Recurrent painful ophthalmoplegic neuropathy is a form of cranial neuralgia and rare source of pediatric headache. We present 2 children who presented with headaches accompanied by visual symptoms including eye pain, blurry vision, and diplopia. MRI in both patients demonstrated enhancement of the cisternal segment of the oculomotor nerve in the affected side, correlating with the observed symptoms.

Neurotoxicity is a rare side effect of metronidazole therapy. Shown here are findings of metronidazole toxicity in a patient, who received chronic metronidazole as prophylaxis for pseudomembranous colitis following bowel resection as an infant. Findings depicted include increased T2 signal in the dentate nuclei and brainstem. Discontinuing the medication resulted in reversal of the findings.

Reversible vasoconstriction is rare in the pediatric population. Typically manifesting as peripheral vasoconstriction with variable neurologic symptoms, Reversible cerebral vasoconstriction syndrome is often a diagnosis of exclusion and may not be diagnosed in the absence of angiographic imaging. Shown here are 2 cases of pediatric Reversible cerebral vasoconstriction syndrome with disparate MRI findings and arterial spin labeling perfusion findings.

Introduction: To conduct a morphometric analysis of intact and torn menisci using isotropic meniscus plane three-dimensional (3D) reconstructions on 3-Tesla MRI and compare 2D versus 3D MRI for meniscus tear characterization. Materials and methods: One hundred thirty three normal menisci from 92 patients (39 male, 53 female), and 38 arthroscopy-proven torn menisci from 36 patients (23 male, 13 female) were evaluated using 3D isotropic multi-planar MRI reconstructions and 2D MRI. Two observers measured the tibial plateau height and area, meniscal height, axial plane cross-sectional areas, and extrusion of intact menisci. Two observers also measured the meniscal tear length, tear area, and residual area of pathological menisci on 2D and 3D MRI. Intraclass correlation coefficients (ICC) were obtained. Institutional Review Board approval was obtained, and the informed consent was waived.
