[Jugular vein thrombosis: a case report].

Thrombosis of the internal jugular vein is now rare but was well-known in the pre-antibiotic era, when it was associated with fulminant infections of the head and neck. Now the two major causes of jugular thrombosis are central venous catheterization and intravenous drug use. The clinical findings are a non-specific, painful, poorly delimited mass in neck that often is confused with an abscess or metastasis. CAT is necessary for diagnosis. We report a case secondary to central venous catheterization in which the clinical manifestations appeared three days after removing the catheter. The differential diagnosis of regional inflammations is described.
