Case Discussion
MRI features of infected dacryocystocele
Dacryocystoceles are due to an obstruction of both, proximal and distal ends of the nasolacrimal duct. They can cause:
nasal obstruction
become infected (as in this case, known as dacryocystitis)
spontaneously rupture so that their contents drain into the nose
