Case report: computed tomography of generalized lymphangiomatosis and chylothorax

Chylothorax in infants and children

Chylothorax, the accumulation of chyle in the pleural space, is a relatively rare cause of pleural effusion in children. It can cause significant respiratory morbidity, as well as lead to malnutrition and immunodeficiency. Thus, a chylothorax requires timely diagnosis and treatment. This review will first discuss the anatomy and physiology of the lymphatic system and discuss various causes that can lead to development of a chylothorax in infants and children. Then, methods of diagnosis and treatment will be reviewed. Finally, complications of chylothorax will be reviewed.

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.

Linfangiomatose pulmonar: relato de dois casos

A linfangiomatose, doença rara e de origem controversa, ocorre em indivíduos de todas as faixas etárias, predominando entre os mais jovens, sem predileção por sexo. Comumente cursa com envolvimento torácico, porém órgãos como ossos, baço e fígado podem ser acometidos. Histologicamente, o envolvimento pulmonar cursa com proliferação, anastomoses complexas e dilatação secundária do sistema linfático. Clinicamente, a apresentação é variável. Os achados radiográficos podem ser sugestivos e o diagnóstico é definido pela histologia. Relatamos dois casos da doença; uma das pacientes era oligossintomática e encontra-se em tratamento; na outra, a doença foi mais agressiva e o diagnóstico muito tardio, culminando em óbito.

Angiomatosis of bone and soft tissue: a spectrum of disease from diffuse lymphangiomatosis to vanishing bone disease in young patients

The application of cross-sectional imaging in the investigation of patients with angiomatosis reveals that lymphangiomatosis and vanishing bone disease should not be considered as separate entities, but rather as a spectrum of disease. We present a pictorial review of eight patients demonstrating the manifestations of soft tissue and bony involvement. We highlight a subgroup of patients with chyloid pleural effusions who have a poor prognosis.

Giant benign cystic peritoneal mesothelioma: US, CT, and MRI findings

Benign cystic peritoneal mesothelioma (BCPM) is a rare tumor, primarily affecting young women; approximately 130 cases have been described mainly in the pathological and surgical literature. We present imaging findings of a giant BCPM in a male patient and discuss the radiological differential diagnosis with a brief review of the literature.
