Anxiety regarding CT Scan

CT scan results: Central airways are patent. Heart is normal in size. Minimal pericardian fluid versus thickening. Pleural spaces normal. Minimal bilateral apical pleural-parenchymal thickening with no evidence of discrete mass or nodule. Likely post infectious or inflammatory in nature. Subpleural nodule identified in left lower lobe.  Could represent volume average from posterior aspect of ipsilateral hemidiaphragm insertion. Possibility of subpleural parenchymal nodule cannot be excluded. Lungs are otherwise unremarkable. Evidence of splenomegaly.  Small, approx. 7.6 mm in diameter low attenuation lesion is identified in spleen too small to characterize. Small splenule in left upper quadrant. Regional osseous structures demonstrates no evidence of progressive lytic or blastic lesion.  
Could you decipher this for me?  Thank you.
