Methodology: This was a retrospective study of 50 patients conducted at Ra -diology department of Rehman Medical Institute, Peshawar. Duration of study
was 6months i.e from April 2013 to September 2013. Patients were investigat-ed using 128-slice Multidetector Computed tomography (MDCT) scanner in
the Radiology department of Rehman Medical Institute Peshawar.0.5mm re -constructed images in lung window and 3mm images in mediastinal window
were viewed on workstation in axial, coronal and sagittal planes. The data was
processed using Microsoft excel 2007.
Results: A total of 50 patients were included. Age of the patients ranged
from 6 to 70 years with a mean age of 35 years. In our study, we found five
radiologic patterns on CT scan; (1)non-specific ground-glass attenuation
17(34%),(2) patchy distribution of ground-glass attenuation accompanied
by interlobular septal thickening 7(14%), (3)multifocal areas of airspace con-solidation 7(14%),(4)extensive bilateral ground-glass attenuation or airspace
consolidations with traction bronchiectasis 4(8%), and (5) nodules of variable
sizes randomly distributed in both lungs 15(30%).
Conclusion: The most common pattern was found to be patchy areas of
ground-glass attenuation. Pulmonary diseases that are induced by chemo-therapy represent particular challenges for radiologists due to non-specific
and atypical imaging features.
