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.

Chiari I malformation-MRI


There is evidence of tonsillar herniation below the level of foramen magnum with obliterated cisterna magna, which is consistent with Chiari I malformation. There is minimal cranial migration of the odontoid process and minimal increase in the altanto-axial distance. Odontoid process shows mild posterior inclination mildly impinging on the thecal sac.

Pleomorphic xanthoastrocytoma -MRI


Pleomorphic xanthoastrocytoma is a rare, usually benign, cortical based mass that often enhances intensely with contrast material. The most common location is in the temporal lobes. Seizures and headaches are common clinical features. Familiarity with this lesion is important in the differential diagnosis of enhancing cortical based mass. Ganglioglioma and pilocytic astrocytoma are radiological differential diagnosis. Diagnosis was histopathologically confirmed.

Osteoid Osteoma Dorsal Spine-CT


Osteoid osteomas of the spine are rare primary spine tumors consisting of osteoblasts that produce osteoid and woven bone. They often involve the posterior spinal elements, with the thoracolumbar spine being the most common site of involvement. Usually affects males under 30 and presents as vertebral column pain gradually becoming radicular in character; the pain, essentially nocturnal, is spectacularly but transiently relieved by salicylates and is accompanied by often frank stiffness of the spine. The diagnosis is based less on X rays and tomographs, than on isotope bone scanning, which reveals a focus of intense hyperfixation, and CAT scanning which shows a bony lacuna possibly with an opacity in the center producing a rosette shaped image.

Breast Imaging Conference-News

The 29th Annual Breast Imaging Conference 2009
The nearly 200 radiologists, technologists, administrators and allied healthcare professionals who attend the 29th Annual Breast Imaging Conference, held Sept. 14 to 17 at the Renaissance Glendale Hotel & Spa in Glendale, Ariz., will enjoy an innovative educational program complete with hands-on workshops and challenging presentations. This year’s BIC has new and exciting program additions in-store for attendees. One of these is a full day dedicated to workshops. Monday, Sept. 14 will offer workshops on Digital Mammography and MR Guided Biopsy, as well as two NEW workshops: Ultrasound Guided Biopsy and Hands-On Mammographic Positioning. The workshops will not run concurrently with the conference.

Upon completion of the conference, led by renowned faculty from some of the country’s most respected medical institutions, participants will be able to:

· Describe the identification and management of patients at high risk for breast cancer
· Understand the current state of breast MRI and ultrasound for screening
· Understand the technical aspects and utilization of digital mammography and CAD
· Understand the evolving role of technologists in mammography, ultrasound and MRI
· Describe methods for the optimal management of breast imaging centers

The Medical College of Wisconsin designates this educational activity for a maximum of 17.5 AMA PRA Category 1 Credits™. Additional Digital, MRI, and ultrasound credits may be obtained by attending the workshops. ASRT will provide Category A accreditation for technologists and administrators.
