Spinal Dural Arteriovenous Fistulas: Clinical Results and Quality of Life Assessment with Surgical Treatment as a Crucial Therapy. The Joint Experience of Two Centers.

Objective: Dorsal intradural arteriovenous fistulas (AVFs) consist of a direct connection between a radicular feeding artery and the coronal venous plexus; this direct connection leads to arterialization of the venous plexus, venous congestion, and myelopathy. Controversy still exists regarding the best treatment modality of spinal dural AVFs. Surgical disconnection of spinal dural AVFs is a straightforward procedure with a high success rate and virtually no risk of recurrence or incomplete treatment.

Disseminated Oligodendroglial-like Leptomeningeal Tumor in the Adult: Case Report and Review of the Literature.

Background: Diffuse leptomeningeal glioneuronal tumor (DLGNT) was recently added to the World Health Organization classification of central nervous system tumors. DLGNT is a rare entity that occurs more commonly in pediatric patients, but occasional cases have been reported in adults. This tumor has been recognized as a distinct pathologic entity; however, its biologic behavior remains unclear.

Ultrasound-guided treatment of meralgia paresthetica (lateral femoral cutaneous neuropathy): technical description and results of treatment in 20 consecutive patients.

Objectives: The purposes of this study were to describe a technique for treatment of meralgia paresthetica (lateral femoral cutaneous neuropathy) using ultrasound guidance and to report the results of treatment.

Methods: Twenty consecutive patients (7 male and 13 female; age range, 23-66 years; mean, 39 years) with meralgia paresthetica confirmed by electromyography were treated with perineural injection of 1 mL of methylprednisolone acetate (40 mg/mL) and 8 mL of mepivacaine, 2%, under direct ultrasound guidance. Main outcome measures included the technical success of the procedure, visual analog scale score for the lateral femoral cutaneous nerve (pain, burning sensation, and paresthesia), and visual analog scale global quality of life score.

Giant intracranial aneurysm of the anterior communicating artery treated by direct surgical approach. Case report.

We report the singular case of an exceptionally large giant communicating artery aneurysm successfully treated with a direct surgical approach. The clinical presentation was a relatively short history of frontal headache. In the pre- and postcontrast CT scans the lesion mimicked an intracranial tumor.
