A 3-year follow-up case report of rare intramuscular schwannoma of psoas major: Insights into progression and management

In subsequent clinical practice, we will pay more attention should be paid to patients with low back pain accompanied by nerve root symptoms. In particular, when anti-inflammatory treatment is ineffective, space-occupying lesions should be excluded. Follow-up may be reasonable, especially for elderly patients whose symptoms are tolerable and have surgical contraindications. More follow-up data are needed to help us understand the development of schwannomas in the psoas muscle. This case is of great significance for understanding the progression of intramuscular schwannomas of the psoas major.
