Pigmented Villonodular Synovitis-MRI

PVNS is sometimes difficult to diagnose, this case reveals extensive frond like synovial thickening, along with hemosiderin staining and T2 hypointense loose bodies confirmed on GRE sequences. Note the Black Synovium.

Partially thrombosed aneurysm versus thrombosed false lumen

Sometimes it is difficult to differentitate thrombosed false lumen from partially thrombosed aortic aneurysm as in this case. In this case the clue is peripherally placed intimal calcification which may suggest more likely possibility of partially thrombosed aneurysm.

Cervical Dermal Sinus-MRI

Congenital dermal sinuses are epithelium-lined tracts that extend from an opening in the skin through deeper tissues. Most dorsal congenital dermal sinuses are located in the lumbosacral area; a cervical location is unusual. This is a 13 year old girl patient.

Radiology 2.0

"Web 2.0" refers to a second generation of web development and design, that facilitates communication, secure information sharing, interoperability, and collaboration on the World Wide Web. Web 2.0 concepts have led to the development and evolution of web-based communities, hosted services, and applications such as social-networking sites, video-sharing sites, wikis, blogs, mashup and folksonomies. Radiology in the Web 2.0 probably refers to things like globalization, teleradiology, clinical decision support software, social networking sites dedicated to radiology, Radiology centric blogs and wikis etc. Also concepts like PACS, DICOM and HIPAA again somewhere refer to the impact of web 2.0 on radiology popularly known as Radiology 2.0.

Radiology related podcasts, RSS feeds from Table of contents of journals, and search engines like yottalook also form our current outlook of Radiology 2.0. To me Radiology 2.0 is about user friendly approach, interactivity and interoperatibility.

Stress Reaction of the Lumbar Pars Interarticularis-MRI

Injury to the lumbar pars interarticularis (spondylolysis) is reported to be a common cause of low back pain in young patients. High-field-strength magnetic resonance imaging using fat saturation techniques and dedicated coil technology is sensitive in detecting bone stress injuries of the lumbar pars interarticularis, and thus is an excellent method for diagnosis.

Google wave looks excting!

Google Wave is a new model for communication and collaboration on the web, coming later this year. Here's a preview of just some of the aspects of this new tool. I am looking forward to using it as soon as it launches.

Spinal metastatic disease-MRI

Primary sources for spinal metastatic disease include the following: Lung (31%), Breast (24%), GI (9%), Prostate (8%), Lymphoma (6%), Melanoma (4%), Unknown (2%), Kidney (1%), Others including multiple myeloma (13%). Time relation between primary and spinal metastases vary according to the site and nature of the primary. Spread from primary tumors is mainly by the arterial route via nutrient artery. Retrograde spread through the Batson plexus during Valsalva maneuver has been postulated. Direct invasion through the intervertebral foramina also can occur.

Multiple Sclerosis-MRI

Multiple discrete variable sized ovoid perpendicularly directed T2W and FLAIR hyperintense lesions (plaques), appearing iso-hypointense on T1W images and hyperintense on T2W images involving bilateral periventricular and subcortical white matter regions, including the calloso-septal interface. 35 year old female, case reported by Teleradiology Providers

Haglund's Syndrome

Haglund syndrome is a common cause of posterior heel pain, characterized clinically by a painful soft-tissue swelling at the level of the Achilles tendon insertion. On the lateral heel radiograph the syndrome is characterized by a prominent calcaneal bursal projection, retrocalcaneal bursitis, thickening of the Achilles tendon, and a convexity of the superficial soft tissues at the level of the Achilles tendon insertion, a “pump-bump.

Idiopathic Tumoral Calcinosis

Characteristic imaging findings of idiopathic tumoral calcinosis
Circular or oval, well-demarcated masses of calcium, usually located about joints
Direct involvement of the bones or joints is rare (bony erosion by anadjacent mass of calcification is seen on rare occasions)
radionuclide bone scan may reveal intense uptake in the calcific masses
The calcified deposits appear white on CT and dark on MR -- either study may demonstrate fluid-fluid levels within some of these masses.
