Lymphomatoid Granulomatosis Involving the Lung and Brain in a Child: A Case Report

Lymphomatoid granulomatosis (LG) is a rare B-cell type angiocentric lymphoproliferative disease that can progress to extranodal lymphoma with high mortality. It most commonly affects the lungs, although extrapulmonary systems, including the brain and skin, can also be involved. LG in pediatric patients has been very rarely reported in the literature with limited imaging features. Herein, we report a pediatric case of LG involving the lung and brain with characteristic imaging findings.

Childhood lymphomatoid granulomatosis: a report of 2 cases and review of the literature

Lymphomatoid granulomatosis (LG) is a B-cell type lymphoproliferative disease. It mainly affects the lungs but may have extrapulmonary manifestations, especially in the central nervous system. The purpose of this study was to review the pediatric cases in the literature and add 2 new cases to the existing literature. A review of the literature was performed on children (0 to 18 years of age at diagnosis) with pathologically proven LG. We found 47 case reports, which, together with 2 new cases, were systematically analyzed. The median age was 12 years. The main symptoms were general, pulmonary, and neurological. Approximately one third of the patients were immunocompromised. High mortality rate was observed. Pediatric LG is a rare disease, which appears to be more frequently seen in immunocompromised patients, especially patients with leukemia. The disease has a high mortality rate; therefore, aggressive therapy according to a high-grade B-cell lymphoma protocol is justified.

Lymphomatoid granulomatosis: a rare cause of cavitatory lung disease in an HIV positive child

We present an unusual cause of lung cavitation and a neck mass in an HIV positive child, initially thought to be tuberculosis. This case report illustrates that the cause for cavitatory lung disease in immunosuppressed children has a large number of possibilities and careful investigation to determine the etiological agent is warranted.

Lymphomatoid granulomatosis with spinal involvement after childhood acute lymphoblastic leukemia

Lymphomatoid granulomatosis (LYG) is a lymphoproliferative disease involving the lungs most frequently; however, it may also involve the kidneys, skin and especially the central nervous system. Unique initial presentation of spinal involvement is extremely rare and epidural lesion of thoracic spine has not been reported. The prognosis for LYG has been reported to be poor, and there currently exists no satisfactory established treatment protocol. The purpose of this study is to report a case of successful treatment with surgery and rituximab combination therapy in thoracic spinal LYG.
