weighted imaging is known to have high sensitivity and specificity in detecting cholesteatoma.

Method: Data was retrospectively collected from patients who had undergone non-echo planar diffusion-weighted imaging from 1 January 2010 to 31 December 2016. The ratio of average pixel grey-scale values between the middle-ear lesion, pons and temporal lobe was used to quantify the degree of restricted diffusion and assess the statistical significance to detect cholesteatoma.

Radiology of acute mastoiditis and its complications: a pictorial review and interpretation checklist.

Background: Mastoiditis is an otological emergency, and cross-sectional imaging has a role in the diagnosis of complications and surgical planning. Advances in imaging technology are becoming increasingly sophisticated and, by the same token, the ability to accurately interpret findings is essential.

Methods: This paper reviews common and rare complications of mastoiditis using case-led examples.

External auditory canal meningioma: imaging features in a series of three cases.

Background: Direct extension of an intracranial meningioma to involve the temporal bone is rare. Recognised sites of origin and routes of access to the middle ear and labyrinthine apparatus have been described. Direct spread through the temporal bone to primarily involve the external auditory canal has not been widely reported in the literature.

Outcomes of synchronous pulmonary nodules detected on computed tomography in head and neck cancer patients: 12-year retrospective review of a consecutive cohort.

Objective: To investigate the long-term outcomes of pulmonary nodules detected on chest computed tomography in a consecutive cohort of patients with newly diagnosed or recurrent head and neck squamous cell cancer staged between 2001 and 2003.

Results: The study included 222 patients, 148 patients with newly diagnosed head and neck cancer (group 1) and 74 patients with recurrent cancer (group 2). Abnormalities were identified in 101 patients (45.
