CXR ?TB Pneumonia – Left Upper Lobe
Consolidation Cavitation and Endobronchial Spread

CT scan in the axial plane of the left upper lobe of a 28-year-old immigrant with cough shows a focal subsegmental consolidation with focal cavitation (yellow arrowhead) subtended by a thick-walled subsegmental airway. There are extensive tree in bud changes ringed in white (b and c) indicating transbronchial spread. Lab tests confirmed a diagnosis of TB and the patient was treated with RISE, a 4-month treatment regimen of rifapentine-moxifloxacin for mycobacterium tuberculosis.

CT scan in the coronal plane of the left upper lobe of a 28-year-old immigrant with cough shows a thickening of the walls of the segmental, (blue circle) and subsegmental airway disease (teal circle ) as well as small airways disease characterised by tree in bud changes (ringed in whit)e These findings indicate transbronchial spread.

60-year-old immunocompromise female presents with a cough and weight loss CXR shows a diffuse miliary pattern. Final diagnosis was mycobacterium tuberculosis. Associated findings include healed right sided rib fractures and surgical clips in the left axilla
Ashley Davidoff MD TheCommonVein.net 265Lu 136197

60-year-old female presents with a cough and weight loss. Coronal CT shows miliary nodules throughout both lung fields. The nodules appear to be distributed along the bronchovascular bundles and the lymphatics and are noted in centrilobular, fissural and pleural locations. She responded well to treatment and final diagnosis was mycobacterium tuberculosis.

CT Miliary Tuberculosis Centrilobular Nodules Suggesting Arteriolar Small Airway and or Lymphatic Involvement Also Fissural Nodules and Pleural Nodules

60-year-old immunocompromised female presents with a cough and weight loss. Axial CT shows miliary nodules throughout both lung fields. Some of these nodules are centrilobular (c, maroon arrowheads) and others are fissural based (b, pink arrowheads). In some of the secondary lobules there are 2 centrilobular nodules indicating involvement of the airway and arteriole and or the lymphatics (c white rings). One lobule shows centrilobular and interlobular nodules (c gray ring anteriorly). She responded well to treatment and final diagnosis was mycobacterium tuberculosis.

Pleural Effusion

80 year old Russian woman who initially presented with a cavitating LUL nodule that was biopsied and thought to represent sarcoidosis
In December the nodules in the LUL enlarged with an arborising pattern involving the posterior subsegment of the LUL as well as an unchanged RUL ground glass infiltrate
Subsequent diagnosis of TB was made
Initially there was progressive disease in the LUL and lingula with new cavitation in the lingula infiltrate/nodule and extension of the infiltrate in the LUL with a new calcification. These findings were consistent with reactivation TB .
Repeated sputa were positive for acid fast bacilli
More recently new micronodularity was noted in the right lung .
Now 1 month later she presents with a large right pleural effusion and a smaller left effusion
