Abstract OBJECTIVE: We present an unusual dural-based follicular lymphoma with radiological and macroscopic features similar to a meningioma. The unusual location of this tumor and its distinction from meningioma, mucosa-associated lymphoid tissue-type marginal zone B-cell lymphoma of the dura, and intraparenchymal central nervous system lymphoma, dramatically alters the patient's postoperative treatment. The case illustrates the clinical, radiological, and histological relevance of this rare entity. CLINICAL PRESENTATION: A 41-year-old Caucasian man with chronic bifrontal headaches and a raised area over his left frontal cranium that persisted for 1 year presented to the emergency room with nausea and vomiting. His family reported that the patient demonstrated increased irritability and aggressive behavior. A computed tomographic scan revealed a large mass of the left frontal convexity with edema and mass effect. Magnetic resonance imaging scans showed a 5-cm homogeneously enhancing mass in the left posterior frontal lobe. INTERVENTION: Preoperatively, the patient underwent angiography and embolization of the tumor. The patient underwent gross total resection of tumor. The dural-based tumor invaded the cranium and scalp. Neuropathological findings were consistent with low-grade follicular lymphoma. The patient is currently undergoing radiation and chemotherapy. CONCLUSION: The current case represents the first report of extensive intracranial dural involvement by a follicular lymphoma that shows a classic immunophenotype by immunohistochemistry and flow cytometry. The case illustrates the clinical and radiographic similarities between dural-based lymphoma and meningioma. Distinguishing dural-based follicular lymphoma from mucosa-associated lymphoid tissue-type lymphoma and from intraparenchymal primary central nervous system lymphomas, which are more often large cell lymphomas with more aggressive biological behavior, is essential for proper clinical management.

✓ Primary central nervous system lymphoma (PCNSL) is a rare form of primary brain neoplasm, accounting for less than 3% of all primary brain tumors. Ninety percent of cases involve a large B-cell lymphoma that presents as a homogeneously enhancing lesion or lesions, typically deep-seated in the brain parenchyma. The authors describe unusual pathological forms of PCNSLs, including low-grade, T-cell, and Burkitt types, and also rare presentations such as neurolymphomatosis and pituitary lymphomas.

We report a rare case that was initially diagnosed as an inflammatory lesion and ultimately confirmed as primary central nervous system lymphoma (PCNSL) in an immunocompetent patient who was not treated with corticosteroid prior to the initial biopsy. A 70-year-old female patient presented with numbness in the left side of face, arm, and leg. Brain magnetic resonance imaging (MRI) revealed a lesion with intense gadolinium (Gd)-enhancement in the ventral portion of the midbrain. A stereotactic biopsy demonstrated mixed T-cell and B-cell infiltrating inflammatory lesions without demyelination. Three months after postoperative treatment with steroid, the lesion markedly decreased on follow-up MRI. Twenty-six months after the initial attack, she complained of dysarthria and urinary incontinence. Repetitive MRI showed a lesion with homogeneous enhancement, extensively involving the bilateral cerebral hemisphere, corpus callosum, and the right middle cerebellar peduncle. The confirmed diagnosis was diffuse large B-cell lymphoma on the second biopsy. Despite our best efforts, she died 38 months after disease onset. Based on review of the literature and our case, preceding inflammatory lesions are not always demyelinating and T-cell dominant inflammatory lesions. When the initial biopsy reveals an inflammatory lesion in an old-aged patient, the clinician should keep in mind the development of PCNSL and perform close clinical and radiological observations for a timely diagnosis.

Abstract Primary central nervous system lymphoma (PCNSL) is a specific variant of non-Hodgkin's lymphoma confined to the brain, leptomeninges, spinal cord, and/or eyes. The majority of PCNSL is diffuse large B-cell lymphoma (DLBCL), however, a small percentage are categorized as low-grade lymphomas (LGL). Compared to high-grade and aggressive DLBCL, LGL are indolent; allowing for targeted and less neurotoxic first-line treatments. There is currently no consensus for LGL treatment. A patient at our institution was diagnosed with LGL without extra-CNS involvement 11/2018 and then, successfully treated with rituximab monotherapy. This 65 year-old, immunocompetent woman presented with one month of right leg weakness and numbness. Brain MRI demonstrated a subtly enhancing infiltrative left thalamic lesion extending into the left frontal lobe with surrounding edema. Flow cytometry on spinal fluid showed rare monotypic B-cells. Brain biopsy results showed an atypical predominantly perivascular lymphoid infiltrate. These atypical small lymphoid cells had mature-appearing nuclear chromatin, absent nucleoli, and uniformly expressed CD79a and CD20 with variable PAX-5 expression, lacked CD56 and CD117 expression, and had plasmacytic differentiation; thus consistent with marginal zone lymphoma, a type of indolent B-cell lymphoma. There was no evidence of extra-CNS involvement on PET scan, bone marrow biopsy, or ocular exam. She had normal cognitive functioning on neuropsychological testing. Interestingly, SPEP showed a monoclonal IgM immunoglobulin of kappa-light chain-type that became a monoclonal protein in the gamma fraction. Additionally, CT abdomen initially showed splenomegaly that resolved on repeat imaging a year later. Radiation therapy was deferred due to high risk. Weekly rituximab 500mg/m2 was initiated for 4 doses, then monthly for 4 doses. Therapy was well tolerated and she noted clinical improvement plus there was positive response on brain imaging. Repeat ophthalmology exam and CT body without any evidence of cancer. She is now 29 months progression-free since completing rituximab.

