Rapid growth and regression of intracranial meningiomas in lymphangioleiomyomatosis: case report.

BACKGROUND

Lymphangioleiomyomatosis is a progressive interstitial lung disease that affects young women. It has been suggested that estrogens play a role in its evolution, and progesterone therapy is often provided in these cases.

CASE DESCRIPTION: We present a case of a postmenopausal woman with LAM treated with progesterone; subsequently, rapid growth of multiple intracranial meningiomas was observed. One prominent lesion was excised, and 3 other lesions regressed spontaneously over 2 years.

CONCLUSIONS

This is a rare case of a non-pregnancy-related regression of meningiomas in a woman affected by LAM. The significance of this association and the hormonal treatment of the disease are discussed.
