Sturge-Weber syndrome: diffusion magnetic resonance imaging and proton magnetic resonance spectroscopy findings.
We report on the diffusion magnetic resonance imaging (MRI) and proton MR spectroscopy findings of a 26-year-old female patient with Sturge-Weber syndrome. Echo-planar trace diffusion MRI revealed mildly high signal intensity changes at parieto-occipital lobes on b = 1000 s/mm2 images, suggesting restricted diffusion. On corresponding apparent diffusion coefficient maps, those areas had moderately high signal intensity and high apparent diffusion coefficient values (around 0.9 x 10(-3) mm2/s) compared with the contralateral symmetrical normal side of the brain (0.776 x 10(-3) mm2/s). This finding was consistent with increased motion of water molecules (disintegration of the neural tissue) in these regions. Proton MR spectroscopy revealed decreased N-acetyl aspartate and increased choline peaks, indicating disintegration of neural tissue associated with neuronal loss as well.

Spontaneous involution of a non-optic astrocytoma in neurofibromatosis type I: serial magnetic resonance imaging evaluation.
A patient with neurofibromatosis type I (NF1) was followed-up with serial magnetic resonance imaging (MRI) studies over a period of 6 years. A contrast-enhancing lesion of the internal capsule, histologically proven to be pilocytic astrocytoma through stereotactic brain biopsy with mass effect and associated edema, was detected to reveal spontaneous involution on follow-up MRI studies. Although spontaneous regression of gliomas of the optic pathway-hypothalamus in patients with NF1 is relatively common in the literature, spontaneous involution of non-optic (i.e. areas other than optic pathways and hypothalamus) gliomas is rarely reported. Conservative management with follow-up MRI studies should be considered for non-optic glial tumors and tumor-like masses in patients with NF1, and surgical treatment should not be considered unless the lesions exhibit a rapid or unrelenting growth on serial MRI studies or produce significant clinical deterioration.

Arachnoid cyst of the craniospinal junction: a case report and review of the literature.
Arachnoid cysts are benign intra-arachnoid collections of cerebrospinal fluid and comprise around 1% of the intracranial masses. Unless complicated with hemorrhage, they are similar to cerebrospinal fluid in signal intensity in most cases. Diffusion-weighted magnetic resonance imaging (MRI) reveals that they have no water restriction and distinguishes them from epidermoid cysts, which show water restriction. Arachnoid cysts of the craniospinal junction are rare lesions, with only seven cases reported in the literature. Imaging findings of all craniospinal arachnoid cysts reveal a large posterior fossa arachnoid cyst extending through the foramen magnum to the level of the upper spine. We present MRI findings of a 27-year-old female patient with a craniospinal arachnoid cyst.

Isolated spinal neurobehçet disease. MR imaging findings.
MR imaging findings of a patient with isolated cervical spinal cord involvement of neurobehçet disease is presented. To our knowledge this will be the sixth case reported in the literature.

Jejunojejunal intussusception secondary to lipoma in an adult.
Lipoma is a rare cause of adult intussusception. We present the CT findings of an adult patient with jejunojejunal intussusception secondary to submucosal lipoma as the lead point in this case report.

MR imaging in epilepsy that is refractory to medical therapy.
The aim of this study was the assessment of detection rate on MRI and description of MRI findings in patients with medically intractable epilepsy. Seventy-three patients with medically intractable epilepsy between the ages of 0 and 68 years old were evaluated by MRI, on three planes with spin-echo T1, fast spin-echo T2, and fluid-attenuated inversion recovery sequences, and, if necessary, with contrast-enhanced SE T1 sequences. Cerebral infarct regions with atrophy and gliosis in 8 patients, cerebral tumors in 5 patients, hippocampal sclerosis in 16 patients, radial microbrain in 1 patient, cortical dysplasia in 3 patients, pachygyria in 2 patients, subcortical heterotopia in 2 patients, schizencephaly in 3 patients, cerebral hemiatrophy in 2 patients, tuberous sclerosis in 1 patient, herpes encephalitis in 2 patients, Rasmussen's encephalitis in 1 patient, vascular malformations in 5 patients, and no abnormality in 22 patients were detected. Magnetic resonance imaging has a high success rate in detecting structural brain abnormalities, of both temporal and extratemporal locations, associated with medically intractable epilepsy syndromes. So MRI plays a primary role in planning of the treatment, primarily surgical therapy, by detecting structural epileptogenic lesions.

Cervical hematomyelia secondary to oral anticoagulant therapy: case report.
We report a patient with cervical hematomyelia associated with oral anticoagulant therapy, which is a very rare case. Intraspinal hemorrhage is a rare but life-threatening complication of anticoagulant therapy. Early diagnosis by magnetic resonance imaging (MRI) prevents major morbidity and mortality from intraspinal hemorrhage.

Paraneoplastic limbic encephalitis: case report.
Paraneoplastic limbic encephalitis, which is also known as the remote neurological effect of cancer, is a rare neurological paraneoplastic disorder that usually presents with changes in mental status and behavioral abnormalities. Paraneoplastic limbic encephalitis had been diagnosed by clinical, laboratory and pathological studies in the pre-MRI era, but the diagnosis became much easier with MRI. We present MRI pictures of a case of paraneoplastic limbic encephalitis associated with small cell carcinoma of the lung.

Chiari III malformation: varieties of MRI appearances in two patients.
Chiari III malformation is an extremely rare anomaly, which is characterized by the herniation of posterior fossa contents, i.e., cerebellum, brain stem and fourth ventricle, and in some cases upper cervical spinal cord through a low occipital and/or upper cervical osseous defect. We report different presentations of Chiari III malformation in two unusual cases to show the diversity of imaging findings of this rare malformation.

Posttraumatic high-flow priapism treated by N-butyl-cyanoacrylate embolization.
A patient with high-flow priapism was treated by transcatheter embolization of a posttraumatic left cavernosal arteriovenous fistula using N-butyl-cyanoacrylate (NBCA), resulting in complete detumescence. Erectile function has been preserved during a 3-month follow-up. Only two patients with NBCA embolization for high-flow priapism have been reported previously.
