Interesting case..! This case is a learning pearl for me , hope would be helpful to you as well. 42 yrs male presented with fever with chills and dry cough since last one week. he was investigated in periphery with normal lab tests and cxray. treated as malarial fever imperially. today presented in OPD as nosresolving symptoms. on auscultation left basal fine crepts and harsh breath sounds heard. to me cxray appeared to be normal. so asked for CT thorax. it revealed left basal air space consolidation. lesion was retrocardiac, so that missed on cxray. clinical correlation helped in diagnosing the case. Medical management initiated.
