opacities involving the left lung is compatible with pneumonia. . ct chest : extensive left upper and lateral segment of left lower lobe consolidation with surrounding septal thickening and ground-glass. given the clinical features of fever and acute hypoxia, this most likely represents an extensive bacterial pneumonia. . cxr : as compared to the previous radiograph, there is mild improvement of the left-sided pneumonia. the opacities pre-existing in the left lung has mildly decreased in extent. unchanged normal appearance of the right lung. unchanged appearance of the cardiac silhouette. . brief hospital course: 88 yo m with limited past medical history, who ultimately presented to ed on afternoon of after 4 days of malaise and chills. found to have legionella pneumonia. . #. legionella pneumonia: patient was admitted with fevers and hypoxia and found to have positive legionella assay. he was treated on the floor with azithromycin and levofloxacin but continued to develop worsening oxygen requirment necessitating transfer to the micu. in the micu, he was maintained on facemask with high flow oxygen and transitioned to nasal cannula but continued to have mild respiratory distress. he did not require intubation. ct chest and cxr confirmed involvement of both the left upper and left lower lobe. he was provided with chest pt. after some clinical improvement, azithromycin was discontinued and he was continued on levofloxacin monotherapy for a total of 14 day course (at time of transfer was on day ). he was transferred to an ltac to continue his antibiotic course, to wean down oxygen, and to continue pulmonary therapy. he should follow up with his geriatric np after discharge from rehab. . #. left pleural effusion: patient had a thoracentesis with ip on . given elevated pleural fluid ldh to 461, is most consistent with a parapneumonic effusion. cxr post-thoracentesis on the floor was without concern for pneumothorax. pleural fluid gram stain was negative and culture showed no growth on . pleural fluid ph was 7.44 and no indication for chest tube placement. . #. crohn's disease: reportedly asymptomatic at this time. continue homed pentasa 1000 mg . . #. anemia: hct stable at 37.2, up from 35.5 at admission. baseline anemia likely from chronic gi losses from crohn's disease, though not microcytic. will need further outpatient work-up.

discharge condition: mental status: clear and coherent. level of consciousness: alert and interactive. activity status: ambulatory - requires assistance or aid (walker or cane). discharge instructions: dear mr. , you were admitted to and found to have a legionella pneumonia. we started you on antibiotics for this and your breathing improved but you were still requiring oxygen therapy at time of transfer to the rehab facility. it may take some time for your lungs to clear the infection and your oxygen will be weaned down at the rehab. you also had a build up of fluid around your left lung which was likely due to your pneumonia and we took a sample of this. you should continue antibiotics for your pneumonia for a total of 2 weeks (last day will be on ). after you are discharge from your rehab facility, please your np at the geriatric clinic to schedule a follow up. you should also discuss with further evaluation of your anemia. we have not made any changes to your other home medications. followup instructions: after you are discharge from your rehab facility, please call our geriatric clinic to schedule a follow up (phone: ). you should also discuss with your pcp further evaluation of your anemia. the following appointment was already scheduled for you: department: gastroenterology when: monday at 11:15 am with: , md building: lm campus: west best parking:
