Abstract

ABSTRACT
Retinoblastoma is the commonest intraocular malignancy of the infants and children. It is unique central nervous system
tumor as it is visible to the naked eye and can be diagnosed with confidence clinically and radiologically without taking
biopsy by non-invasive modalities like CT scan and MRI. CT scan can easily pick calcification in the tumor, its extent
with involvement of nose and sinuses. It can also demonstrate bony erosion if any. MRI on the other hand can easily
demonstrate peri neural and trans scleral extension of the tumor. In this way treatment options can also be planned
along with prediction of prognosis in cases of retinoblastoma by using non invasive techniques like CT and MR scans.
Objective: Objective of this study is to determine the role of computed tomography and magnetic resonance imaging
in diagnosis and management of retinoblastoma.
Methods: This study was performed in Radiology Department of Hayatabad Medical Complex Peshawar from 1st of
January 2019 to 1st December 2019. It is was an observational descriptive study.
Results: CT scan is highly sensitive in diagnosis of retinoblastoma while MRI is highly sensitive in detecting peri neural
and trans scleral spread of tumor for management plans.
Conclusion: CT scan and MRI are non-invasive methods with CT having high sensitivity and moderate specificity for
detecting Retinoblastoma. MRI scan being helpful in diagnosing perineural and trans scleral spread. Both of these
imaging modalities can help in prompt diagnosis, management and prognosis of retinoblastoma.
