Differentiation of cancer from atrial fibrillation in patients with acute multifocal stroke.

Objective: Acute multifocal embolic infarction (AMEI) is conventionally caused by etiologies such as cardioembolism due to atrial fibrillation (Af), but can also be caused by serious underlying diseases such as cancer. We characterized cancer-related AMEI and identified useful indicators for cancer-associated strokes.

Methods: A retrospective analysis was performed on 35 patients with Af-related AMEI and 35 patients with cancer-related AMEI selected from 1235 consecutive patients with acute infarcts.

MR neurography for the evaluation of CIDP.

Introduction: To visualize peripheral nerves in patients with chronic inflammatory demyelinating polyneuropathy (CIDP), we used MR imaging. We also quantified the volumes of the brachial and lumbar plexus and their nerve roots.

Methods: Thirteen patients with CIDP and 12 healthy volunteers were enrolled.

Retrospective analysis of parkinsonian patients exhibiting normal (123)I-MIBG cardiac uptake.

Background: Although most patients with Parkinson's disease (PD) show decreased cardiac (123)I-metaiodobenzylguanidine (MIBG) uptake, some exhibit normal uptake. We evaluated the clinical characteristics of such patients.

Methods: We enrolled 154 non-demented patients showing parkinsonism with normal cardiac MIBG uptake and had been clinically followed up during 29.

Voriconazole-responsive disseminated nodular lesions on spinal MRI.

A 74-year-old woman was hospitalized due to dysuria, weakness and dysesthesia of the lower extremities. She was in an immunosuppressed state following the administration of methylprednisolone therapy for idiopathic interstitial pneumonia. Cerebrospinal fluid and blood cultures were negative, and no infectious biomarkers were found.
