Abstract: Melanoma skin cancer is the 5th most common cancer in the UK and its incidence has been steadily increasing. Primary melanoma most commonly arises from the skin; however, it can also develop in other areas, including the eye and mucosae.

Melanoma metastasizes most commonly via lymphatics to regional lymph nodes. Haematogenous spread is more likely in advanced regional disease with a potential to metastasize to any organ. Metastatic disease arising from cutaneous melanoma has a wide anatomical distribution, spread pattern is relatively unpredictable compared to other regularly imaged malignancies.

Imaging is used for staging and follow up by demonstrating metastatic disease to direct management or outline prognosis. Computed tomography (CT) is currently the most widely used technique for tumor staging, surveillance and assessment of therapeutic response. Ultrasound, magnetic resonance imaging (MRI) and positron-emission tomography (PET)-CT are used more rarely.

In this pictorial review we demonstrate role of multiple radiological modalities( CT, MRI, Ultrasound and PET-CT) and spectrum of imaging findings of metastatic melanoma in the head, chest, abdomen and musculoskeletal system.

Summary: Pictorial review demonstrating the role of multiple radiological modalities and depicting a spectrum of imaging findings of metastatic melanoma.References: References:
