Closing in on CLOVES: A Pictoral Review

Purpose or Case Report: Although rare, CLOVES syndrome, a PIK3CA-related congenital overgrowth disorder, presents radiologists with opportunity for vital diagnostic and treatment planning. CLOVES syndrome is characterized by Congenital Lipomatous Overgrowth of the trunk, Vascular malformations, Epidermal naevi, and Skeletal and Spinal anomalies. Multimodal imaging findings can help distinguish CLOVES from other overgrowth syndromes such as Proteus syndrome and Klippel-Trenauny syndrome. We present multimodal imaging of four patients with CLOVES syndrome which demonstrate characteristic findings:

- Thoracic lipomatous hyperplasia, a key sign of CLOVES syndrome in which predominantly thoracic lipomatous masses grow in the subcutaneous tissues and invade the pleura, mediastinum, and upper abdomen, often with superficial vascular malformations
- Renal anomalies, including agenesis, hypoplasia, hydronephrosis, and cysts.
- Vascular malformations, including venous, venolymphatic, and lymphatic malformations
- Spinal cord defects, including spina bifida, medullary arteriovenous shunts, and congestive myopathy of the paravertebral venous plexus

Management of CLOVES syndrome focuses on debulking of lipomatous masses, treatment of clinically significant vascular malformations, and medical management of renal and neurologic sequelae. To that end, the role of the radiologist is accurate diagnosis of the syndromic pattern, isolation of the extent of lipomatous masses for pre-operative planning, and identification of renal and spinal cord anomalies.

The purpose of the poster is to:

1. Briefly review the types of congenital overgrowth disorders as demonstrated in various imaging modalities.
2. Focus on characteristic imaging findings of CLOVES syndrome.
3. Review the benefits and disadvantages of various imaging modalities.
4. Identify the most relevant radiologic findings for surgical, interventional and medical management.
