STUDY DESIGN Ligamentum flavum (LF) thickness was measured by using lumbar magnetic resonance imaging in patients with low back or leg pain. OBJECTIVE This study investigated whether LF thickening is due to hypertrophy or buckling related to disc degeneration and examined the correlations between the thickness of the LF and age, sex, body mass index(More)
Joubert syndrome (JBTS) is an autosomal recessive disorder characterized by intellectual disability, hypotonia, ataxia, tachypnea/apnea, and abnormal eye movements. A pathognomonic midbrain-hindbrain malformation seen on cranial magnetic resonance imaging (MRI), which consists of hypoplasia of the midline cerebellar vermis that resembles the cross-section(More)
PURPOSE We compared periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER, BLADE) MR technique with spin echo (SE) technique for evaluation of artifacts, and detection and delineation of brain lesions. MATERIALS AND METHODS Contrast-enhanced T1-weighted fluid attenuated inversion recovery (FLAIR) images with BLADE(More)
Ecchordosis physaliphora is a rare congenital, benign, hamartomatous, retroclival mass derived from notochordal tissue that is typically located intradurally in the prepontine cistern. Ecchordosis physaliphora is usually asymptomatic. In rare cases, ecchordosis physaliphora can be symptomatic due to tumor expansion and compression of the surrounding(More)
Heritable diseases associated with childhood tumors are sometimes defined as a probable etiologic factor or a coincidence. First of all, we must know the actual number of patients. Herein a case with medulloblastoma associated with glutaric aciduria type II [corrected] is reported for this purpose. A 5-year-old boy was admitted with nausea, vomiting, and(More)
STUDY DESIGN Histopathologic and immunohistochemical analysis of the herniated disc specimens obtained from 50 patients who had unilateral persistent radicular pain or unilateral radicular motor paresis. OBJECTIVE The aim of this study was to investigate the prevalence of inflammatory cells in lumbar disc herniations (LDH) and compare the prevalence of(More)
Idiopathic ventral spinal cord herniation is a rare cause of progressive myelopathy that demonstrates unique radiological features. We describe a case of thoracic spinal cord herniation through an anterior dural defect and discuss the characteristic findings on magnetic resonance imaging and computed tomographic myelography. A 36-year-old man presented to(More)
Guillain-Barré syndrome is a relatively common, acute, and rapidly progressive, inflammatory demyelinating polyneuropathy. The diagnosis is usually established on the basis of symptoms and signs, aided by cerebrospinal fluid findings and electrophysiologic criteria. Previously, radiologic examinations have been used only to rule out other spinal(More)
Congenital infiltrating lipomatosis of the face (CILF) is a rare disorder, causing unilateral facial asymmetry characterized by enlargement of the cheek or chin. Hemimegalencephaly is a unique malformation characterized by enlargement of a cerebral hemisphere. The association of CILF and hemimegalencephaly has rarely been reported. We present a case of(More)
The prevalence of abnormalities on brain magnetic resonance imaging (MRI) varies in primary Sjögren's syndrome (pSS) patients and they are generally multiple hyperintense areas in the subcortical and periventricular white matter on T2-weighted and fluid-attenuated inversion recovery sequences. Here, we report brainstem involvement in a patient with pSS that(More)
