Myopericytoma of the thoracic spine in a pregnant woman: a case report on the management of a rare neoplasm.

Myopericytomas are perivascular myoid neoplasms that rarely exhibit malignant characteristics. They usually arise in the dermis or subcutaneous tissue and exceptionally involve deep soft tissues, with spinal localization being rare. We report the case of a previously healthy 32-year-old pregnant woman who presented with pain in the interscapular region and progressive loss of lower limb strength. Magnetic resonance imaging revealed a solid neoplastic mass at the T3 level, with spinal canal invasion and spinal cord signal abnormalities. The pregnancy was terminated, followed by lesion embolization, decompressive laminectomy, and local radiotherapy. The patient completely recovered from her neurological symptoms. Thoracic spine myopericytomas are rare and have been poorly reported in the literature. No studies have described the aforementioned neoplasm in a pregnant patient. We report this case because of its peculiarity, evolution, and outcome.
