Nonsurgical integrative Korean Medicine treatment of discal cyst

Abstract

Rationale: Discal cysts are rare lesions characterized by pain caused by neurogenic compression with similar symptoms as those of disc herniation. This study aims to report the spontaneous regression of discal cyst achieved through nonsurgical integrative Korean Medicine treatment and the clinical epidemiological features of discal cyst cases collected from 4 institutions. Patient concerns: A 31-year-old woman had low back pain and radiating pain equivalent to a numeral rating scale (NRS) of 8 and had limitations in daily work and activities. Diagnoses: The patient was diagnosed as having discal cysts that compressed the left S1 based on findings of L-spine magnetic resonance imaging (MRI) performed at our hospital. Interventions: The patient received nonsurgical Korean Medicine treatment and after 24 days of treatment in the hospital, she underwent 16 additional treatments as an outpatient. Outcomes: Spontaneous regression was confirmed in the L-spine MRI follow-up at 36 days and 99 days after the initial test, and the patient underwent once-a-week follow up to examine NRS, Oswestry Disability Index (ODI), EuroQol-5 Dimensions (EQ-5D), and fear-avoidance beliefs questionnaire (FABQ) after 4 weeks, and 2, 3, and 6-month follow-ups after that. The patient was discharged in a painless condition, and she was able to carry on for 5 months without increased pain. Lessons: Discal cysts are more rapid progress than disc herniation, it seems valid to attempt nonsurgical treatment. Epidemiologically, this is the first study to present the clinical epidemiological characteristics of discal cysts, it would provide valuable information to clinicians who treat and study discal cysts.
