background and importance: perineural cysts, also known as tarlov cysts, are benign cysts of the spinal cord containing a collection of cerebrospinal fluid. they most frequently originate in the sacral spine and can be asymptomatic. case presentation: we presented a 30-year-old woman who was referred to our clinic with an 8-month history of perianal paresthesia, slowly progressive lower back pa...

Hereditary folate malabsorption (HFM, congenital malabsorption; OMIM#229050) is a rare, potentially treatable autosomal recessive disorder with multisystem involvement.1 It caused by homozygous or compound heterozygous mutations in SLC46A1 resulting loss of function proton-coupled transporter (PCFT),2 required for intestinal absorption and transport across choroid plexus.1,2 This leads to the d...

Neurological involvement is not uncommon in patients who sustain electrical injury. The exact mechanism of nervous system damage following electrical trauma is not fully understood. The gamut of possible neurologic manifestations following electrical injury is diverse. This case report describes a young man with a unique pattern of neurological injury following an electrical burn. The combinati...

We report three patients in whom neurologic symptoms and cortical laminar necrosis developed after immunosuppressive treatment (cyclosporin A and FK 506) and polychemotherapy (vincristine and methotrexate). Initial neuroradiologic studies showed cortical and white matter involvement. Follow-up studies showed cortical hyper-intense lesions on T1-weighted MR images, consistent with cortical lamin...

CT and MR imaging of the brain and gallium-67 scintigraphy showed an enhancing, gallium-avid mass in the left middle cranial fossa of a 10-year-old girl. Craniotomy revealed an inflammatory mass related to the left trigeminal nerve. The lesion contained rodlike bacteria, and serologic tests were positive for cat-scratch disease. Neurologic involvement in cat-scratch disease is uncommon, and the...

We report a 33-year-old man with the acquired immunodeficiency syndrome (AIDS) and a solitary T-cell lymphoma. Systemic sites of lymphomatous involvement could not be identified. Subtotal resection of the lesion with cranial irradiation resulted in a marked neurologic improvement. Our case suggests that T-cell lymphomas should be considered in the differential diagnosis of a solitary mass of th...

We report an unusual case of prostatic carcinomatous meningitis and remind clinicians to maintain a high index of suspicion of meningeal involvement when patients with advanced prostatic cancer present with cerebral symptoms, back pain, or neurologic findings. The diagnosis may require repeated cytologic examinations of cerebrospinal fluid, and immunocytochemical stains should be considered to ...

The technique that we use for pattern shift visual evoked response (PSVER) is described. PSVER is a non-invasive, practical and reliable clinical test in detecting anterior visual pathways lesions even when asymptomatic. The ability to find unsuspected lesions in multiple sclerosis, making possible an early diagnosis, is underscored. We also discuss some pathophysiologic aspects and the finding...

Wilson's Disease (WD) is a rare, autosomal, recessive, inborn error of the copper metabolism, which is caused by a mutation in the copper-transporting gene, ATP7B. The presentation is usually neurologic or hepatic, which is seen in 40% of the patients. The diagnosis depends primarily on the clinical features, the biochemical parameters and the presence of the Kayser - Fleischer ring. Here, we a...

Children with rheumatic disorders may have a wide variety of clinical features ranging from fever or a simple arthritis to complex multisystem autoimmune diseases. Information about the prevalence of neurological manifestations in children with rheumatologic disorders is limited. This review describes the neurologic complications of childhood Rheumatic disease either solely or combined with sym...
