MR‐lymphangiography identifies lymphatic pathologies in patients with idiopathic recurrent cervical swelling

Abstract

Abstract Background Idiopathic recurrent cervical swelling may be caused by lymphatic abnormalities. Methods Ten patients (9 females, mean age 51.2 ± 7) with idiopathic recurrent cervical swelling underwent MR‐lymphangiography (MRL). MR‐lymphangiograms were evaluated regarding lymphatic anatomy and flow. Individualized treatment was recommended according to MRL‐findings. Results 8/10 patients presented with left‐sided, 2/10 with right‐sided swelling. Pathological lymph‐flow was identified in all cases: thoracic duct dilatation in patients with left‐sided and right lymphatic duct dilatation in right‐sided swelling, accessory thoracic lymphatics in 7/10 and reflux in 8/10 cases. In two cases, a lymphatic thrombus was identified. After treatment, symptoms resolved completely in 6/10 cases and partially in 1/10 cases. The remaining three patients have intermittent swellings but have no treatment wish. Conclusion Idiopathic recurrent cervical swelling can be caused by lymphatic anomalies. MRL displays impaired lymphatic drainage, lymphatic vessel dilatation, and chylolymphatic reflux as hallmarks of this condition and may aid in targeted treatment planning.
