Posterior reversible encephalopathy syndrome following pembrolizumab therapy for relapsed Hodgkin's lymphoma.

Posterior reversible encephalopathy syndrome (PRES) is characterized by a group of central nervous system related symptoms. Diagnosis is usually made by computed tomography or magnetic resonance imaging. Common causes can be arterial hypertension, sepsis, autoimmune disorders, and medications.

Möbius syndrome.

We describe a case of Möbius syndrome in a 3-month-old infant. Striking imaging findings of pontine hypoplasia in the region of the 6th and the 7th nerve complexes were noted. In addition, absence of the middle cerebellar peduncles was noted, a finding that, to our knowledge, has never been reported before in the literature.

Incremental benefit of maximum-intensity-projection images on observer detection of small pulmonary nodules revealed by multidetector CT.

Objective: Our purpose was to assess the incremental effect of maximum-intensity-projection (MIP) image processing on the ability of various observers to detect small (<1 cm in diameter) central and peripheral lung nodules revealed by multidetector CT.

Materials And Methods: We retrospectively identified 25 patients with metastatic disease, each having from two to nine nodules that were 3-9 mm in diameter. Two senior and three junior reviewers interpreted all images on a workstation.
