Purpose: Description of a 1 cm huge dacryolith. Radiological diagnostic, histological and chemical analysis after operation.
Method: 62-year-old man with chronic recurrent dacryocystitis. Diagnostic by dacryocystography (DCG) and CT (computertomography)-scan of the orbit with contrast intravenously and in the lacrimalsystem.
Results: The DCG showed a 1 cm filling defect in the sacculus. For further preoperative diagnostic a CT-scan of the orbit with contrast intravenously and in the lacrimalsystem was performed to exclude a tumor. The examination presented a non enhancing space-occupying lesion in the sacculus with a density of about 150 HE (Houncefieldunits). By DCG and CT the diagnosis of a dacryolith was established. Interesting was the relatively low density of the dacryolith. The chemical/mineralogical examination showed mucin and protein as ingredients, no calcium was found. The histological examination presented funghi and some cocci.
Conclusions: As a result of a chronic dacryocystitis, or only by accumulated detritus a d
