Lymphomatoid granulomatosis (CNS manifestations)
Updates to Article Attributes
Lymphomatoid granulomatosis of the central nervous system is uncommon, but represents the second most common site of involvement in patients with systemic lymphomatoid granulomatosis, after the lungs, which are most commonly involved.
For a general discussion of the underlying condition, including epidemiology and pathology, please refer to the articlelymphomatoid granulomatosis.
Clinical presentation
Neurologic symptoms are fairly common, seen in around 30% of cases, usually in the setting on systemic or cutaneous symptoms 1.
Radiographic features
MRI is the modality of choice for assessing patients with suspected lymphomatoid granulomatosis.
MRI
Appearances are very variable with lesions seen in all compartments (supra- and infratentorial) and demonstrating a wide range of morphology.
Generally, lesions were located in the periventricular white matter, but can extend to involve cortex.
Punctate or linear T2 hyperintensities within perivascular spaces are also characteristic and show contrast enhancement1,2. Larger lesions may be solid or demonstrate ring enhancement. They have variable surrounding oedema and may be associated with leptomeningeal enhancement 1.
