Sonography of monkeypox cutaneous lesions.

The present global outbreak of monkeypox has reached more than 79,000 cases by November 2022. While clinical features have been extensively studied, ultrasound findings in monkeypox skin lesions have not been described to date. In our work, we performed a complete sonographic study with Doppler and elastography of 3 patients with polymerase chain reaction-proven monkeypox. The most characteristic findings in skin lesions were hyperechoic epidermal thickening, dermo-hypodermal thickening with focal hypoechogenicity and increased intralesional vascularization. Regarding lymphadenopathies, we found vascularization of hilar distribution and an increased cortical stiffness and shoft hiliar area.
