Congenital Indifference to Pain: An Illustrated Case Report and Literature Review by Ashkahn E Golshani et al. |
Published: 2014 Aug Issue: 8(8) :: Pages: 16-23
| Abstract: Congenital indifference to pain is a rare and debilitating congenital disease. Individuals with the disorder may have one or a combination of sensory or autonomic deficits, which can range from lack of mechanical nociception, diminished ability to detect heat and cool stimulation, to the devastating and fatal form which includes autonomic dysfunction. It is important for radiologists to be able to recognize the radiographic presentations of this rare disorder, as delay in diagnosis can lead to extensive and sometimes unnecessary workup. We present a case of congenital indifference to pain initially interpreted as a mass of the distal femur.

Transarterial Embolization of a Hepatic Arteriovenous Malformation in an Infant Using Onyx: A Case Report and Review of the Differential Diagnosis Imaging Findings by Christopher Bolus et al. |
Published: 2014 Aug Issue: 8(8) :: Pages: 33-42
| Abstract: Hepatic arteriovenous malformations are rare congenital lesions associated with significant morbidity and mortality, most commonly from high output cardiac failure. Efficient diagnosis and treatment demands an interdisciplinary approach, and the interventional radiologist plays a pivotal role in both. Imaging is important for diagnostic accuracy and treatment planning, and transcatheter embolization has become an established primary therapy. We report the clinical and imaging findings of a rare hepatic arteriovenous malformation in an infant presenting with high-output cardiac failure and pulmonary artery hypertension that was successfully treated by transarterial embolization using Onyx.

Erdheim-Chester disease with rare radiological features in a 14-year old girl with pre-B Acute Lymphocytic Leukemia and Diabetes mellitus by Varanasi Venkata Rama Krishna et al. |
Published: 2014 Aug Issue: 8(8) :: Pages: 7-15
| Abstract: We report a case of a 14 year-old girl with Diabetes Mellitus who was in remission with pre-B cell Acute Lymphoblastic Leukemia and subsequently diagnosed with Erdheim-Chester disease. Erdheim-Chester disease is a non-Langerhans cell histiocytosis and is very rare in children. In addition, the radiological features of the lesions are atypical and have not been reported in children. There is no known association between the three conditions and this is the first reported case in the literature. A literature review of Erdheim-Chester disease will be performed.

Angiosarcoma of the Liver: Imaging of a rare salient entity by Shalini Thapar et al. |
Published: 2014 Aug Issue: 8(8) :: Pages: 24-32
| Abstract: Hepatic angiosarcomas are rare mesenchymal tumors with few case series and reports describing their imaging findings in the last two decades. The computed tomography and magnetic resonance imaging findings are variable and may appear like hemangioma at one end of the spectrum and hepatoma at the other end. The use of hepatocyte specific contrast on magnetic resonance imaging may also be insufficient in making a reliable imaging diagnosis. These tumors can easily mimic hypervascular liver cancer, atypical hemangioma or metastases. This case report highlights the imaging features of this entity and also underlines that, this tumor should always be considered as a differential diagnosis for hypervascular tumors in cirrhotic patients. The current imaging paradigms for its diagnosis are also discussed.

Anti-NMDA Encephalitis: An Uncommon, Autoimmune Mediated Form of Encephalitis by Avetis Azizyan et al. |
Published: 2014 Aug Issue: 8(8) :: Pages: 1-6
| Abstract: We report an interesting case of a 19 year old female with findings on MRI suggestive of viral encephalitis. An extensive workup was negative for infectious causes and she was subsequently diagnosed with anti-NMDA encephalitis. Anti-NMDA encephalitis is a highly lethal but treatable form of autoimmune encephalitis that has recently been characterized. It is frequently found in young women and associated with an underlying teratoma. Although rare, this diagnosis should be considered in young females for whom a rapid onset of encephalitis cannot be explained by more common causes.
