Isolated CNS relapse of medullary aggressive high-grade B-cell lymphoma on F-FDG-PET/CT.

Eur J Hybrid Imaging 2022 May 3;6(1). Epub 2022 May 3.

Radiology Department, Mater Misericordiae University Hospital, Eccles Street,, Dublin 7, Ireland.

This is a case of high-risk, aggressive, high-grade medullary B-cell lymphoma presenting with new onset of neurological dysfunction following initial complete response to the standard chemoimmunotherapy. A whole-body re-staging PET using fluorodeoxyglucose (F-FDG) integrated with computed tomography (FDG-PET/CT) performed with clinical suspicion of arachnoiditis, eloquently demonstrated unequivocal multifocal FDG uptake by the spinal cord without evidence of systemic recurrence, leading to a clinical diagnosis of secondary CNS lymphoma, which is a rare complication of DLBCL with ominous prognosis. Four cycles of Modified-MATRIX protocol resulted in a halt in fulminant course of the disease and the patient experienced slight reversal of the neurological deficits, although not deemed clinically fit for a repeat FDG-PET/CT due to his poor general well-being.

Venous congestion as a central mechanism of radiculopathies.

Joint Bone Spine 2022 03 12;89(2):105291. Epub 2021 Oct 12.

Rheumatology Unit, Hôtel-Dieu, Nantes University Hospital, 1, Place Alexis, 44093 Nantes-Cedex 01, France.

Compression of roots/nerves can disrupt some of their functions, but does not necessarily cause pain. This is illustrated by the frequency of nearly asymptomatic spinal stenosis or disc herniations. In fact, pain of radiculopathies (and nerve entrapments) may mostly be the consequence of intraneural oedema induced by microscopical venous stasis around roots/spinal ganglia (or nerves) not or poorly shown by imaging.

[Treatment of syringomyelia in patients with arachnopathy within craniovertebral junction].

Zh Vopr Neirokhir Im N N Burdenko 2021 ;85(1):10-18

Pirogov Russian National Research Medical University, Moscow, Russia.

One of the causes of syringomyelia is arachnopathy following an infectious or non-infectious inflammation of the arachnoid membrane. It is extremely rare that adhesive arachnoiditis develops within the occipital cistern and impairs cerebrospinal fluid flow from the foramen of Magendie, along posterior cerebellar surface and into spinal subarachnoid space. These process result syringomyelia. Read More
