Computed tomography of a 48-year-old man with a relapse of orbital MALToma illustrating the indolent nature of this disease. a Axial contrast-enhanced image at the initial presentation when the patient complained of left-sided proptosis and limited ocular movement. There is a diffuse homogeneous intraconal and extraconal left orbital MALToma (open arrow), with a small right intraconal MALToma (open arrow). The patient responded to radiotherapy. b Axial contrast-enhanced image 8 years later when the patient developed of right-sided proptosis. There is relapse in the right orbit (open arrow) and a clinically occult left orbital relapse (open arrow)
