CTICasesHemangiolymphangiomatosis (Gorham's Disease)
Imaging findings
A man with generalized bone disease, including enlarged bones and pathologic fractures, presented with diffuse, low-attenuation masses in the mediastinum (paraspinal and along the thoracic duct), spleen, and a large abdominal mass, all containing scattered calcifications (phleboliths).
Key takeaways
Hemangiolymphangiomatosis is a rare, complex disorder characterized by the proliferation of lymphatic and vascular channels, often involving multiple organ systems including bone, soft tissues, and viscera. The presence of phleboliths within the lesions suggests a combined hemangiomatous and lymphangiomatous component. When bone is involved, it can lead to osteolysis and pathologic fractures, a condition sometimes referred to as Gorham's disease.
