Parsonage-Turner syndrome is a rare and painful peripheral neuropathy that usually presents as brachial plexus neuritis and also has other nerve involvement. ⋯ The case illustrates the need for a careful clinical-neurologic examination beyond the larynx in patients presenting with idiopathic dysphonia. Parsonage-Turner syndrome should be considered as one of the rare causes in the differential diagnosis of isolated and otherwise unexplained dysphonia.

Lymphedema may disrupt local function and affect quality of life (QOL) in patients with head and neck cancer. The purpose of this study was to examine the associations among severity of internal and external lymphedema, symptoms, functional status, and QOL in patients with head and neck cancer. ⋯ Lymphedema severity correlates with symptom burden, functional status, and QOL in patients after head and neck cancer treatment.

Dynamic contrast-enhanced (DCE) MR perfusion imaging allows assessment of vascular density and integrity of tumors. The purpose of this study was to determine the diagnostic efficacy of time intensity curve analysis on DCE MRI for characterization of head and neck tumors. ⋯ DCE MR perfusion imaging provides pivotal information regarding microcirculation, potentially improves differentiation of malignant tumor from postradiation changes.
