Honeycomb Lung Mnemonic – BIG HIPS
This mnemonic has been commonly used to recall the causes of honeycomb lung: BIG HIPS B – Bleomycin I – Idiopathic (see this case of UIP) G – Granulomas H – Histiocytosis X (or Langerhans cell histiocytosis or eosinophilic granuloma) I – Interstitial Pneumonia P – Pneumoconiosis S – Sarcoidosis Adapted from here.
Cardiophrenic Angle Mass Mnemonic – FAT PAD
This mnemonic has been commonly used to recall the differential diagnosis of a cardiophrenic angle mass: Fat PAD F – Fat P – Pericardial Cyst A – Adenopathy (lymph nodes), Aneurysm D – Diaphragmatic hernia See a Bochdalek Hernia here.
Solitary Lung Mass Mnemonic – CASH PLEASE
This mnemonic has been commonly used to recall the differential diagnosis for a solitary lung mass: CASH PLEASe C – Cancer A – Abscess S – Solitary Metastasis H – Hamartoma P – Pseudotumor L – Lymphoma E – Echinococcus A – Actinomyces S – Sequestration See a case discussion of solitary lung mass here.
Multiple Pleural Masses Mnemonic – MALLETS
This mnemonic has commonly bean used to recall the differential diagnosis of multiple pleural masses: M – Mesothelioma A – Adenocarcinoma L – Lymphoma L – Leukemia E – Empyema T – Thymoma S – Splenosis See pleural cases here.
The 5 T’s of Anterior Mediastinal Masses
This mnemonic has been used commonly to recall the five most common anterior mediastinal masses: 5 T’s 1. T – Thymus – Thymoma 2. T – Thyroid – Ectopic Thyroid masses 3. T – Thoracic Aorta – Dilated or anuerysm of the ascending aorta 4. T – Terrible lymphoma 5. T – Teratoma and germ […]

Unilateral Hyperlucent Hemithorax Mnemonic – CRAWLS
This mnemonic is commonly used to recall the differential diagnosis of a unilateral hyperlucent hemithorax: C – contralateral lung has increased density or opacity (such as posterior layering of a pleural effusion in the supine patient) R – rotation of the patient causing less attenuation of the x-ray beam A – air (pneumothorax) W – […]
Cavitating Lung Mass Mnemonic – CAVITY
This mnemonic has been used commonly to aid in recalling the differential diagnosis of a cavitating lung mass (CAVITY): C – cancer (primary bronchogenic carcinoma or pulmonary metastases) A – autoimmune (rheumatoid lung disease and Wegener’s granulomatosis) V – vascular (pulmonary emboli including septic emboli) I – infection (pulmonary abscess) T – trauma (pneumatocele) Y […]
Upper Lobe Predominant Pulmonary Fibrosis Mnemonic – CASSET P
This mnemonic has been used commonly to recall the differential diagnosis of upper lobe predominant pulmonary fibrosis (CASSET P): C – cystic fibrosis A – ankylosing spondylitis S – silicosis S – sarcoidosis E – eosinophilic granuloma T – tubercuolisis P – pneumocystis carinii pneumonia Read about idiopathic pulmonary fibrosis here, which is classically basal […]
