Diversité clinique du lymphome de Malt orbitaire et intérêt du PET-scan. À propos de quatre cas

Although the lacrimal gland location is well-known, unspecific orbital infiltration and orbital myositis are less common, which highlights the value of a non invasive exploration before biopsy. The advantages of the PET scan in orbital ML has not been sufficiently studied. In our experience, it was useful in these four cases. Orbital ML can take on different aspects that are sometimes misleading. PET is very useful in diagnosis before the biopsy, in therapeutic decisions, and in follow-up after treatment even if it does not always fix in the orbit.
