Respiratory System
X-Ray:
predominantly linear interstitial pattern on xray ddx=acute causes are acute interstitial edema, viral pna. Chronic causes= chronic interstitial edema, lymphangitis carcinomatosis/neoplasm, asbestosis, IPF/ILD
CT Chest:
Honeycombing:(looks like beehive, base worse>apex)=end stage disease, IPF, collagen vascular disease, asbestosis, upper lung sarcoidosis, hypersensitivity pneumonitis
Nodular pattern:
Perilymphatic pattern-sarcoidosis
Random pattern- silicosis, pneumoconiosis, TB, metastasis, fungal
Centrilobular pattern- subacute pneumonitis, bronchiolitis
Bronchovascular pattern-lymphoproliferative disorders(post transoplant), lymphangitic carcinomatosis, kaposi sarcoma, sarcoidosis, OP, infectious PNA
GGO pattern: infectious, edema, pulm hemorrhage, OP(peripheral ggos, consolidations), PA proteinosis, Adenocarcinoma in-situ, DIP/NSIP,
Mosaic pattern : infection, small airway disease, pulm vascular disease(sickle cell)
Tree-in-bud pattern: viral/bacterial/fungal or atypical infection, ABPA, aspiration, cystic fibrosis, diffuse panbronchiolitis, RB-ILD
Septal thickening pattern: edema, lymphangitic carcinomatosis
Cystic pattern:(looks like cysts in all fields similar to emphysema): Langerhearns cell histiocytosis(cyst + nodules), lymphocytic interstitial pneumonitis, collagen vascular disease, PCP/PJP(ggos + cysts), emphysema
