Imaging findings of childhood B-cell lymphoblastic lymphoma in the mental region: a case report

Abstract

Lymphoblastic lymphoma (LBL) is an uncommon neoplasm that accounts for about 5% of all non-Hodgkin's lymphomas. Approximately 90% of LBLs are of immature T-cell lineage, with B-cell lymphoblastic lymphoma (B-LBL) accounting for only about 10%. Owing to infrequency, the clinicopathological features and the imaging findings of B-LBL are not well defined. LBLs frequently affect extranodal sites. The most common site is the skin, followed by the bone, and the head and neck region is rarely involved. We report herein a case of childhood B-LBL occurring in the mental region, with emphasis on the findings of several imaging studies, including contrast-enhanced CT, MRI and fluorodeoxyglucose-positron emission tomography/CT.

Successful Treatment for Adult Precursor B-Cell Lymphoblastic Lymphoma Involving Central Nervous System Monitored by 18F-Fluorodeoxyglucose PET/CT Imaging

“…PBLL only accounts for 10-25% of all PLL and typically presents with subcutaneous, soft tissue, bone, and lymph node disease in children or young adults. Primary uncommon lesions of PBLL in testicles, localized skin, pancreas, and musculoskeletal system on 18 F-FDG PET imaging were reported, with SUV max ranging from 3.7 to 19.1 (3)(4)(5)(6)(7)(8)(9). Besides that, there are also case reports with initial symptoms of ovaries, retroperitoneum, tonsil, uterus, stomach, colon, mediastinum, and both lytic and blastic bone lesions (10)(11)(12)(13).…”
