Successful Treatment of Vaginal and Pelvic Microcystic Lymphatic Malformation with 50% Ethanol Injection via Lymph Node Angiography.

BACKGROUND

Clinically, surgical treatment and sclerotherapy are the main treatments for lymphatic malformation (LM), but the diagnosis and treatment of microcystic LM has numerous pitfalls. Microcystic LM within the vagina and pelvis is not easily visible, and there are many side effects of treatment. Lymphangiography, a relatively old method of identifying diseases of the lymphatic system, has been rarely used in clinical settings because of the difficulty of performing this test. In this article, we describe the use of a special lesion site adjacent to the nearby lymph nodes for the treatment of vaginal and pelvic microcystic LM.

CASE: Lymphangiography was performed using lymph node aspiration combined with direct local puncture of the lesion, guided by the injection of iodine oil, which can produce a better outcome and more complete removal of the lesion. Finally, sclerotherapy was conducted using a low concentration of 50% ethanol with good fluidity, which covered the lesion to a great extent. This methodology was shown to be effective in treating children with vaginal and pelvic microcystic LM.
