Lumbar epidural vein thrombosis mimicking disc herniation: A report of 3 cases.

Epidural vein thrombosis is a rare cause of lumbosciatica than can clinically and radiologically mimic other causes of nerve root compression such as disc herniation. We describe 3 unusual cases of spinal epidural plexus vein thrombosis illustrating the difficulty in preoperative diagnosis of this entity. Misinterpretation of imaging findings can lead to an erroneous diagnosis and inappropriate treatment.

Cortical thinning of temporal pole and orbitofrontal cortex in medication-naïve children and adolescents with ADHD.

Structural and functional brain studies on attention deficit/hyperactivity disorder (ADHD) have primarily examined anatomical abnormalities in the prefronto-striatal circuitry (especially, dorsal and lateral areas of the prefrontal cortex and dorsal striatum). There is, however, increased evidence that several temporal lobe regions could play an important role in ADHD. The present study used MRI-based measurements of cortical thickness to examine possible differences in both prefrontal and temporal lobe regions between medication-näive patients with ADHD (N = 50) and age- and sex-matched typically developing controls (N = 50).

[Voluminous plexiform neurofibromas of the neck region in neurofibromatosis 1].

AIM. To present the clinic, imaging and evolutive characteristics of a series of patients with neurofibromatosis 1 with voluminous plexiform neurofibromas in the neck (VPNFN) during childhood. PATIENTS AND METHODS.

Cortical thickness in fetal alcohol syndrome and attention deficit disorder.

Fetal alcohol syndrome represents the classic and most severe manifestation of epigenetic changes induced by exposure to alcohol during pregnancy. Often these patients develop attention deficit hyperactivity disorder. We analyzed cortical thickness in 20 children and adolescents with fetal alcohol syndrome and attention deficit hyperactivity disorder (group 1), in 20 patients without fetal alcohol syndrome (group 2), and in 20 control cases.

[Spontaneous involution of frontal tumors in a patient with neurofibromatosis type 1].

Aim: To present a patient with neurofibromatosis type 1 (NF1) who had cerebral tumors (in a non-optic pathway location) that regressed spontaneously.

Case Report: A girl with NF1 and cerebral tumors, probably astrocytomas, with similar neuroimaging characteristics, was studied by magnetic resonance (MR) and MR spectroscopy between 29 months and 6- years of age. The frontal tumors (one on each hemisphere) did not change size in the MR studies done during the first three and a half years of life, but, at six years, the right frontal lobe tumor had apparently disappeared and the left frontal lobe tumor had decreased in a 90% of its original size.