Primary Central Nervous System Lymphoma (PCNSL) is a rare invasive extranodal non- Hodgkin lymphoma, a vast majority of which is Diffuse Large B-Cell Lymphoma (DLBCL). Although high-dose methotrexate-based immunochemotherapy achieves a high remission rate, the risk of relapse and related death remains a crucial obstruction to long-term survival. Novel agents for the treatment of lymphatic malignancies have significantly broadened the horizons of therapeutic options for PCNSL. The PI3K/AKT/mTOR signaling pathway is one of the most important pathways for Bcell malignancy growth and survival. Novel therapies that target key components of this pathway have shown antitumor effects in many B-cell malignancies, including DLBCL. This review will discuss the aberrant status of the PI3K/AKT/mTOR signaling pathways in PCNSL and the application prospects of inhibitors in hopes of providing alternative clinical therapeutic strategies and improving prognosis.

Abstract Background Secondary central nervous system lymphoma (SCNSL) is defined as lymphoma involvement within the central nervous system (CNS) that originated elsewhere, or a CNS relapse of systemic lymphoma. Prognosis of SCNSL is poor and the most appropriate treatment is still undetermined. Methods We conducted a retrospective study to assess the feasibility of an R-MIADD (rituximab, high-dose methotrexate, ifosfamide, cytarabine, liposomal formulation of doxorubicin, and dexamethasone) regimen for SCNSL patients. Results Nineteen patients with newly diagnosed CNS lesions were selected, with a median age of 58 (range 20 to 72) years. Out of 19 patients, 11 (57.9%) achieved complete remission (CR) and 2 (10.5%) achieved partial remission (PR); the overall response rate was 68.4%. The median progression-free survival after CNS involvement was 28.0 months (95% confidence interval 11.0–44.9), and the median overall survival after CNS involvement was 34.5 months. Treatment-related death occurred in one patient (5.3%). Conclusions These single-centered data underscore the feasibility of an R-MIADD regimen as the induction therapy of SCNSL, further investigation is warranted.

Primary central nervous system lymphoma (PCNSL) is an uncommon variant of extra-nodal non-Hodgkin’s lymphoma. Three regions can be involved in PCNSL: the brain, the spine, or the vitreus and retina. Spinal PCNSL is rare. It can mimic neoplasm, infection, and inflammation. Diagnostic confirmation is by tissue biopsy, and even then, tissue corroboration may be altered by an inflammatory overlay. We report a 59-year-old woman who we saw after she had 4 weeks of ascending tetraparesis plus bowel and bladder incontinence. Upon presentation, the patient was ventilator-dependent and locked-in. She reported normal sensation through eye-blinking. Magnetic resonance imaging (MRI) brain revealed signal intensity in the bilateral corona radiata and restricted diffusion in the right thalamus, whereas, MRI cervical, and thoracic spine showed T2 prolongation in the anterior medulla and upper cervical cord, with enhancement to C2-C3, and long segment hyperintensity from T1-T9 levels, respectively, suggestive of neuromyelitis optica spectrum disorder. Cerebrospinal fluid cytomorphology and flow cytometry were inconclusive for lymphoma/leukemia, but oligoclonal bands were present. Serum aquaporin-4 (AQP-4) antibodies were negative. MR spectroscopy demonstrated NAA reduction, mild lipid lactate peak, and relative reduction of choline on the side of the lesion, favoring demyelination. She received 5-days of intravenous methylprednisolone, followed by 7 sessions of plasma exchange without clinical improvement. Stereotactic biopsy of the right thalamic lesion revealed diffuse large B-cell lymphoma. PCNSL can mimic a demyelinating process early on, as steroid treatment could disrupt B-cell lymphoma cells, thus masking the correct diagnosis.
