“…Recently, there have been some reports on the evaluation of the thoracic duct or cisterna chyli using MDCT. Liu et al [3] reported a normal appearance of the distal (cervical) thoracic duct. According to their study, using MDCT, the distal thoracic duct was identified in the left side of the neck in 150 (55%) of 275 patients, and the mean diameter was 4.8 mm.…”

“…In the present study, however, ''complete'' visualisation in the upper section between the level of the aortic arch and confluence to the left subclavian vein or the left jugular vein was detected in only 14% of patients. Liu et al [3] evaluated the thoracic duct in only a portion of the confluence, and therefore the difference in visualisation frequencies between studies is probably due to the difference in range of evaluation. Low detectability for the thoracic duct in the upper section is probably due to the difficulty of differentiation between the thoracic duct and the adjacent vessels because of less fat tissue in this area.…”

“…Hayashi and Miyazaki [13] reported that an entire image of the thoracic duct was depicted in all six cases with a short echo spacing 3D half-Fourier fast spin echo sequence, without use of a contrast media. More recently, the [3] protocol of MR-thoracic ductography (MRTD) was introduced by Okuda et al [16]. They reported that MRTD is non-invasive and enables identification of the configuration and anatomical variation of the thoracic duct.…”

“…Currently, thin-slice and multiplanar reformation (MPR) images using multidetector row CT (MDCT) enable the understanding of detailed anatomy of various organs. Recently, there have been some reports regarding the evaluation of the thoracic duct and the cisterna chyli by using MDCT [3,4].…”

Objectives: The aim of this study was to evaluate the normal anatomy of the thoracic duct and cisterna chyli obtained by axial and multiplanar reformation (MPR) images of 1 mm slice thickness using multidetector row CT (MDCT). Methods: We evaluated the ability of MDCT to examine the normal anatomy of the thoracic duct and cisterna chyli. The axial and coronal images of thoracoabdominal MDCT images obtained in 50 patients (20 females and 30 males; mean age, 63.5 years; range, 32-81 years) were reviewed between January and October 2005. We excluded patients with malignant neoplasms, inflammation or vascular diseases (e.g. aortic aneurysm, aortic dissection) and those with a history of thoracoabdominal surgery. The thoracic duct was divided into three anatomical sections: the upper, middle and lower. We evaluated the degree of visualisation and the maximum size of the thoracic duct. We also evaluated the degree of visualisation, maximum size, configuration and location of the cisterna chyli. Results: Visualisation of the thoracic duct and cisterna chyli was almost 100% on axial and coronal images. The lower section of the thoracic duct was most clearly visualised among the three sections. There was little difference in the maximum size of the thoracic duct among the three sections. The cisterna chyli was most frequently located at the Th12 or L1 level, and the most common type was the ''straight thin tube type''. Conclusion: Axial and MPR images of 1 mm slice thickness using MDCT can clearly depict the thoracic duct and cisterna chyli.

La linfangioleiomiomatosis (LAM) es una enfermedad multisistémica asociada a mutaciones del gen TSC 2, que se presenta en forma esporádica (LMA-E) o asociada al complejo de esclerosis tuberosa (LAM-CET). La LAM cursa con enfermedad pulmonar relacionada con quistes en el parénquima. Sin embargo, los pacientes con LAM-E pueden evidenciar alteraciones mediastinales, retroperitoneales y renales, con adenomegalias, linfangioleiomiomas y angiomiolipomas.Presentamos el caso de una paciente con LAM-E y enfermedad pulmonar quística asociada a linfangioleiomiomas retroperitoneales y pélvicos.

Review of thoracic duct anatomical variations and clinical implications

et al. 2013

The thoracic duct (TD) transports ingested fat, drains lymph from the gastrointestinal vascular bed, and delivers the lymph to central veins in the neck. Preliminary evidence suggests that diversion of TD lymph may mitigate the severity of end-organ dysfunction in critical illness. Variations in the anatomy of the TD may determine whether reliable and safe cannulation of the duct, a necessary step for diversion, is possible. A systematic review was undertaken using the Google Scholar, MEDLINE, PubMed, and Scopus databases until 31st March, 2013. Both English and non-English articles were searched for, and surgical, cadaveric, and radiologic studies were included. Fifty-seven articles from the past 102 years were retrieved. There are significant variations in the anatomy of the TD in terms of its formation at the cisterna chyli, its course through the thorax, and its termination in the venous system. The most common site of termination is at the internal jugular vein (46%), followed by the jugulosubclavian angle (32%), and the subclavian vein (18%). An improved understanding of the anatomy of the TD would help surgeons to avoid inadvertent injury and potentially afford new opportunities for diagnosis and intervention in patients with critical illness.

Normal CT Appearance of the Distal Thoracic Duct

Abstract: Familiarity with the normal CT appearance of the distal thoracic duct can be helpful in differentiating a normal duct from pathologic lesions of the lower neck, such as lymphadenopathy.
