Congenital dacryocystocele: case report and treatment

Abstract

The dacryocystocele represents a rare congenital anomaly in the medial region of the orbit caused by distal obstruction (Hasner valve) and proximal (valve Rosenmüller) RESUMOA dacriocistocele representa uma rara anomalia congênita da região medial da órbita, causada pela obstrução distal (ao nível da válvula de Hasner) e proximal (ao nível da válvula de Rosenmüller) da via lacrimal, com subsequente dilatação do saco lacrimal. Recebe o nome de mucocele, quando seu conteúdo representa muco, ou amniocele, quando o seu conteúdo é preenchido por fluido amniótico. Acomete somente 0.1% das crianças, com obstrução do ducto lácrimonasal, sendo comumente unilateral e mais frequente no sexo feminino e com predisposição familiar. O diagnóstico é realizado pelas características clínicas: lesão cística tensa, abaixo do tendão cantal medial, de coloração azulacinzentada, rósea ou vermelha acompanhada por epífora desde o nascimento. No entanto podemos utilizar exames de imagem para diagnosticar esta anomalia congênita tais como: tomografia computadorizada, ressonância magnética e ultrassonografia.Descritores: Obstrução dos ductos lacrimais/congênito; Obstrução dos ductos lacrimais/diagnóstico; Obstrução dos ductos lacrimais/terapia; Obstrução dos ductos lacrimais/ultrassonografia; Cisto epidérmico; Cisto dermóide; Relatos de casos

Bilateral congenital dacryocystocele complicated with acute dacryocystitis

“…It results from the blockage of two sites in the nasolacrimal systema resulting in lacrimal sac enlargement, which may appear as a mass. (1)(2)(3)(4) The diagnosis is made by clinical observation, but MRI, CT, ultrasound and nasal endoscopy are helpful to clarify and confirm the diagnosis. The absence of medial mass on examination does not exclude the diagnosis of bilateral congenital dacriocystocele.…”

“…However, when the diagnosis is uncertain, image tests such as computed tomography (CT), magnetic resonance imaging (MRI), and ultrasonography can be useful to show details of lacrimal system and the surrounding structures. (3) Patients can experience spontaneous resolution of dacryocystoceles, but potentially serious complications such as acute dacryocystitis requires intravenous antibiotics or surgery to prevent life-threatening sepsis and meningitis. (4) We herein present a rare case of bilateral congenital dacryocystocele with complications caused by dacryocystitis.…”

Endoscopic dacryocystorhinostomy as an option management of syndrome-related congenital dacryocystocele: a case report

“…MRI is good at cyst contents visualization and meningoencephalocele identification, USG gives information about the lacrimal sac and surrounding structures. 6,[8][9][10] In this case, a CT scan was chosen since the patient had lacrimal abnormalities and midfacial bone structure anomalies. The patient's result of CT scan was a hypodense lesion on the medial canthal region that connects with the nasolacrimal duct and suggestive of a dacryocystocele.…”

Prenatal diagnosis of unilateral dacryocystocele: A rare case report

“…Dacryocystocele is a rare congenital anomaly characterized by dilatation of the lacrimal sac as a result of obstruction of distal Hasner valve and proximal Rosenmuller valve in the lacrimal system. This anomaly is seen in the medial edge of the orbital cavity in the prenatal USG as an anechoic fluid-filled cystic structure 1 . It has been reported that dacryocystocele may coexist with additional anomalies and some syndromes.…”
