Educational treasures in Radiology: Annotate – creating interactive teaching files by Roland Talanow |
Published: 2009 Dec Issue: 3(12) :: Pages: 56-59
| Abstract: This article focuses on Annotate (www.annotate.org) – an online program for image editing and creation of interactive teaching files. This program is free to use, does not need any installation or plugin and can be used from any workstation with internet access. Multiple tools and preferences allow a customization of the program to the user needs.

Orbital Roof "Blow-in" Fracture: A Case Report and Review by Austin L. Jones et al. |
Published: 2009 Dec Issue: 3(12) :: Pages: 25-30
| Abstract: We report a relatively rare case of an essentially isolated orbital roof "blow-in" fracture in a pediatric patient. A 13-year-old male presented with headache and nausea following blunt facial trauma sustained during a skate boarding accident. CT head revealed soft tissue swelling and an abnormal bony density in the superior, posterior right orbital region. Follow-up CT orbits revealed a comminuted orbital roof "blow-in" fracture with involvement of the ethmoid air cells and two tiny foci of intracranial air. Expert consultation revealed normal ophthalmologic and neurologic examination; conservative management was recommended. The case report is followed by a brief overview of orbital fractures including pertinent radiographic considerations.

Esophageal Actinomycosis: A Case Report and Review of Radiographic Findings by Rodney D. Welling et al. |
Published: 2009 Dec Issue: 3(12) :: Pages: 44-48
| Abstract: Esophageal Actinomycosis is a rare disease with only two previous reports in the Radiology literature. We present a 27 year-old African American male with a past medical history of a renal transplant for renal disease secondary to lupus who presented with odynophagia. The computed tomography and barium swallow findings are presented as well as a differential diagnosis of infectious esophageal diseases.

Osteopoikilosis: a case report of a symptomatic patient by George Paraskevas et al. |
Published: 2009 Dec Issue: 3(12) :: Pages: 38-43
| Abstract: Osteopoikilosis (OP) is a very rare benign sclerosing bony dysplasia with an autosomal dominant inheritance. We describe the morphology of an osteopoikilosis male patient, associated with severe pain on wrist and hand joints, report on the relative literature and focus on clinical significance, due to mimicking capability of other more severe conditions such as bone metastases.

A case report of a giant presacral cystic schwannoma with sigmoid megacolon by Vinay Nyapathy et al. |
Published: 2009 Dec Issue: 3(12) :: Pages: 31-37
| Abstract: Schwannomas are peripheral nerve sheath tumours with a slow growth rate. Giant sacral schwannoma with anterior cortex erosion and associated intrapelvic extension are uncommon. Though they tend to be large when initially found, most Giant schwannomas are clinically asymptomatic. The tumour appears heterogenous due to long standing degeneration. Herein, we present a case of a large purely cystic presacral schwannoma in a patient with poliomyelitis, which has displaced adjacent organs including urinary bladder and sigmoid colon, with an initial presentation of constipation. The tumour was partially excised and diagnosis was confirmed by histo-pathology and immunohistochemistry.

Compensatory dilatation of the Azygos Venous system Secondary To Superior Vena Cava Occlusion by Francesco Paoletti et al. |
Published: 2009 Dec Issue: 3(12) :: Pages: 49-55
| Abstract: Superior vena cava (SVC) occlusion can be clinically recognized in the acute setting when the stenosing process does not allow the development of collateral venous channels, which guarantee the venous drainage to the right heart. On the contrary, when the obstruction develops progressively, the diagnosis of SVC obstruction may remain undiagnosed. In the present case, the presence of SVC thrombosis was purely coincidental. In fact, the obstruction was first noticed on diagnostic tests performed because of the malfunction of a totally implantable Porth a Cath placed into the superior vena cava (through right subclavian access), five years before, in a patient suffering from non-Hodgkin disease. Venography is the most appropriate diagnostic methodology which reveals the presence of a dilated azygos vein as a compensatory mechanism. Comparison with computed tomography allows to confirm the diagnosis and to identify the possible causes. Dilatation of the azygos vein, secondary to superior vena cava thrombosis, although a rare event, should be taken into consideration in those patients with CVC and who present with frequent episodes of deep venous thrombosis.

Pictorial review: Imaging features of unusual patterns and complications of hydatid disease by Muhammad Umar Amin et al. |
Published: 2009 Dec Issue: 3(12) :: Pages: 1-24
| Abstract: Hydatid disease is a worldwide zoonosis produced by the larval stage of the Echinococcus tapeworm. We demonstrate rare locations and unusual complications of this entity during past 6 years. Rare locations during our observation included lumbar spine, sacral spine, spleen, ovary, abdominal wall, diaphragm, pelvis and right kidney. Unusual complications included formation of bronchopulmonary fistula, complete collapse of left lung secondary to hilar location of Hydatid cyst and hydatiduria.
