Teaching Point: White matter reversal on diffusion-weighted magnetic resonance imaging is indicative of delayed post-anoxic encephalopathy. This manifests sooner in young infants than in adults.
RESUMO
Teaching Point: A submucosal bladder wall lesion with high signal on T2-weighted MRI warrants blood and urine analysis to rule out a paraganglioma.
RESUMO
Bone and soft tissue sarcomas are uncommon tumors that can occur within the upper extremity as well as elsewhere within the body. However, certain histopathological subtypes have increased affinity for the upper limb and even certain sites within the arm and hand. Other benign masses and tumor mimics, such as infection and traumatic lesions, are more common and imaging appearances can sometimes overlap with malignant lesions making diagnosis difficult. In this article, we explore the current options for imaging of these lesions as well as typical imaging appearances of the more common upper limb tumors.

Although plain radiographs of the chest are usually requested to evaluate the heart, lung, and mediastinum, many bone and soft tissue, metabolic, and congenital lesions can be visible presenting as surprising lesions. Thorough analysis of the lesion characteristics on the chest radiograph, eventually in conjunction with more advanced imaging techniques and in combination with the clinical findings, will lead to the correct diagnosis.

Neurolymphomatosis represents a peripheral lymphomatous neural infiltration and is a relatively rare condition. Histopathologically, most patients are demonstrated to have non-Hodgkin lymphoma. A 27-year-old man with a history of HLA-B27-positive ankylosing spondylitis and diffuse large B-cell lymphoma was referred for the investigation of a severe neuropathic pain radiating down his right hip and posterior thigh for 1 month. This report describes the diagnosis and therapy response assessment in a relapsing aggressive non-Hodgkin lymphoma on an F-FDG PET scan.
