MRI of childhood dacryocystocele.

We report an unusual presentation of a dacryocystocele in a 3-day-old child, with clinical and novel MRI findings. The literature contains extensive CT documentation, but descriptions of the MRI appearances of dacryocystoceles are lacking. Although CT is the standard initial imaging modality, MRI can be helpful if there are questions as to the content of the lesion or a need for further anatomical characterization.

High-resolution conjunctival contrast-enhanced MRI dacryocystography.

We assessed high-resolution MRI of the lacrimal system with conjunctival contrast enhancement in patients with suspected stenosis. We studied 18 patients with epiphora affecting 22 eyes, using a surface coil, before and after conjunctival and intravenous Gd-DTPA. Stenosis or obstruction of the ducts was found in 18 of 22 cases: at canalicular level in 3 cases, at the sac in 7 cases, and in the nasolacrimal duct in 8 cases. Periductal pathology following surgery to the maxillary sinus or dacryocystorhinostomy was seen in three cases. In conjunction with the findings on syringing and/or conventional dacryocystography, the narrowing was classified as stenosis or obstruction.

[Lacrimal duct surgery in childhood. Retrospective study at the Munster University Ophthalmology Clinic].

UNLABELLED: Surgery on the lacrimal system in 296 children was performed at the Münster University Eye Hospital from 1987 to 1992. PATIENTS AND METHODS: The age of the patients, etiology of the obstruction and surgical strategy were analyzed retrospetively. A questionnaire was sent to the parents to allow evaluation of the results and subjective satisfaction. RESULTS: A total of 181 questionnaires was sent back to our hospital (results of 210 operations, including 24 preoperations). Of the 124 children were up to 3 years old. 197 obstructions were congenital, 7 traumatic, 4 results of inflammation, and 2 iatrogenic. In 184 patients we performed intubation with silicon tubing. Seven patients had canalicular surgery, and 19 patients had dacryocystorhinostomy (DCR). After intubation 87.5% of patients were practically without complaints, after canalicular surgery 85.7% and after DCR 78.9%. Five patients suffered from severe problems and had to be reoperated.

Magnetic resonance imaging of unilateral lacrimal gland lesions.

PURPOSE: To report the findings on magnetic resonance imaging (MRI) of various benign and malignant unilateral lacrimal gland lesions. METHODS: This is a retrospective noncomparative interventional case series. Thirty-one consecutive patients with a unilateral lacrimal gland lesion were analyzed. The preoperative MRI findings were correlated with the pathology results. The main outcome measures were anatomic extent, configuration, margins, angulation, internal features on T1- and T2-weighted images (with respect to extraocular muscles and cerebral gray matter), contrast enhancement of the lesion and adjacent bone change on MRI. RESULTS: Of the 31 patients, 21 had chronic dacryoadenitis, 3 had lymphoid tumors, and 7 had epithelial tumors including pleomorphic adenoma (3), adenoid cystic carcinoma (3), and pleomorphic adenocarcinoma (1). The results of the patients with chronic dacryoadenitis demonstrated involvement of the orbital lobe alone in 13 patients (62%), involvement of both orbital and palpebral lobes in 8 (38%), a molded configuration with ill-defined margins, sharp angles in 13 (62%), round angles in 8 (38%), lack of bone change, an isointense internal signal on T1-weighted images, a hypointense signal on T2-weighted images, and moderate contrast enhancement. The patients with lymphoid tumors demonstrated involvement of the orbital lobe, a molded configuration with ill-defined margins and sharp angles, lack of bone change, an isointense internal signal on T1-weighted images, an isointense signal on T2-weighted images, and moderate contrast enhancement. Those with epithelial tumors showed involvement of the orbital lobe, a well-circumscribed oval configuration, and round angles. Pleomorphic adenoma demonstrated smooth margins, bone expansion in two patients, and no bone change in one. Adenoid cystic carcinoma and pleomorphic adenocarcinoma showed irregular margins and bone destruction. All epithelial tumors demonstrated an isointense internal signal on T1-weighted images, a hyperintense signal on T2-weighted images, and moderate contrast enhancement. CONCLUSIONS: It is difficult to uniformly correlate the MRI features and histopathologic findings in lacrimal gland lesions. However, MRI seems to be useful in determining the etiology of a unilateral lacrimal gland lesion. Internal tissue features on T1- and T2-weighted images of MRI are most helpful in categorizing these lesions. Although the number of patients is small, our findings suggest that there are differences in orbital MRI findings of inflammatory lesions and lymphoid tumors as compared to benign and malignant epithelial tumors in the lacrimal gland fossa.

