Primary Retroperitoneal Mass--- A CT Overview with FNAC /Histopathological Correlation
Journal Title: Journal of Medical Science And clinical Research - Year 2016, Vol 4, Issue 1
Abstract
Describe and characterize specific CT imaging finding in varieties of Primary Retroperitoneal masses. To confirm the diagnosis of CT by FNAC / histopathological correlation. Material & Method: A hospital based cross sectional study was conducted over a period of 1 year between 1st July 2012 to June 0th 2013 on 67 patients in the deptt. of Radio-Diagnosis, Assam Medical College and Hospital, Dibrugarh. Approved was obtained from the Institutional ethics review committees. All the patients CT on of abdomen are done both initial unenhanced CT followed by contrast CT scan by giving parenterily Iodinated low osmolar non ionic contrast media. Delayed scan were also obtain wherever necessary. Based on the findings observed on the CT Scan, a probable diagnosis was given, which was confirmed by Fine Needle Aspiration Cytology (FNAC) or by Histopathological examination (HPE) of the operative specimens. Result: Primary Retroperitoneal tumours accounted for 40.3% of the masses and secondary retroperitoneal masses (arising from retroperitoneal organs) accounted for 59.7% in this studies. Most of the primary retroperitoneal neoplasm were malignant accounting 78%. 22% of the masses were benign. Among the primary retroperitoneal masses lymphoma accounted 38% followed by liposarcoma 19% and leiomyosarcoma 14.%. nodes (100%). Among the retroperitoneal soft tissue sarcomas, liposarcoma 33.4% was commonest followed by leiomyosarcoma 25% and malignant fibrous Histiocytoma (16.7%). Conclusion: CT with its fast scanning times and good spatial resolution and multiplanar reconstruction capability is a better imaging modality for characterizing retroperitoneal masses and detecting the organ of origin. Most of the CT diagnoses were correlated with FNAC/HPE diagnosis.
