Ender Topal A.2024-04-242024-04-2420101306-7656https://hdl.handle.net/11468/24633Jugular vein distention as a neck mass is seen rarely and mostly the cause is tumoral invasion or intravascular trombosis. Tumoral invasions occur through metastatic lymph nodes or regional tumors. Distant neoplasms may cause also trombosis by creating coagulopathy or by pressure of lymphadenopathy. In this case, internal jugular vein was distended due to metastatic adenocarcinoma whose origin has not been found. There was not metastatic lymph node, regional tumor or intravascular trombosis. In English literature, no distant metastasis to jugular vein has been reported and from this aspect, this case may be the first one. As a conclusion, jugular vein occlusions must not be interpreted directly in favor of thrombus, even in the absence of regional primary tumor or metastasis, and in case of any doubts, further tests must be performed.
