The 4 patients with clinical symptoms of dacryocystitis did not have appreciable findings on imaging. All 8 patients had a dacryocystocele on the same side as the primary sinonasal tumor and surgery. The imaging studies performed at the time of diagnosis of dacryocystocele were CT in 6 patients and MR imaging in 2 patients.

Introduction: The aim of this study was to clarify the effectiveness of various imaging modalities and characteristic imaging features in the screening of IgG4-related dacryoadenitis and sialadenitis (IgG4-DS), and to show the differences in the imaging features between IgG4-DS and Sjögren's syndrome (SS).

Dacryocystoceles are caused by obstruction of both the proximal and distal ends of the nasolacrimal duct. An imperforate Hasner valve causes the distal blockage, but the cause of proximal obstruction is less clearly understood but the Rosenmuller valve has been implicated.

Acute dacryocystitis is treated systemically, whereas chronic dacryocystitis may require dacryocystorhinostomy (DCR) . Se hela listan på pubs.rsna.org Cystic expansion of the lacrimal sac (dacryocystitis) may mimic orbital abscess clinically; however, the radiographic recog nition of a cystic, peripherally enhancing mass centered at the lacrimal fossa should exclude postseptal abscess and permit more conservative therapy. The aim of this study is to investigate the etiology and the clinical, microbiological, histopathological, and radiological findings of acquired dacryocystoceles.

Most rabbits present with unilateral disease but on occasion it can be bilateral. 1. Radiology. 2000 Apr;215(1):300-4. Abscess of the lacrimal sac due to chronic or subacute dacryocystitis: treatment with temporary stent placement in the nasolacrimal duct.

SUMMARY: The purpose of this study was to present the imaging features of primary and secondary malignant lacrimal sac and nasolacrimal duct tumors and their pattern of tumor spread in 18 patients. The most common tumor histology in our series was squamous cell carcinoma. In 15/18 patients, tumor involved both the lacrimal sac and duct at the time of diagnosis. In 11/16 patients on CT, the

Dacryocystitis is an infection of the lacrimal sac, secondary to obstruction of the nasolacrimal duct at the junction of lacrimal sac. The term derives from the Greek

Because of the course traversed by the lacrimal duct, which drains to the inferior meatus within the nose, it is surprising that the duct and sac are not infected more often.
