AbstractPrimary malignant lymphoma is an uncommon disease of the central nervous system (CNS). Immunocompromised patients are at high risk of development of malignant lymphoma. We describe a case of primary CNS lymphoma presenting as a solitary cerebellopontine angle lesion. The patient had undergone extirpation of rectal cancer four years previously. Malignant lymphoma presenting as a cerebellopontine angle mass is extremely rare, with only 10 such cases (seven were primary, and the others secondary) previously reported.

AbstractNeurologic disease is commonly encountered in the population infected with human immunodeficiency virus type 1 (HIV-1). Although HIV-1 is responsible for many of these neurologic complications, other organisms will affect the nervous system as the immune deficiency state progresses. With the wide use of potent antiretroviral therapy, the mortality from and incidence of opportunistic infections (OIs) among persons with advanced HIV-1 infection has decreased. Nevertheless, these diseases are still seen frequently, especially among those with limited access to new antiretroviral therapies. Therefore, it remains important to recognize the most common OIs of the central nervous system (CNS) as well as primary CNS lymphoma, which will be the focus of this review.

Abstract Advanced molecular and pathophysiologic characterization of Primary Central Nervous System Lymphoma (PCNSL) has revealed insights into promising targeted therapeutic approaches. Medical imaging plays a fundamental role in PCNSL diagnosis, staging, and response assessment. Institutional imaging variation and inconsistent clinical trial reporting diminishes the reliability and reproducibility of clinical response assessment. In this context, we aimed to: 1) critically review the use of advanced PET and MRI in the setting of PCNSL; 2) provide results from an international survey of clinical sites describing the current practices for routine and advanced imaging, and 3) provide biologically based recommendations from the International PCNSL Collaborative Group (IPCG) on adaptation of standardized imaging practices. The IPCG provides PET and MRI consensus recommendations built upon previous recommendations for standardized brain tumor imaging protocols (BTIP) in primary and metastatic disease. A biologically integrated approach is provided to addresses the unique challenges associated with the imaging assessment of PCNSL. Detailed imaging parameters facilitate the adoption of these recommendations by researchers and clinicians. To enhance clinical feasibility, we have developed both “ideal” and “minimum standard” protocols at 3T and 1.5T MR systems that will facilitate widespread adoption.

A series of 10 patients with a primary non-Hodgkin lymphoma of the central nervous system were observed and treated by the authors. All were diagnosed after a pathologic examination of the surgical material; the lesions were supratentorial in all cases and unifocal in 9. In every case radiation therapy improved clinical conditions and in most cases even radiologic features of the patients. Four patients were alive and without evidence of disease many months after therapy. Four patients died with a relapse in the central nervous system; 3 of them had disseminated disease at the time of death. Two patients died for an unknown cause. Radiation therapy was performed with 60Co source with 2 opposed portals and the whole brain irradiation technique in all cases but 2. Doses ranged from 35 to 54 Gy. The recent literature on this uncommon disease and the most adequate therapeutic possibilities of radiation therapy and chemotherapy, or both, are discussed.

✓Lymphomatous meningitis (LM) due to primary central nervous system (CNS) lymphoma is an uncommon problem in neurooncology and can occur at time of diagnosis or recurrence. Notwithstanding frequent focal signs and symptoms, LM is a disease affecting the entire neuraxis, and therefore staging and treatment need to encompass all cere-brospinal fluid (CSF) compartments. Central nervous system staging of LM includes contrast agent–enhanced cranial computed tomography (CT) or Gd-enhanced magnetic resonance (MR) imaging, Gd-enhanced spinal MR imaging, CT myelography, and radionuclide CSF flow study. Treatment of LM includes involved-field radiotherapy of bulky or symptomatic disease sites and intra-CSF drug therapy. The inclusion of concomitant systemic therapy can benefit patients with LM and can obviate the need for intra-CSF chemotherapy. At present, intra-CSF drug therapy is confined to three chemotherapeutic agents (methotrexate, cytosine arabinoside, and thiotepa) administered by a variety of schedules either by intralumbar or intraventricular drug delivery. Although treatment of LM is palliative and the expected median survival of patients is 4 to 6 months, it often provides stabilization and protection from further neurological deterioration. In patients with primary CNS lymphoma, CNS prophylaxis has been recommended (using a combination of high-dose systemic chemotherapy and intra-CSF chemotherapy), but the strategy remains controversial because high-dose systemic methotrexate is commonly used as an adjuvant therapy. Patients with primary CNS lymphoma at high risk as defined by positive CSF cytology or neuroradiography consistent with LM may benefit from the inclusion of intra-CSF chemotherapy.

ABSTRACT:Background:Flow cytometry of the cerebrospinal fluid (CSF) is used in isolation or as an adjunct to cytology to increase the sensitivity of detecting central nervous system (CNS) lymphoma. We aimed to evaluate the sensitivity of CSF flow cytometry as a diagnostic screening tool for primary CNS lymphoma in patients presenting with undifferentiated neurologic symptoms.Methods:We retrospectively reviewed all CSF samples received by the Calgary Laboratory Services Flow Cytometry Laboratory from 2012 to 2015. Clinical data, laboratory investigations, radiologic imaging studies, and pathological data were analyzed. Clinical review extended to 2 years post-CSF flow cytometric testing.Results:Only 43/763 (5.6%) samples of CSF flow cytometry in 28/573 (4.9%) patients were found to be positive for a hematological malignancy in patients with undifferentiated neurologic symptoms. The overall sensitivity of the test was 13.8% with 25 patients with negative CSF flow cytometry later having a positive biopsy for CNS lymphoma. CSF flow cytometry was negative in all cases when at the time of CSF examination the patient did not have a previous hematological malignancy or findings of abnormal enhancement on MRI (n = 249).Conclusion:CSF flow cytometry has low utility in screening for primary CNS lymphoma in the absence of a previous history of hematologic malignancy or findings of abnormal enhancement on MRI.

Abstract Invasive mold disease (IMD) of the central nervous system (CNS) is a severe infectious complication in immunocompromised patients, but early microbiological diagnosis is difficult. As data on the value of biomarkers in the CNS are scarce, in particular in children, we retrospectively analyzed the performance of galactomannan (GM) and PCR assays in CNS samples of 15 children with proven and probable CNS IMD and of 32 immunocompromised children without fungal infection. Galactomannan in the cerebrospinal fluid (CSF) was assessed in nine of the 15 pediatric patients and was positive in five of them. Polymerase chain reaction (PCR) was performed in eight of the 15 patients and detected nucleic acids from molds in six patients. Galactomannan and PCR in CNS samples were the only positive microbiologic parameter in the CNS in three and two patients, respectively. In four patients, PCR specified the pathogen detected in microscopy. Galactomannan and PCR results remained negative in the CSF of all immunocompromised children without evidence for CNS IMD. Our data suggest that GM and PCR in CNS specimens are valuable additional tools in diagnosing CNS IMD and should be included in the work up of all pediatric patients with suspected mold disease of the CNS.
