Diffusion weighted MR Imaging of breast for differentiation of benign from malignant lesions and histopathological correlation

The article highlights utility of Diffusion Weighted MR Imaging of breast in differentiating benign and malignant lesions along with correlation with histopathological findings. DWI of breast lesions can help predict nature of lesion with reasonable confidence limit.

Orbital apex osteodural fistula - An unusual surgical access.

Dural arteriovenous fistulas (DAVFs) are fistulas connecting the branches of dural arteries to dural veins or a venous sinus. Osteodural fistulas are a rare subset of this group of diseases. We wish to report a rare case of an osteodural arteriovenous fistula at the foot of the superior ophthalmic vein (SOV), treatment of which required an unusual surgical approach via the orbit and SOV. Though access for endovascular treatment via the SOV for treatment of caroticocavernous fistulas is reported, the external approach is relatively infrequently performed, outside Europe and the Americas, with this being the first reported procedure from the Indian subcontinent. We wish to explain the steps of this unusual surgical access and highlight the salient precautions and pitfalls in the technique.
