MASS LESION
Pulmonary, pleural or mediastinal lesions on
the chest radiograph as an opacity greater
than 3 cm in diameter.
Symptoms and Signs
Bronchial obstruction - bronchopneumonia, lung abcess,
bronchiectasis
Due to metastasis - SVC syndrome, painful bony lesion ?
Paraneoplastic syndrome (Small cell ca) -
Others - neuromuscular, skeletall
Cutaneous
Hematological
Age - higher, sex - males, smokers
Clubbing
Cervical lymphadenopathy
Emaciation (weight loss)
by pleural effusion
Localized crepitation over mass
Cavity lesion

Signs
Post tussive crepitation
Post tussive suction (hight pitched sucking sound audible during phases of long inspiration fol owing
a bout of cough) - Hal mark sign of a thin wal ed superficial, compressible cavity connected
Cracked pot sound by percussion over empty communicating cavity

Differential Diagnosis
Infection - bacterial, fungal, parasitic
Pulmonary infarct
Septic emboli
Auto immune (wegner's granulomatosis, rheumatoid arthritis)
Congenital
Lung abscess
Localized area of suppurative necrosis within pulmonary parenchyma resulting in formation of one or more
lung cavities
Aspiration
Complications of necrotizing bacterial infection
Distal to bronchial obstruction
Septic embolism
It is commonly seen in the right lung (upper part of lower lobe and lower part of upper lobe)
Symptoms and signs
Cough with copious amount of foul smel ing purulent sputum
Clubbing
Loss of weight
Radiology
Irregularly shaped cavity with
Pulmonary, pleural or mediastinal lesions on
the chest radiograph as an opacity greater
than 3 cm in diameter.
