Spontaneous spinal epidural abscess in an adolescent patient: A case report and literature review

Abstract

Introduction: Spinal epidural abscess (SEA), particularly the spontaneous variant, is a severe and rare condition often associated with vertebral osteomyelitis, hematogenous infections, and spinal interventions, leading to severe neurological damage and disabilities. Although more common in adults, spontaneous SEA (SSEA) in adolescents is extremely rare but represents a significant risk, as presented here.

Presentation of case: A 16-year-old boy presented with progressive back pain, uncontrolled fever, and paresthesia in the right lower extremity. Despite the absence of common risk factors, SEA was diagnosed at the L4-L5 level. Laboratory results revealed leukocytosis and elevated levels of inflammatory markers. Magnetic resonance imaging (MRI) confirmed the diagnosis of SEA, and surgery revealed Group A Streptococcus in the abscess. The patient showed significant improvement after laminectomy and a six-week course of intravenous cefazolin.

Discussion: SSEA often presents with nonspecific symptoms, leading to delayed diagnosis and treatment. The gold standard for diagnosis is MRI, and typical treatment involves antibiotic administration and surgical decompression. The importance of maintaining a high index of suspicion for SEA in adolescent patients presenting with back pain and fever, even in the absence of common risk factors or sources, is highlighted.

Conclusion: We report the infrequent manifestation of SEA in an adolescent patient, and the difficulties in the diagnosis and treatment thereof. Despite these common risk factors, SEA should be considered as a differential diagnosis in adolescents with back pain and uncontrolled fever. Prompt diagnosis, early surgical intervention, and appropriate antimicrobial therapy are vital to improve patient outcomes and prognosis.
