Simultaneous Fungal and Microbial Infection in Neonate with Multiple Lumbosacral Abscesses: A Case Report

Background: Lumbosacral abscesses in neonates are an uncommon yet significant medical condition, often linked with congenital anomalies or immunodeficiency disorders. The complexity of these infections is exacerbated when they involve multiple abscesses and/or coexist with simultaneous microbial and fungal infections. This report presents a unique case of a neonate who developed multiple lumbosacral abscesses due to mixed bacterial and fungal infections, a scenario not previously documented in the literature. Case Report: An 8-day-old male neonate was delivered via normal vaginal delivery at 36 weeks and 5 days without reported maternal complications. Initial symptoms included irritation and cutaneous lesions in the genital and lumbosacral areas, which progressively worsened despite topical treatments and antibiotics administered at initial healthcare visits. Upon hospitalization, the patient exhibited multiple lumbosacral abscesses, ranging from 1.5 to 8 cm, alongside systemic signs such as mild fever and irritability. Laboratory analysis revealed elevated inflammatory markers (erythrocyte sedimentation rate=21 mm and C-reactive protein=27 mg/dL) and positive KoH smears indicating potential fungal presence. Pathogen identification through culture showed Staphylococcus aureus, Klebsiella, and E. coli, alongside fungal infection. Imaging studies ruled out spinal canal involvement, and a comprehensive treatment involving antifungal therapy (fluconazole) and broad-spectrum antibiotics (Cefotaxime and Vancomycin) was initiated. The patient's condition improved post-intervention, and he was discharged after two weeks. Conclusion: This case emphasizes the diagnostic and management challenges posed by simultaneous fungal and bacterial infections in neonates. Co-infections can complicate clinical presentations, prolong hospitalization, and necessitate rigorous diagnostic and therapeutic strategies. Accurate identification of pathogens and the selection of appropriate antimicrobial agents are imperative for effective management. Despite a successful outcome in this instance, the absence of follow-up underscores the necessity for consistent post-discharge monitoring, particularly in vulnerable populations. Continued research is essential to better understand these co-infections and improve clinical outcomes in neonatal care.
