Non-contrast renal CT scan findings: a retrospective review

To evaluate the findings of unenhanced Non-contrast Renal Computed Tomography in patients with flank pain. One hundred-seventy eight seven patients with flank pain were referred for unenhanced renal computed tomography at Prince Ali Hospital between November 2008 to February 2009. The original films of each patient were reviewed and the presence of urinary tract calculi was recorded. other urinary abnormalities were also noted. Out of 178 study population, 73 patients [41%] were reported as normal, 59 patients [33%] having hydronephrosis. The stone was located in the upper third of the ureter in 27 patients [45.8%]. Thirteen patients on the right side and 10 on the left. 12.4% were found to have various renal abnormalities. Unenhanced Renal Computed Tomography is an accurate investigation for determining the presence or abscence of urinary tract calculi in patients complaining of flank pain. It identifies renal and uretric stones; location and size. Other causes of flank pain can also be identified

Posterior reversible encephalopathy syndrome: our experience at King Hussein medical center

To describe and determine the frequency of brain Magnetic Resonance Imaging findings for regional involvement of brain lobes in Posterior Reversible Encephalopathy Syndrome. This is a descriptive study which was conducted on a total of 13 patients who were diagnosed by Magnetic Resonance Imaging to have Posterior Reversible Encephalopathy Syndrome during the period between July 2009 to September 2011 at King Hussein Medical Center. Criteria for diagnosing Posterior Reversible Encephalopathy Syndrome include partial or complete expression of Posterior Reversible Encephalopathy Syndrome pattern, reversibility of the edema on follow up images, clinical presentation of neurotoxicity and presence of underlying systemic process. Standard Magnetic Resonance Imaging sequences used were unenhanced T1-T2-FLAIR diffusion-weighted and contrast-enhanced T1-weighted imaging. The frequency of regional involvement of brain lobes in Posterior Reversible Encephalopathy Syndrome in this series were as follows; the occipital lobe being affected with reversible vasogenic edema in all 13 patients [100%], followed by the parietal lobe in 10 patients [76.9%], frontal lobe in 8 patients [61.5%], temporal lobe in 2 patients [15.4%] cerebellar in 2 patients [15.4%] and pons in one patient [7.7%]. The involvement was almost symmetrical bilateral in 9 patients [75%] Neuroradiological findings along with clinical signs are consistent enough so that this entity should be readily recognizable which ensures early treatment, also prevention of potential complications as brain hemorrhage and infarction
