Misrepresented multiple endocrine neoplasia 2: Do the British Thyroid Association guidelines accurately predict thyroid cancer risk in high-risk groups with multiple endocrine neoplasia 2? A case series.

Introduction: The incidence of thyroid nodules in the general population is around 40%. The British Thyroid Association U-grading has high sensitivity for identifying the common thyroid cancer subtypes (papillary and follicular). However, ultrasound features of the rarer medullary thyroid cancer differ, with lower sensitivity for ultrasound detection.

Sphenopalatine artery pseudoaneurysm masquerading as a second primary maxillary carcinoma.

Purpose: Maxillary sinus carcinomas usually present as a locally advanced disease at the time of diagnosis and it is extremely unusual to have a second primary maxillary carcinoma on the contralateral side after many years of completion of treatment of the first malignancy. We present here a case report of a sphenopalatine artery (SPA) pseudoaneurysm mimicking the second primary maxillary carcinoma.

Methods: We reviewed the literature for SPA pseudoaneurysm.

Which is the optimally defined vestibular cross-section to diagnose unilateral Meniere's disease with delayed post-gadolinium 3D fluid-attenuated inversion recovery MRI?

Objectives: Delayed post-gadolinium 3D fluid-attenuated inversion recovery (FLAIR) MRI is used to support a diagnosis of Ménière's disease (MD) with the ratio of the endolymphatic space (ES) to the sum of the endolymphatic and perilymphatic spaces (SEPS) on a cross-section through the vestibule being a key diagnostic criterion. It was hypothesised that the exact definition of the vestibular cross-section would influence the ES: SEPS ratio, its ability to diagnose MD, and its reproducibility.

Methods: Following institutional approval, 22 patients (five male, 17 female; mean age 52.
