Diffusion Tensor Imaging in brain tumors: A study on gliomas and metastases.

Purpose: To explore the role of Diffusion Tensor Imaging in preoperative glioma grading, as well as in differentiation between gliomas and metastatic brain tumors. We measured diffusion tensor variables in enhancement and edema regions, which were compared between the different subject groups.

Materials And Methods: We performed DTI in 48 patients (11 Low Grade Gliomas, 27 High Grade Gliomas, 10 Single Metastatic brain tumors).

Successful management of bulky osseous metastasis of renal cell carcinoma with selective arterial embolization and radiofrequency ablation: a case report.

The case of a 64-year-old male patient who presented with a bulky osseous tumor metastasis from renal cell carcinoma is reported. The metastatic lesion extended from the acetabulum of the left iliac bone into the iliosacral joint.Treatment plan included selective arterial embolization followed by transdermal radiofrequency ablation, followed by consolidation irradiation.

Spontaneous intracranial hypotension: clinical and neuroimaging findings in six cases with literature review.

Spontaneous intracranial hypotension (SIH) is an uncommon but increasingly recognized syndrome. Orthostatic headache with typical findings on magnetic resonance imaging (MRI) are the key to diagnosis. Delayed diagnosis of this condition may subject patients to unnecessary procedures and prolong morbidity.
