Parotid Salivary Duct Sialocele Associated with Glandular Duct Stenosis in a Cat

Abstract

Feline parotid salivary duct sialocele is an uncommon disorder that has been previously reported in association with traumatic rupture of the duct in only two cats. Both cases were successfully treated by proximal duct ligation. We describe the successful surgical treatment of a parotid duct sialocele, secondary to spontaneous salivary duct stenosis, in an adult domestic shorthair cat. The cat was referred for assessment of a recurrent fluid-filled swelling on the left side of the face. Cytology of the aspirated fluid was consistent with serous saliva. The anatomical localisation of the lesion and the nature of the fluid were indicative of parotid gland/duct involvement. Retrograde sialography by parotid duct cannulation was unsuccessful because the left parotid duct opening was stenosed and obstructed by scar tissue. Surgical exploration revealed a parotid salivary duct sialocele, which was completely removed along with the parotid gland without complications.

Sialocele in the cat. A report of 2 cases

“…This salivary collection induces an inflammatory reaction resulting in a localized accumulation of saliva (Ritter and Stanley, 2012). Sialoceles have been rarely reported in cats and only 16 cases have been appeared in the literature (Wallace et al, 1972, Harrison and Garrett, 1975, Harvey, 1977, Feinman, 1990, Speakman et al, 1997, Hawe, 1998, Rahal et al, 2003, Kiefer and Davis, 2007, Rahal et al, 2007, Vallefuoco et al, 2011. Sialoceles have been reported 3 times more often in dogs than in cats (Spangler and Culbertson, 1991).…”

“…Sialoceles have been reported 3 times more often in dogs than in cats (Spangler and Culbertson, 1991). All the major salivary glands have been involved in the formation of a sialocele in cats (Wallace et al, 1972, Harrison and Garrett, 1975, Harvey, 1977, Feinman, 1990, Speakman et al, 1997, Hawe, 1998, Rahal et al, 2003, Kiefer and Davis, 2007, Rahal et al, 2007, Vallefuoco et al, 2011. Clinical signs depend on the location and the extent of the sialocele (Wallace et al, 1972, Harrison and Garrett, 1975, Harvey, 1977, Feinman, 1990, Speakman et al, 1997, Hawe, 1998, Rahal et al, 2003, Kiefer and Davis, 2007, Rahal et al, 2007, Vallefuoco et al, 2011.…”

Definitive treatment of sialoceles consists of surgical excision of the affected salivary glands and /or marsupialization and drainage of the sialocele (Wallace et al, 1972, Feinman, 1990, Speakman et al, 1997, Hawe, 1998, Rahal et al, 2003, Kiefer and Davis, 2007, Rahal et al, 2007, Vallefuoco et al, 2011.…”

Rânula bilateral com recidiva em glândula mandibular e sublingual em cão

“…Este termo consiste em uma retenção de saliva localizada em uma região anormal, resultante do extravasamento da glândula salivar ou de seu ducto em virtude de algum tipo de injúria (Kazemi et al, 2012). São caracterizadas clinicamente por aumento de volume progressivo e regular, uni ou bilateral, de tamanhos distintos, não aderido, circunscrito, não invasivo, de superfície lisa, indolor à palpação, hipertérmicos ou não, flutuante e flácidos (Vallefuoco et al, 2011) e revestido por epitélio pseudoestratificado (Gioso, 2007). Podem ser formadas na região cervical ventral, sublingual, faríngea, parotídea ou zigomática, de acordo com a glândula e ducto salivar afetado (Fossum, 2002;Kazemi et al, 2012).…”
