Case of Primary Leptomeningeal Lymphoma Presenting with Papilloedema and Characteristics of Pseudotumor Syndrome

Mai Takagi et al. Neuroophthalmology. .

Abstract

The authors describe an immunocompetent, 50-year-old man who complained of a daily transient blurring of his vision with bilateral papilloedema. His visual acuity was 20/20 OU, and the blind spot was enlarged bilaterally. There was intracranial hypertension, but imaging for systemic and brain tumours were negative. These findings suggested a diagnosis of the pseudotumor syndrome. However, MRI showed leptomeningeal enhancement, and acetazolamide successfully resolved his visual symptoms and papilloedema. Cytology and flow cytometry of the CSF led to the final diagnosis of primary leptomeningeal lymphoma (PLML). Clinicians need to be aware that a case of PLML may be misdiagnosed as peudotumor cerebri.

Keywords: Acetazolamide; cerebrospinal fluid cytology; papilloedema; primary leptomeningeallymphoma; pseudotumor cerebri; pseudotumor syndrome; transient visual obscuration.

Axial brain (A, B) and sagittal spine (C) T1-weighted MR images with gadolinium enhancement. (A) There is no parenchymal mass lesion or clear ventriculomegaly in the brain. (B) Mass lesions are not present in the posterior fossa, and the fourth ventricle is not dilated. Leptomeningeal enhancement is seen around the cavernous sinus and roots of the fifth nerve and inner ear on both sides (arrows). (C) Extensive leptomeningeal enhancement of the lumbar and cauda equine can be seen (arrow).
