case_images: Sagittal magnetic resonance image of the thoracic spine shows multiple vertebral body lesions. T1-weighted (A) and T2-weighted (B) images show multiple hypointense masses.

case_images: T1-weighted and T2-weighted images throughout the thoracic and lumbar spine (Fig. 1). There was no evidence of spinal canal stenosis that could have caused numbness.
case_images: Contrast-enhanced computed tomography (CT) scan reveals a hypoattenuating lesion on the patient's right dorsal pleura (A), which shows no fluorodeoxyglucose uptake on positron emission tomography CT (B). The white arrow indicates the lesion.

case_images: A hypoattenuating lesion in the right dorsal pleura was detected (Fig. 2A), but there were no abnormal shadows in the lungs and no suspected tumor masses in other organs. Fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)-CT showed no remarkable 18F-FDG uptake in either the pleural lesion (Fig. 2B) or the bone lesions (not shown).
case_images: Histology of the right pleural lesion. Hematoxylin-eosin staining of the specimen revealed a marked proliferation of dilated lymphatic structures, which were consistent with the generalized lymphatic anomaly.

case_images: Hematoxylin-eosin staining of the biopsy specimen revealed a marked proliferation of complex anastomosing lymphatic canals (Fig. 3).
