Abstract


 

Background

MDCT play an important role in characterization and the assessment of the extent of the disease and involvement of adjacent and distant structures. It is widely available in most emergency centres. It provides multiplanar ( 2D ) and volumetric ( 3D ) reformation and also better perceives pathologic conditions and anatomic relationships helping in surgical treatment planning.

 

Aim

The aim of this study was to evaluate the role of MDCT in detection and characterization of lesions involving retro-peritoneum & its correlation with histopathological findings.

 

Patients and methods

This prospective study was performed on 60 patients aiming to determine the role of MDCT imaging in detection and characterization of retro-peritoneal masses. Each case was correlated with histopathological findings following open surgical biopsy, surgical excision, or image-guided biopsy by CT or USG.

 

Results

The calculated incidence of benign lesions were 8.3 %, of maliganant lesions were 61.7 % and for metastases were 30% in the studied cases.This was helpful in narrowing the differential diagnosis and thus in treatment planning.

 

Conclusion

MDCT play an important role in characterization ( size, shape, wall thickness, septa, calcification and fat content) and the assessment of the extent of the disease and involvement of adjacent and distant structures. It is better for assesing calcification, vascular invasion, enhancement patterns & specific pattern of spread. Its coronal and sagittal reformations fully delineate the peritoneal anatomy and extent of disease
