“…However, caution is required as an ultrasonographic image will not be obtainable if an air bubble is present within in the contrast medium and is inadvertently injected into the lymph node. Brisson et al stated that if the mesenteric lymph node is moved during a laparoscopy procedure, then the contrast medium could leak around the injection point [3]. In our study, the contrast medium injected into the popliteal lymph node could be checked accurately with an ultrasound.…”

“…This may be due to the small population of dogs used because more thoracic ducts were counted with computed tomographic images at every anatomical level, although there was no statistically significant difference. However, patients do not need to be repositioned, images can be manipulated to better observe the target tissue, image contrast is vastly enhanced and small differences in contrast can be detected during computed tomographic scanning [3]. Lymphography using computed tomography for identification of the thoracic duct would be useful for ligation of the thoracic duct [4,12].…”

Lymphography is essential for evaluating the integrity of the thoracic duct and its branches, and several techniques, including pedal lymphography, and direct mesenteric lymphangiography, have been used to identify the causes of chylothorax in dogs.…”

ABSTRACT. The purposes of this study were to determine the optimal dose and delay time for lymphography by injection of Iohexol into popliteal lymph nodes and to assess images of computed tomography by the established protocol. Three different doses (30, 60 and 90 mgI/kg) of water-soluble iodinated contrast medium were injected into 15 popliteal lymph nodes of 10 adult beagles, and fluoroscopy was performed. Filling and duration of contrast media and the number of visible ducts from popliteal lymph nodes to the thoracic duct and its branches were recorded. CT lymphography was performed, and the number of visible thoracic ducts was compared with that found by radiographic lymphography. Radiographs obtained between 130 and 800 seconds after injection of contrast medium provided a detailed view of the thoracic duct. The dose of 60 mgI/kg was determined to enable quality diagnostic imaging without extranodal leakage in radiographic lymphography. There was no significant difference in the number of thoracic ducts between the two modalities at each anatomic location. However, CT lymphography provided images of the thoracic duct with better spatial resolution and without superimposition of surrounding tissue. The present study provides an adequate delay time and injection for identification of the canine thoracic duct, and therefore, this technique could be applied to diagnosis of disease associated with chest lymphatic drainage.KEY WORDS: CT, dog, Percutaneous ultrasound guided popliteal lymphograhy, thoracic duct.

“…Indirect signs of active lymphatic fistulas were increasing extravasations of contrast material and free abdominal fluid. The 3D gradient echo sequence with the highest planar resolution (TR = 8,(7)(8)8 ms, TE = 4,(2)(3)(4),3 ms, FA = 40 8, matrix size = 327 512) was best suited for distinct delineation of the lymphatic system and detailed demonstration of the thoracic duct fistulas. Intrathoracic leaks could not be demonstrated by MR lymphography due to reduced lymphatic flow or extravasated contrast medium at the abdominal puncture site.…”

“…Computed tomographic scans can provide detailed anatomical information, and oral contrast preparations for thoracic duct opacification have been described. 21 Magnetic resonance imaging scans can often delineate soft tissue planes better than computed tomographic scans and thus provide more anatomical detail. On T1-weighted images, lymphatics appear hypointense or as an intermediate signal.…”

T horacic duct cysts are uncommon entities that most commonly occur in the abdominal and thoracic segments of the thoracic duct; the rarest reported location is the cervical segment. The first case of a cervical thoracic duct cyst was reported in 1964, 1 and a review of the literature that was published in 1999 identified only 10 such cases. 2 We describe a patient with a thoracic duct cyst, review the relevant literature, and discuss the characteristics, treatment, and diagnosis of these lesions. REPORT OF A CASEA previously healthy 41-year-old man presented with a 2-year history of a progressively enlarging left supraclavicular mass. There were no symptoms associated with the mass. The patient's medical history was noncontributory except for the excessive use of tobacco and alcohol. Examination of his neck revealed a partially mobile, globular, nontender mass in the left supraclavicular fossa that measured approximately 5 cm in diameter. The mass was nonpulsatile and compressible. The findings of the rest of the head and neck examination were unremarkable. A computed tomographic scan of the neck and chest with contrast revealed a nonenhancing, fluid-filled 4ϫ3 cm mass in the left supraclavicular fossa that was partially compressing the left internal jugular vein (Figure 1). There was no evidence of adenopathy. The mass, which was exposed through a neck crease incision placed in the lower part of the left side of the neck, appeared to be cystic in consistency and was located above the clavicle immediately proximal to the junction of the thoracic duct and the internal jugular and subclavian veins. The cyst was connected to the internal jugular vein by 2 small tubular pedicles, which were carefully divided between liga-tures before excision of the mass. The partially aspirated contents, which appeared milky, were sent for analysis. The neck incision was closed over a suction drain that was removed the next day, and the patient was discharged from the hospital. There were no postoperative complications. Analysis of the fluid that was aspirated intraoperatively revealed a triglyceride level of 817 mg/dL (9.22 mmol/L). Pathologic examination showed an ovoid unilocular cyst whose wall was composed of fibrous tissue and smooth muscle, with adipose tissue and lymphoid aggregates on its outer surface. The luminal surface had focal areas covered by a single layer of flat cells (Figure 2), which stained positively with immunohistochemical markers for CD31, CD34, factor VIII, and keratin. No staining was present with epithelial membrane antigen or calretinin. This pattern of immunoreactivity is consistent with endothelial or lymphatic cells. The histologic sections, pattern of immunoreactivity, and high triglyceride level support the diagnosis of a thoracic duct cyst. COMMENTThe thoracic duct enters the left side of the neck posterior to the inominate artery and arches 3 to 4 cm above the clavicle. It lies anterior to the vertebral vessels, sympathetic trunk, and thyrocervical trunk and empties into the left internal jugula...