Actinomyces canaliculitis: diagnosis of a masquerading disease.

BACKGROUND: To review the diagnosis and management of seven cases of Actinomyces canaliculitis. METHODS: Culture of discharge was performed in six of seven patients with Actinomyces canaliculitis using a PD Plus/F blood culture bottle. All patients were treated by canaliculotomy with curettage of dacryoliths, followed by treatment with systemic penicillin and Sulphacetamide drops over a period of 3-6 months. Part of the curetted concretions was fixed on a glass slide and part was sent to the laboratory for culture. RESULTS: Four patients were women and three men with age ranging between 43 and 90 years. The average time lapse between onset of symptoms until diagnosis was 3 years. All cases presented with epiphora, chronic conjunctivitis, palpably thickened canaliculus, and yellow punctal discharge. Diagnosis was achieved by culture of discharge in three of six cases, culture of concretions in three of five cases, and staining of dacryoliths in all seven cases. Follow-up ranged between 12 and 48 months. The canaliculitis resolved completely and all patients have patent canalicula. CONCLUSIONS: Actinomyces canaliculitis presents with epiphora, chronic purulent conjunctivitis, a palpably thickened canaliculus, and yellow punctual discharge. In suspect cases canuliculotomy and curettage should be performed, although canalicular reconstruction is generally unnecessary. Culture of discharge and concretions using PD Plus/F blood culture medium gave improved results over accepted norms. Fixation of smeared concretions on a slide in alcohol is simple and is diagnostic of the disease. We recommend long-term systemic penicillin treatment in Actinomyces canaliculitis.

Bilateral canaliculitis following SmartPLUG insertion for dry eye syndrome post LASIK surgery.

BACKGROUND: Dry eyes are a common symptom following LASIK corneal refractive surgery. Treatments include topical lubricants to supplement the tear film, and punctal occlusion to reduce tear outflow. Canaliculitis is a recognised complication of punctal plugs, but has not previously been described following insertion of newer generation semi-permanent intra-canalicular plugs, such as the SmartPLUG. METHODS: Case report. RESULTS: We describe a 60-year-old female who underwent bilateral LASIK surgery leading to aggravation of her dry eye syndrome. She was managed with the insertion of semi-permanent intra-canalicular moldable silicone SmartPLUGs. She subsequently developed bilateral canaliculitis requiring bilateral canaliculotomy. CONCLUSIONS: To the best of our knowledge, this is the first report of bilateral canaliculitis following intra-canalicular SmartPLUG insertion. This case illustrates that punctal occlusion with the newer generation intra-canalicular plugs carries a risk of canaliculitis and that irrigation is not always effective in removing these devices.

Marginal zone lymphoma of the lacrimal gland spreading to the lung and the bone marrow 11 years after first symptoms.

We report on the case of a 52-year-old male presenting with an extranodal marginal zone lymphoma of the mucosa-associated tissue (MALT lymphoma) in the lung 11 years after radiotherapy for a MALT lymphoma of the lacrimal gland, which was primarily diagnosed as dacryoadenitis. Both tumors were investigated by immunohistochemistry and molecular techniques demonstrating their clonal genetic relationship. Both harbored the t(14;18)(q32;q21) and a trisomy 3 and showed identical immunoglobulin heavy-chain gene rearrangements. At the time of pulmonary relapse, clonal CD20- and CD43-positive bone marrow B lymphocytes were detected as well. The elaboration of this case emphasizes the importance of the combined use of modern diagnostic methods for establishment of correct diagnosis of MALT lymphomas at late relapses, which is essential for proper patient management.
