“…Previous reports of caudal mediastinal cysts and paraesophageal abscesses have demonstrated similar imaging findings in all affected dogs . Because of this repeatable appearance, the constancy of imaging signs may be due to some underlying anatomic reason, like involvement of the mediastinal serous cavity.…”

“…Literature review identified a single case series and five case reports describing a total of 12 dogs, 10 of which were called paraesophageal abscesses and two were called mediastinal cysts 2. [1][2][3][4][5][6] This group was comprised of three neutered males, five intact males, and four intact females. All dogs were medium-to-large breed, and three were younger than 2 years.…”

“…In both dogs, the MSC (*) is severely expanded and sparsely (A) or completely (B) lined by different amounts of contrast enhancing, lobulated to frond‐like soft‐tissue proliferations that project into the fluid‐filled lumen. In both images, the caudal vena cava and aorta are marked for anatomic reference. In image A, an esophageal tube (arrow) is present and the caudal vena cava is compressed.…”

The mediastinal serous cavity is a normal anatomic space in the caudal mediastinum. Aims of this anatomic and case series study were to describe the signs of pathologic expansion of the mediastinal serous cavity observed during computed tomography (CT), review the underlying anatomy, perform a literature review, and evaluate the medical records of several dogs with mediastinal serous cavity empyema (paraesophageal empyema). The mesothelial lined mediastinal serous cavity is a cranial extension of the omental bursa, separated from the peritoneal cavity by the diaphragm, in the dorsal part of the caudal mediastinum, to the right of the esophagus, between the heart base and diaphragm. In five adult, large-breed dogs with surgically and histologically confirmed paraesophageal empyema, macroscopic plant material was found at surgery in two dogs, adherence to adjacent lung was present in three different dogs, accessory lobectomy was performed in two dogs with subacute-chronic pyogranulomatous pneumonia, and one dog had concurrent pyothorax and mediastinitis, but none had esophageal abnormalities. This study expands our understanding of the pathogenesis and basis for the imaging appearance of paraesophageal empyema in dogs by clarifying the underlying anatomic structures that direct development of this condition. The term empyema accurately describes this condition because the purulent material accumulates within an existing body cavity. The study also provides initial evidence that the development of paraesophageal empyema might be due to local extension of lung disease, such as foreign body migration or pneumonia. Computed tomography was helpful for diagnosis, assessing size, and determining the spread of disease.

“…The largest veterinary case series to date reported 7 dogs, all of which were managed with a surgical approach 6 . There is an additional report reporting a successful surgery in an Irish Setter; otherwise, the literature on this condition in dogs is sparse 7 . The condition has been reported in 2 cats.…”

Objective: To describe a novel technique for paraesophageal abscess drainage in a dog.Case summary: A 6-year-old dog presented for pyrexia of unknown origin, subsequently confirmed to be due to a paraesophageal abscess. This was managed by the ultrasound-guided placement of a thoracostomy tube into the abscess, allowing drainage to be performed. This led to clinical resolution and, at an 8-month follow-up, the dog continued to do well. New or unique information provided: Paraesophageal abscessation is typically managed with surgical intervention, which carries inherent risks and complications. This report describes a novel technique that did not require general anesthesia or invasive surgical intervention, achieving clinical remission without any adverse effects. It also summarizes the current literature available on this condition. K E Y W O R D Scanine, cyst, thoracostomy, ultrasound A 6-year-old neutered female German Shorthaired Pointer weighing 23.9 kg presented to the primary care veterinarian with chronic weight loss and an acute history of productive coughing that was managed with meloxicam (0.2 mg/kg, SC) and parenteral vitamin B 12 (500 µg/kg, SC). a,b The dog became progressively hyporexic, and a course of oxytetracycline (25 mg/kg, PO, q 12 h) was started. c At re-presentation 72 h later, the dog was pyrexic at 39.9 • C and estimated to be 5-7% dehydrated. A CBC identified a neutrophilia at 17.01 × 10 9 /L (17 010/µL) (reference interval [RI], 2.95-11.64 × 10 9 /L [2950-11 640/µL]) with suspected band neutrophil presence on the automated analyzer and a monocytosis of 2.21 × 10 9 /L (2210/µL) (RI, 0.16-1.12 × 10 9 /L [160-1120/µL]). Right lateral radiographs of the thorax were performed (Figure 1). On the lateral thoracic projection, there was a large, rounded, well-demarcated soft tissue mass in the caudoventral thorax, extending from the 8th to the 12th intercostal space, superimposed on the cardiac silhouette and diaphragm. At this point, the dog was referred for further evaluation.

A 15-year-old domestic cat presented with restrictive dyspnoea and pyrexia. Thoracic radiographs and computed tomography (CT) revealed a caudal mediastinal paraesophageal empyema associated with pyothorax, pleuritis and pericardial effusion. No foreign body was visible. The bacteriology was positive for Fusobacterium nucleatum. Medical treatment was initiated and consisted of bilateral drainage/lavage of the pleural cavity and intravenous amoxicillin/clavulanic acid followed by oral administration.A second CT scan performed on Day 7 showed regression of the lesion and confirmed the effectiveness of the medical treatment. Thoracic drains were removed on Day 8, and antibiotic treatment stopped 3 weeks postdiagnosis. A CT scan performed at 6 weeks postdiagnosis revealed complete regression of the lesions.
