Cheiro-oral-pedal syndrome as the presenting symptom of brainstem cavernous malformation: a case report.

The rare cheiro-oral-pedal syndrome (COPS) is characterized by sensory disturbances around the corner of the mouth, and in the hand and foot of the same side. The causative lesion is located in the thalamocortical projections, thalamus or brainstem and is usually due to ischemic or hemorrhagic stroke. We report a case of a patient with brain stem cavernous malformations presented as pure COPS with additional sensory disturbance in the thorax.

Diagnostic performance of advanced MRI in differentiating high-grade from low-grade gliomas in a setting of routine service.

Objective: To evaluate the usefulness of advanced MRI techniques in differentiating high-grade (HGG) from low-grade gliomas (LGG).

Material And Method: Sixty-four patients with suspected gliomas were prospectively evaluated by conventional and advanced MRI studies including MR spectroscopy (MRS), diffusion tensor imagining (DTI), and dynamic susceptibility contrast (DSC) MRI. The parametric measurements of metabolic profile, cerebral blood volume, flow (CBV, CBF), apparent diffusion coefficient (ADC), fractional anisotropy, and their ratios by internal normalization were analyzed to differentiate LGG from HGG.

Diagnostic performance of perfusion MRI in differentiating low-grade and high-grade gliomas: advanced MRI in glioma, A Siriraj project.

Background: To determine the usefulness of the perfusion MRI technique at Siriraj Hospital for differentiating between high- and low-grade gliomas by using pathological results as the gold standard.

Material And Method: The authors prospectively investigated 64 consecutive patients who were suspected as cerebral glioma from prior conventional imaging. Cerebral perfusion study was achieved during the first pass of a bolus of gadolinium-based contrast agent.

Value of diffusion tensor imaging in differentiating high-grade from low-grade gliomas.

Objective: To determine the usefulness of diffusion tensor imaging (DTI) in differentiating high-grade glioma (HGG) from low-grade glioma (LGG).

Material And Method: Patients with cerebral gliomas underwent conventional MRI and DTI before surgery. All proven pathologies were classified into two groups, i.

Cerebral venous thrombosis: diagnosis dilemma.

Cerebral venous thrombosis is increasing common disease in daily practice with sharing clinical nonspecific symptoms. This disorder is potentially lethal but treatable, oftenly it was overlooked in both clinical and radiologic in routine practice. Whenever, clinical suspected, prompt investigation by noninvasive imaging Magnetic resonance (MR) or advanced modilities such as cerebral venous thrombosis (CVT), MRV (MR Venography) will helpful in prompt diagnosis and treatment.

MDCT imaging findings for characterization pancreatic cystic lesion: differentiation between benign and malignant pattern.

Objective: The purpose of the present study was to determine the characteristic imaging findings for diagnosis of the benign or malignant nature of pancreatic cystic lesions by 64 slice multidetector computed tomography (MDCT) for further investigation or treatment.

Material And Method: A retrospective study was performed in 33 patients with pancreatic cystic lesion who underwent 64 slice MDCT to characterize and establish the diagnosis. The patients were enrolled between January 2004 and March 2009.
