The objective of this study is to report a case of deep endometriosis of the paralumbar muscles (psoas, multifidus, and erector spinae) and review existing literature on its management. A 34-year-old female with a history of endometriosis was seen for infertility. Paralumbar muscle masses seen on computed tomography (CT) scan were sampled, confirming endometriosis. Gonadotropin-releasing hormone agonist was given for 2 months. The patient was primed for assisted reproduction. A literature review was conducted to provide an understanding of paralumbar muscle endometriosis. To our knowledge, this is the first reported case of multifidus and erector spinae muscle endometriosis and fifth case of psoas muscle endometriosis. Because the available information is scarce, data from the existing literature on deep endometriosis may aid in the diagnosis and management. Magnetic resonance imaging and CT scan are essential imaging techniques to map lesions. Excision seems prudent, but the approach should be individualized depending on the patient's presentation and her preferences.
