case 1
Case 1

58 yo female with decreased vision OD

Diagnosed with bilateral granulomatous pan-uveitis

1/2013 presented with dizziness, vision changes & ear discharge

case 1 continuation
Case 1 Continuation

Had a brain biopsy & started treatment

Patient develop left eye blindness 2 days after brain surgery

Vitreous fluid cytometry: Large B cell lymphoma


3 of 55 patients during an 11- year period had primary vitreous involvement without systemic symptoms

5% of patients with systemic lymphoma had vitreous involvement


1ry vitreoretinal lymphoma

  • 1ry vitreoretinal lymphoma (PVRL) is a subset of primary CNS lymphoma (PCNSL).
  • PVRL presents in the eye with or without simultaneous CNS involvement.
  • An extranodal non-Hodgkin, diffuse large B-cell lymphoma.
  • Median age of onset is late 50s and 60s with a female preponderance.
  • 25% of patients with PCNSL without eye involvement subsequently develop PVRL.
  • 60–80% with PVRL without CNS involvement subsequently develop PCNSL.
  • Median survival after CNS involvement is reported to be 12–18 months.

case 22
Case 2

Lumbosacral hemilaminotomy, dural biopsy, intradural exploration & filumterminale biopsy

Diagnosis: Diffuse leptomeningeal oligodendroglioma


Disseminated leptomeningealoligodendroglioma

  • Diffuse leptomeningealgliomatosis is a rare condition in which gliomagrows primarily within the subarachnoid space rather than within the brain parenchyma.
  • While the majority of these diffuse leptomeningealgliomasare astrocytic, several cases of diffuse leptomeningealoligodendroglioma have been reported, including primary cases where no intraparenchymal lesions were identified.
  • Many of the cases of diffuse leptomeningealoligodendroglioma have occurred in children.
  • Diagnosis can be difficult, since CSF generally shows elevated protein levels without neoplastic cells, and only fibrosis may be evident in the biopsy .
  • Histology often demonstrates round, oligodendroglioma-like cells with perinuclearhalos.
  • While these tumors are often low-grade, anaplastic progression can occur and is associated with a shorter survival time.
  • In a series of 9 patients who died from this disease, survival ranged from 3 months to 21 yrs.
