Cerebral lymphomatoid granulomatosis

Area of Science:

• Neurology
• Pathology
• Oncology

Background:

• Lymphomatoid granulomatosis (LG) is an uncommon lymphoproliferative disorder.
• It is characterized by angiocentric and angioinvasive cellular infiltrates, typically affecting the lungs.
• Central nervous system (CNS) involvement occurs in 20% of LG cases, but primary cerebral LG is rare.

Purpose of the Study:

• To review the clinical features, laboratory investigations, neuroimaging, and pathological findings of primary cerebral LG.
• To highlight the diagnostic challenges associated with primary cerebral LG, especially when extracerebral disease is absent or occult.
• To discuss the potential treatability of this rare condition.

Main Methods:

• Review of six cases of cerebral LG.
• Analysis of clinical presentations.
• Evaluation of laboratory data, neuroimaging studies (e.g., MRI, CT), and neuropathological findings.

Main Results:

• Primary cerebral LG presents with diverse neurological manifestations.
• Diagnosis can be delayed due to the absence or occult nature of extracerebral disease.
• Neuroimaging and pathological findings are crucial for accurate diagnosis.

Conclusions:

• Cerebral LG, though rare, is a distinct entity that requires prompt diagnosis and treatment.
• Multidisciplinary evaluation involving neurology, radiology, and pathology is essential.
• Early recognition can lead to better patient outcomes.
