From: Imaging of head and neck mucosa-associated lymphoid tissue lymphoma (MALToma)
Ultrasound (US) and computed tomography (CT) in a 58-year-old man with left thyroid lobe MALToma, presenting with neck swelling. a US shows the left lobe is enlarged and occupied by a lobulated, markedly hypoechoic mass (open arrows) with echogenic fibrous strands (arrows). There is sparing of the normal thyroid parenchyma anterior to the tumour. b Colour Doppler US shows internal vascularity. c Axial contrast-enhanced CT image shows a solitary mildly enhancing nodule in the left thyroid lobe (open arrow)
