ABSTRACT
Developmental anomalies of the pancreas have been reported; but among these, agenesis of dorsal pancreas is an extremely rare congenital pancreatic anomaly. It may be asymptomatic and incidentally detected on imaging or may be associated with diabetes mellitus or attacks of pancreatitis. We report a rare case of agenesis of dorsal pancreas that was detected incidentally on imaging and there was no other co-existing anomaly
ABSTRACT
To compare magnetic resonance angiography [MRA] with Intra-arterial digital subtraction angiography [IA-DSA] in detection and characterization of intracranial aneurysms. Comparative study. Department of Diagnostic Imaging, Lahore General Hospital, Lahore, from January to June 2007. Thirty patients presented with aneurismal subarachnoid haemorrhage [SAH] and focal neurological signs were selected by convenience sampling. Three dimensional time of flight [3D TOF] MRA using maximum intensity projection [MIP] was performed on all patients along with DSA. Results of 3D TOF MRA were compared with those of IA- DSA taking IA-DSA as Gold standard. Out of 30 patients 14 [46.7%] were males and 16 [53.3%] were females with mean age of 41 +/- 14.1 years. MRA detected 29 out of 30 aneurysmal lesions with sensitivity of 96.7%. regarding characterization of aneurysms results of MRA were comparable to those of IA-DSA. 3D TOF MRA technique showed a high sensitivity in this study. This technique can be used as a non-invasive screening test for intracranial aneurysms and as a suitable alternative primary examination to IA-DSA prior to aneurismal surgery
