BACKGROUND Cavernous venous malformation (CVM) is a common benign vascular lesion of the orbit. It was previously known as "orbital cavernous hemangioma". Localization within the lacrimal gland is extremely rare. CASE PRESENTATION We describe the case of a 76-year-old man with an asymptomatic CVM of the left lacrimal gland incidentally discovered on a routine MRI. A curative and diagnostic en bloc surgical resection was performed, allowing for histological diagnosis. CONCLUSIONS CVM of the lacrimal gland is extremely rare and usually asymptomatic. Proptosis is the main symptom. On MRI, the lesion appears hypointense with heterogeneous enhancement after Gadolinium injection on T1-weighted imaging and hyperintense on T2 STIR-weighted imaging. Histological examination is mandatory for the diagnosis. Surgical resection is usually performed.
