Emergency embolization of actively bleeding renal angiomyolipoma in a patient of tuberous sclerosis.

Renal angiomyolipoma is a benign hamartomatous lesion which contains varying proportions of abnormal blood vessels along with muscle and fat component. Tuberous sclerosis predisposes to angiomyolipoma, and when associated, the lesion is often large with increased risk of hemorrhage and complications. When this occurs, transarterial embolization and surgery are the treatment options.

Imaging findings in intracranial aspergillus infection in immunocompetent patients.

Aim: To study the neuroimaging features of craniocerebral aspergillosis infection in immunocompetent patients.

Materials And Methods: The clinical and imaging data of 12 patients of aspergillus fungal infection were retrospectively reviewed. Diagnosis of fungal infection was confirmed by histopathologic examination of surgically excised specimen, stereotactic biopsy material, or endoscopic sinus biopsy.

Can diffusion tensor metrics help in preoperative grading of diffusely infiltrating astrocytomas? A retrospective study of 36 cases.

Introduction: Diffusion weighted imaging and diffusion tensor imaging (DTI) give information about the amount and directionality of water diffusion occurring in a given tissue. Here we study the role of diffusion tensor metrics including fractional anisotropy (FA) and spherical anisotropy (CS) in preoperative grading of diffusely infiltrating astrocytomas.

Methods: We performed DTI in 38 patients with pathologically proven diffusely infiltrating astrocytomas, who were classified into two groups, i.

Combined transarterial and percutaneous coiling of a spontaneous vertebrovertebral fistula associated with neurofibromatosis Type 1. Case report.

The authors report a rare case of spontaneous left vertebrovertebral fistula associated with neurofibromatosis Type 1 in a young woman. The patient had undergone previous failed surgical attempts to close the fistula and presented to the authors with recurrence of the fistula and neurological deterioration. Successful obliteration of the fistula with combined transarterial and percutaneous coiling with Guglielmi detachable coils resulted in disappearance of the fistula and significant neurological improvement.

Diffusion tensor mode in imaging of intracranial epidermoid cysts: one step ahead of fractional anisotropy.

Introduction: The signal characteristics of an epidermoid on T2-weighted imaging have been attributed to the presence of increased water content within the tumor. In this study, we explore the utility of diffusion tensor imaging (DTI) and diffusion tensor metrics (DTM) in knowing the microstructural anatomy of epidermoid cysts.

Materials And Methods: DTI was performed in ten patients with epidermoid cysts.
