Epidural lipomatosis with foci of hemorrhage and acute compression of the spinal cord in a child with CLOVES syndrome: illustrative case

Abstract

BACKGROUND Congenital lipomatous overgrowth, vascular malformations, epidermal nevi, spinal/skeletal anomalies, and/or scoliosis (CLOVES) syndrome is the most recently described combined vascular anomaly characterized by congenital excessive growth of adipose tissue, vascular malformations, epidermal nevi, and skeletal deformities. This condition exhibits a significant variability in clinical manifestations and a tendency for rapid progression and affects extensive anatomical regions. Information regarding the association of epidural lipomatosis with low-flow venous lymphatic malformations is rare, with few reports in the literature. OBSERVATIONS The authors present a case of a 6-year-old girl who was admitted to the emergency department complaining of rapidly progressing weakness in her lower extremities and partial loss of sensation in the inguinal area. Radiologically, an extradural mass was identified at the T2–6 level, causing acute spinal cord compression. Urgent decompression and partial resection of the mass were performed. Despite satisfactory intraoperative hemo- and lymphostasis, postoperative lymphorrhea/seroma leakage was encountered as a delayed complication and was managed conservatively. LESSONS CLOVES syndrome is characterized by the combination of various clinical symptoms, not all of which are included in the abbreviation, as well as a progressively deteriorating course, the emergence of new symptoms, and complications throughout the patient’s life. This necessitates ongoing monitoring of such patients.
