• Differential diagnosis of brainstem lesions,either isolated or in association with cerebellar and supra-tentorial lesions,can be challenging. Knowledge of the structural organization is crucial for the differential diagnosis and establishment of prognosis of pathologies with involvement of the brainstem. Familiarity with the location of the lesions in the brainstem is essential,especially in the pediatric population. Magnetic resonance imaging(MRI) is the most sensitive and specific imaging technique for diagnosing disorders of the posterior fossa and,particularly,the brainstem. High magnetic static field MRI allows detailed visualization of the morphology,signal intensity and metabolic content of the brainstem nuclei,together with visualization of the normal development and myelination. In this pictorial essay we review the brainstem pathology in pediatric patients and consider the MR imaging patterns that may help the radiologist to differentiate among vascular,toxico-metabolic,infectiveinflammatory,degenerative and neoplastic processes. Helpful MR tips can guide the differential diagnosis: These include the location and morphology of lesions,the brainstem vascularization territories,gray and white matter distribution and tissue selective vulnerability.
