title: [Echographic diagnosis in tumors of the paranasal sinuses with invasion of the lacrimal ducts].
abstract: In 16 patients the histologically proven diagnosis of a lacrimal sac tumor was made; in 9 of them a paranasal sinus tumor had invaded the lacrimal pathways, in 7 patients existed a primary tumor of the lacrimal sac, A- and B-scan sonography allow a clear-cut differentiation of both these entities. Furthermore primary and tumor-related inflammations of the lacrimal pathways can be distinguished by echography, which thereby provides the decisive diagnostic basis for the different therapeutic procedures in each case.
