Imaging of Burkitt lymphoma in pediatric patients

The imaging procedures utilized at presentation in the diagnostic work-up of 19 children with Burkitt lymphoma were reviewed. The distribution of disease was compared to other tumors of childhood so that the most valuable modalities could be identified. Burkitt lymphoma is a rapidly growing tumor in the child, making it essential to suggest the diagnosis as quickly as possible so that biopsy and treatment can be instigated. The primary area of involvement was abdominal (15 of 19), gastrointestinal, intraperitoneal adenopathy, hepatic and pancreatic without retroperitoneal adenopathy. Pleural effusions were common without hilar and mediastinal adenopathy. This is in contrast to other tumors of childhood where mediastinal and hilar disease in the chest and retroperitoneal node involvement in the abdomen are common. Thus sonography is an excellent imaging modality, easily identifying the extent of the disease and so suggesting the diagnosis.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46683/1/247_2006_Article_BF02388718.pd

Pseudoneoplastic lesions of the testis and paratesticular structures

Pseudotumors or tumor-like proliferations (non-neoplastic masses) and benign mimickers (non-neoplastic cellular proliferations) are rare in the testis and paratesticular structures. Clinically, these lesions (cysts, ectopic tissues, and vascular, inflammatory, or hyperplastic lesions) are of great interest for the reason that, because of the topography, they may be relevant as differential diagnoses. The purpose of this paper is to present an overview of the pseudoneoplasic entities arising in the testis and paratesticular structures; emphasis is placed on how the practicing pathologist may distinguish benign mimickers and pseudotumors from true neoplasia. These lesions can be classified as macroscopic or microscopic mimickers of neoplasia

Computed tomography imaging of subpleural lipoma in two men: two case reports

INTRODUCTION: Subpleural lipomas are very rare pleural lesions and are often discovered incidentally in asymptomatic patients on conventional radiographs. CASE PRESENTATIONS: We report two cases of subpleural lipomas and describe their imaging characteristics on chest radiographs and computed tomography. We describe the cases of two Caucasian men, aged 77 and 62 years old. CONCLUSIONS: For non-invasive diagnostic investigation, computed tomography enables the identification and quantification of these tumors due to their characteristic fat attenuation
