Abstract: A 62 year old woman status post radical nephroureterectomy for high grade urothelial carcinoma was found on CT to have a 1 cm retroperitoneal nodule in the nephrectomy bed. The nodule`s differential diagnosis included recurrent urothelial carcinoma versus relocation of the patient`s splenule seen on earlier CT imaging. We report using SPECT/CT with Tc-99m labeled denatured red blood cells to definitively diagnose the nodule as a relocated splenule.

Abstract: Focal fibrocartilaginous dysplasia (FFCD) of the tibia is a rare tumor like lesion probably caused by a failure of differentiation in the pes anserinus area. The children usually present with unilateral tibia vara and conspicuous walking features. The radiographic appearance of FFCD is pathognomic. In most cases this benign condition undergoes spontaneous resolution. Curettage or corrective osteotomy is only indicated when the deformity is persistent or progressive. We report the case of a 14 months old toddler diagnosed with FFCD. The characteristic radiographic and MRI features are presented. Further, we present for the first time the sonographic appearance of FFCD.

Abstract: We present a case of glioblastoma multiforme of the optic pathways in a 68 year old lady. Glioblastomas of the optic pathways are rare tumors; the predominant non enhancing component and the vast extent of involvement makes this a unique case. This case report further increases the database of knowledge available on the MRI characteristics of malignant optic glioma of adulthood.

Abstract: This article focuses on a relatively new concept in the Internet: “Social networking” and especially on one program that successfully found a unique way to provide a social network for Radiology: Radiolopolis. Radiolopolis (www.Radiolopolis.com) is an international Radiology network to promote education, research and clinical practice in Radiology. What makes this Radiology community unique and special is that the founders of Radiolopolis implemented multiple educational and clinical / practical programs which have been developed over the past years.

Abstract: Two cases of isolated superior mesenteric artery dissection diagnosed by contrast enhanced 64 slice CT are reported. In both, the dissection was seen extending along the entire length of the artery with one of them showing partially thrombosed false lumen. One case was associated with dissection of left renal artery with consequent renal infarcts. Although superior mesenteric artery dissection is a rare phenomenon, it should be considered in the differential diagnosis of abdominal angina.

Abstract: Aortic dissection is a life-threatening condition that might require immediate assessment and therapy. We present the case of a 71-year-old woman with essential hypertension complaining about low back pain; unenhanced thoracic-lumbar spine computed tomography examination (CT) revealed a hyperdense thin line across the aorta with an appearance of "double aortic lumen". Enhanced CT scan confirmed the diagnosis of type B aortic dissection. Radiologists should be familiar with this finding that could be considered a new radiological sign of aortic dissection on unenhanced CT examination.

Abstract: A coumadin ridge is an occasionally observed, but seldom described structure seen in the left atrium during cardiac magnetic resonance (CMR) imaging. In this case, the coumadin ridge was particularly prominent and could easily have been mistaken for a tumour or thrombus. Using the combined assessment from different CMR pulse sequences, we were able to correctly identify it as the coumadin ridge. We make the reader aware of the location and the CMR imaging features of this structure so that misdiagnosis may be avoided.
