Extensive cervical truncal/upper extremity lymphatic venous malformations. There is redemonstration of relatively large multiseptated cystic and solid lesions bilaterally at the base of the neck, right more so than left, which are partially visualized. Descending multiple spaces in the neck and extending into the bilateral chest cavities, upper mediastinum, axillae, and right posterior chest wall. The dominant right-sided lesion have significantly decreased in size, compatible with history of debulking, with the largest cystic component measuring up to 2.1 x 1.4 cm superior to the right scapula (series 601 image 16). The lesions remain in close contact the major cervical vessels. An additional lesion also visualized posterior soft tissues of the back in the midline at the T3-T4 level, which do not appear significantly changed. There is no evidence of significant cervical lymphadenopathy based on size criteria. The thyroid and major salivary glands are unremarkable. The major cervical vessels are patent. The osseous structures are unremarkable. However, there is prominent epidural fat in the posterior cervicothoracic spine, without spinal cord compression. The airways are patent. The imaged intracranial structures are unremarkable. The imaged portions of the lungs are clear.
1. Interval debulking of the partly imaged extensive right-sided mediastinal, chest wall, and right lower neck lymphangioma related to CLOVES syndrome. Please refer to the separate chest MRI report for additional details.2. Multiple other neck lymphangiomas appear to have evolved, although comparison is limited due to differences in technique.3. Prominent epidural fat in the posterior cervicothoracic spine, without spinal cord compression, which may be related to the overgrowth syndrome.
