Anatomy is the great ocean of intelligence upon which the true surgeon must sail. chylous cyst: Presenting as supraclavicular mass

Cysts of the thoracic duct located in the supraclavicular region are uncommon. To date only 12 cases in this topographic area have been described in the literature. Lymphocoele of the thoracic duct, alternatively referred to as a thoracic duct cyst, is an uncommon abnormality that can present rarely as a left neck mass arising from the supraclavicular fossa. Recognition of the aetiology of such a neck mass on imaging is crucial to avert unnecessary intervention and, where surgical intervention is planned, to avoid both unexpected findings at surgical exploration and secondary complications. We present such a case of a cervical neck mass. Thoracic duct cyst are relatively unclear etiology. B The first reported case of thoracic duct cyst was in1964 by steinbergetal. Since that time, only 32 cases have been reported in the literature with the largest case series consisting of only 5 patients. 2 The most common approach to managing these lesions is surgical excision with ligation of the thoracic duct. We report a case of thoracic duct cyst involving the left supraclavicular fossa. Keyword: Cyst.
