CT features of generalized lymphangiomatosis in adult patients

Objective: The objective was to present computed tomographic (CT) findings of generalized lymphangiomatosis in young adults that was at first misdiagnosed with malignancy. Materials and methods: We reviewed the clinical and radiological findings of three young adults who had histologically confirmed generalized lymphangiomatosis. Results: Bony lesions were cystic forms and appeared as variably sized, well-circumscribed, irregular, microlobulated-contour, multiseptated masses. Lymphangiomas involving soft tissue were similar to bony lesions on CT. Conclusion: CT features of generalized lymphangiomatosis may be useful to prevent invasive procedures in young subjects. Generalized lymphangiomatosis involving bones in young adults shows less extensive and aggressive osteolytic pattern than known features in child.
