Pulmonary and rib metastases (malignant melanoma)


Biopsy confirmed widespread metastatic malignant melanoma.  Further history noted previous excision of abdominal and forearm cutaneous melanomas.

This case is a classic example of an easily overlooked left basal pulmonary mass projected over the diaphragmatic and cardiac shadows.  The importance of tracing each rib cortex is highlighted to ensure subtle findings of bone destruction are not missed.
