Dacryolithiasis (in Ackerman's Surgical Pathology 7Ed.)

Dacryolithiasis and concretions in the lacrimal canaliculus ("tear stones") are of uncertain pathogenesis, but they are generally believed to be the result of low-grade inflammatory processes, including mycoses. If such concretions are crushed and examined microscopically, they will be seen to contain myriad mycelial elements (X40) (Grocott Stain x 200) embedded in a relatively acellular matrix (PAS x 400). Others, however, are laminated, mineralized stones with recognizable fungous or bacterial forms.

CT Demonstration of Dacryolithiasis Complicated by Dacryocystitis

Jason Asheim and Eric Spickler

From the Department of Radiology, Henry Ford Hospital, Detroit, MI

Summary: Cross-sectional imaging has demonstrated an increasing role in the evaluation of the orbits and the periorbital structures. The case presented in this article demonstrates the rare finding of a dacryolith by CT. To our knowledge, little has been reported on cross-sectional imaging characteristics of this entity in the recent radiologic literature. We demonstrated that CT can be a useful tool in diagnosing both dacryolithiasis and dacryocystitis. Obtaining an early diagnosis of dacryolithiasis is optimal to avoid potential complications, particularly because treatment is often curative.
