This case report describes a rare instance of spinal intradural müllerianosis in a 42-year-old woman presenting with three years of catamenial lumbago and sciatica. Surgical excision of a polypoid mass compressing nerve trunks revealed a lesion composed of endocervical, endometrial, and tubal glands within a smooth muscle nodule, confirming the diagnosis. The authors note that this uncommon presentation requires correct identification to allow for potential benefits from hormonal therapy. This paper is centrally about endometriosis — specifically, it presents a heterotopic manifestation of Müllerian tissue involving endometrial glands within the spinal canal, which is a rare form of extrapelvic endometriosis.

Abstract

Müllerianosis is a term used to indicate lesions composed of an admixture of two or three types of müllerian-derivation glands in heterotopic sites. In this report we describe a case of spinal cord müllerianosis which occurred in a 42-year-old woman. The patient had suffered from catamenial lumbago and sciatica of three years duration before undergoing laminectomy of L2-L3 with excision of a polypoid mass that compressed nerve trunks. At histological examination, the lesion was composed of endocervical, endometrial and tubal glands within a smooth muscle nodule. These features were consistent with a diagnosis of müllerianosis. This is a very uncommon form of presentation of müllerianosis that must be correctly identified since patients can benefit from hormonal therapy.
