Intraluminal tracheal lipoma as a rare cause of dyspnoea in a dog

Abstract

BackgroundTracheal tumors are rarely diagnosed in veterinary medicine and the majority of tracheal neoplasia reported in adult dogs are malignant. Intratracheal lipoma has not been previously reported in the veterinary literature.Case presentationA 7-year-old Briard dog was evaluated for inspiratory dyspnoea and an inspiratory wheeze. Cervical radiographs and tracheoscopic examination revealed an intratracheal mass that was surgically removed. The dog has been asymptomatic after the surgery.ConclusionsBased on histopathology, the mass was diagnosed as lipoma. To the authors‘ knowledge, this is the first published report of an intratracheal lipoma in the veterinary literature.

Radiographic and computed tomographic characteristics of intraluminal tracheal adenoma in a cat

“…In one study, the abnormalities of the trachea and main bronchus were missed on chest radiography, resulting in a sensitivity of 66% 3 in humans. However, despite the low sensitivity of radiography in humans, most tracheal tumors, except annular masses, appear as distinct intratracheal masses, and narrowing of the trachea is observed in almost all cases of tracheal masses diagnosed in veterinary medicine 2,4–9 . In this study, the intraluminal tracheal adenoma appeared as a dome‐shaped soft tissue opacity in the carina on radiography.…”

Tracheal Hemangioma Causing Lung Emphysema and Pneumopericardium in a Rabbit—A Case Report

“…The presence of a tumor within the lumen of the trachea may induce nonspecific clinical symptoms, such as cough and/or dyspnea. The exacerbation of symptoms occurs when a stress factor is activated, such as after exercise or eating [ 9 ]. In the presence of hemangioma, hemoptysis may be present (not in the present case), and in advanced cases, severe dyspnea may occur, and the cause of death is usually respiratory failure [ 4 ].…”

Tracheal resection and anastomosis in a dog with an osteochondroma

“…3 Although tracheal osteochondromas are seen very infrequently, they are most commonly reported in patients under the age of 2 years. 4 A previous report described 10 patients with tracheal tumours, two of which were osteochondromas. Both occurred in young dogs (3 and 4 months of age).…”

“…While this patient presented for intermittent wheezing, respiratory distress and stridor, other clinical signs observed by owners of affected dogs include dyspnea, coughing, change or loss of bark, cyanosis and in severe cases collapse 3 . Although tracheal osteochondromas are seen very infrequently, they are most commonly reported in patients under the age of 2 years 4 . A previous report described 10 patients with tracheal tumours, two of which were osteochondromas.…”
