Thyroid Cartilage Compression Causing Bow Hunter's Syndrome.

Objectives And Methods: We report a unique case of Bow Hunter's syndrome with a dominant aberrantly coursing right vertebral artery (VA), presenting with persistent dizziness and syncope despite previous decompressive surgery at vertebral levels C5-C6.

Results: Re-evaluation with computed tomography-scan during provocation of dizziness by neck rotation revealed compression of the right VA at level C6 from against the ipsilateral posterior border and superior cornu of the thyroid cartilage. Laryngoplasty resulted in complete resolution of symptoms.

Susac syndrome complicating a SARS-CoV-2 infection.

In 2020 the world was captivated by the COVID-19 pandemic. Current scientific evidence suggests an interaction of SARS-CoV-2 and the human immune system. Multiple cases were reported of patients with COVID-19 presenting with encephalopathy, confusion or agitation, stroke, and other neurologic symptoms.

Hypercalcemia induced pancreatitis as a rare presentation of primary hyperparathyroidism.

Acute pancreatitis (AP) is an inflammatory process of the pancreas. It is a relatively common cause of acute upper abdominal pain and is potentially associated with high morbidity and mortality. Underlying hypercalcemia as a cause of AP is very rare.

Predicting the Premorbid Shape of a Diseased Mandible.

Objectives/hypothesis: Virtual surgical planning (VSP) for reconstructions of advanced mandibular neoplasms that have distorted the contour of the mandible is challenging, as the premorbid shape of the mandible is unknown. We introduce a novel modeling technique, based on a statistical shape model (SSM), that has learned the shape of a normal mandible from a set of 84 mandibles, such that given a diseased mandible, the model can determine its premorbid shape.

Methods: Eighty-four control mandibles were used to generate an SSM.

Salivary duct carcinoma.

Purpose Of Review: The review puts new information on geno- and phenotype of salivary duct carcinoma (SDC) in the perspective of the updated 2017 WHO classification.

Recent Findings: The proportion of SDC is increasing. This may be because of a true rise in incidence, but certainly to better diagnostic tests and changed WHO definitions.
