 Lung metastases. 

Multiple, well-defined, rounded nodules in left upper zone. Commonest cause in the elderly is metastasis.

 

MALIGNANT MELANOMA  

Malignant melanoma showing the classical cannonball metastasis

Lung metastasis

AP CXR shows multiple pulmonary nodules of varying sizes.

Medullary sponge kidneys

Multiple areas of calcification in both kidneys, both of which are grossly enlarged with bilateral cystic dilation

Glioblastoma

A rim enhancing lesion is visible in the LEFT parietal lobe in keeping with a glioblastoma

Surrounding the lesion is an area of vasogenic oedema, extending into the left periventricular region.

Miliary tuberculosis

CXR shows multiple, ill-defined nodules throughout both lungs

Primary brain tumour.

Lesion in the left cerebellar hemisphere with mass effect and surrounding oedema.

Subdural Haematoma,

A Left sided  acute on chronic subdural haematoma resulting in midline shift to the right and effacement of the left lateral ventricle. 

Lung Metastasis

Rounded opacity in the LEFT upper zone.

History and previous CT suggest that the opacity is likely to be a metastasis from a bladder tumour.

Large rounded pulmonary metastases are sometimes termed 'cannon ball metastases'. If the mass is solitary, primary lung cancer is the other main differential.

Cavitation lesion in RIGHT lung

CXR demonstrating RIGHT upper zone shadowing, with the appearance of a cavitating lesion, most likely an infectious consolidation - TB is being investigated, and malignancy cannot be ruled out.

\"Cannon Ball\" shadows on CXR

Extensive "Cannon ball" shadows suggesting metastatic malignancy across both lung fields

Mutliple, widespread Liver Metastases

Selected axial image from a contrasted CT examination demonstrates mulitple, widespread low attenuation lesions throughout the liver consistent with liver metastases. 

The primary malignancy is in sigmoid colon (Not visualised on this image)

Pulmonary fibrosis

Widespread pulmonary fibrosis, horizontal fissure is picked out due to fiborsis at based of RIGHT upper lobe
