Diagnosis of tibial neuropathy has been traditionally based on clinical examination and electrodiagnostic studies; however, cross-sectional imaging modalities have been used to increase the diagnostic accuracy and provide anatomic mapping of the abnormalities. In this context, magnetic resonance neurography (MRN) offers high-resolution imaging of the tibial nerve (TN), its branches and the adjacent soft tissues, and provides an objective assessment of the neuromuscular anatomy, abnormality, and the surrounding pathology. This review describes the pathologies affecting the TN and illustrates their respective 3 Tesla (T) MRN appearances with relevant case examples.

A wide spectrum of pediatric corpus callosal diseases can occur in the pediatric age group. Cross-sectional magnetic resonance imaging plays an important role in the diagnosis of these patients. We reviewed our imaging record and collected cases of corpus callosal pathology. The purpose of this review is to illustrate the imaging features of various corpus callosal lesions encountered in children.

To evaluate magnetic resonance imaging (MRI) features of ruptured spinal dermoid tumors with spread of lipid droplets in the central spinal canal and/or spinal subarachnoid space and to understand the underlying mechanism. ⋯ Spinal dermoid tumors ruptured into central spinal canal and/or spinal subarachnoid space have unique MRI features. The absorption of lipid droplets within central spinal canal is rather difficult, and their movement is extremely slow. We propose that fatty components within the central canal of spinal cord may be partially associated with spinal dermoid tumors developmentally.

Review Case Reports
Stroke following epidural injections--case report and review of literature.
To describe a growing number of cases associated with spinal cord and posterior circulation ischemia as a complication of cervical epidural steroid injection (CESI). ⋯ Infarction is a rare but potentially devastating complication of CESI. It may occur despite the use of fluoroscopic guidance.

Review Case Reports
Ectopic pituitary adenoma associated with an empty sella: a case report and review of the literature.
A case of ectopic pituitary adenoma in the sphenoid sinus associated with an empty sella is reported. The coexistence of an ectopic pituitary adenoma and an empty sella is quite rare. ⋯ In the present case, the hypointense line that coated the pituitary gland was clearly demonstrated on 3-tesla T2-weighted magnetic resonance imaging. The hypointense line is considered to be the pituitary capsule and was critical in diagnosing this rare entity.
