The differentiation between glioblastoma multiforme (GBM) and primary cerebral lymphoma (PCL) is important because the treatments are substantially different. The purpose of this article is to describe the MR imaging characteristics of GBM and PCL with emphasis on the quantitative ADC analysis in the tumor necrosis, the most strongly-enhanced tumor area, and the peritumoral edema. This retrospective cohort study collected 104 GBM (WHO grade IV) patients and 22 immune-competent PCL (diffuse large B cell lymphoma) patients...

Primary lymphoma of the CNS (PCNSL) is a diffuse large B cell lymphoma confined to the CNS. To elucidate its peculiar organ tropism, we generated recombinant Abs (recAbs) identical to the BCR of 23 PCNSLs from immunocompetent patients. Although none of the recAbs showed self-reactivity upon testing with common autoantigens, they recognized 1547 proteins present on a large-scale protein microarray, indicating polyreactivity. Interestingly, proteins (GRINL1A, centaurin-α, BAIAP2) recognized by the recAbs are physiologically expressed by CNS neurons...

We describe an atypical man with diffuse large B cell lymphoma localized to the sphenoid wing and adjacent cavernous sinus, initially presenting with isolated ipsilateral facial pain mimicking trigeminal neuralgia due to invasion of Meckel's cave but subsequently progressing to intra-axial extension and having synchronous features of systemic lymphoma. Primary central nervous system lymphoma is uncommon, accounting for approximately 2% of all primary intracranial tumors, but its incidence has been steadily increasing in some groups [1]...

Primary penile lymphoma presenting with priapism as the initial symptom is extremely rare. In total, <10 cases have been previously reported. The diagnosis can be difficult and patients often develop metastasis. The current study reports the case of a 48-year-old male, who presented with a one-month history of painless priapism. On admission to Yantai Yuhuangding Hospital Affiliated to Qingdao University (Yantai, China), examination revealed an erect penis, enlarged lymph nodes in the bilateral inguinal and swelling in the thighs...

We report a case of primary central nervous system lymphoma presenting as multiple intraventricular masses in an immunocompetent 68 year old man with severe headache and unsteady gait. The diagnosis was obtained by analysis of the cerebrospinal fluid and subsequent surgical biopsy. This is an unusual appearance for primary central nervous lymphoma, with the majority of the cases presenting as solitary masses.

Bone involvement is a common finding in many types of lymphomas, particularly in advanced stages. However, cranial vault affliction has been regarded as an exceedingly rare presentation. Here, we report the case of a patient with cranial vault lymphoma who presented with a scalp mass. An 81-year-old woman presented with a gradually growing and non-painful frontal scalp mass that she noticed one month before admission. It was a flatly elevated, round mass measuring about 6×4×4 cm. Computed tomography and magnetic resonance imaging of the brain revealed a contrast-enhancing intracranial extradural mass at the counter-location of the scalp mass...

The diagnosis of primary central nervous system lymphoma (PCNSL) can be suggested by magnetic resonance imaging (MRI). Cerebral PCNSL in immunocompetent patients generally shows marked homogeneous contrast enhancement in MRI. However, confirmation of it requires demonstration of lymphoma cells in stereotactic biopsy of the lesion or in cerebrospinal fluid. In the present case, with radiologic diagnosis of glioma, complete resection of the lesion by micro-neurosurgical technique was performed. The tumor tissue was examined by squash smear, frozen section and paraffin sections...

A 66-year-old man presented with deteriorated bradykinesia, gait disturbance, disorientation, and urinary incontinence for three weeks. Magnetic resonance imaging (MRI) showed dilatation of the ventricles. Cerebrospinal fluid (CSF) examination demonstrated lymphocytic pleocytosis, elevation of protein levels, and decreased of glucose levels. A gadolinium-enhanced MRI revealed lesions in the ventricular wall and choroid plexus, mimicking ventriculitis. No evidence of bacterial, fungal, mycobacterial, or viral infections were observed in the CSF...

We studied the clinicopathological and imaging characteristics of primary central nervous system diffuse large B-cell lymphomas (PCNS-DLBCL). Imaging, pathologic histology, and immunohistochemical staining characteristics were analyzed, and the immunoglobulin heavy and light chain gene rearrangement of 25 PCNS-DLBCL cases was examined. MicroRNA was extracted from 10 cases each of PCNS-DLBCL, extracerebral germinal center DLBCL (GC-DLBCL), and extracerebral non-GC-DLBCL (NGC-DLBCL); we conducted chip hybridization and comparatively analyzed the difference among the three...

We report 2 cases of primary central nervous system (CNS) lymphoma arising in the region of the optic nerve. For both patients, diagnosis of lymphoma was impossible without histological examination because of the rarity of the lymphoma location. The first case involved an 84-year-old woman who developed loss of vision and hypopituitarism. Intraoperative finding was optic glioma; histological diagnosis was diffuse large B cell lymphoma, however. The second case involved a 67-year-old man who developed loss of vision...

PURPOSE: Primary cerebral lymphoma (PCL) and primary intraocular lymphoma (PIOL) belong to the systemic diffuse large B-cell lymphoma family and are characterized by the presence of CD20(+) lymphoma B cells in the brain or the eye. These highly aggressive malignancies have a poor prognosis and no specific therapy. The presence of effector immune cells in the damaged brain and vitreous suggests that treatment with anti-human CD20 (hCD20) monoclonal antibodies might be effective. We developed murine models of PCL and PIOL to assess the intracerebral and intraocular antitumor effect of ublituximab, a promising glycoengineered anti-hCD20 mAb with a high affinity for FcγRIIIa (CD16) receptors...

Spinal primary dural lymphoma (PDL) is uncommon with a total of 37 previous well-documented cases reported, including one diagnosed in the authors' institution. More recently we encountered an additional case of spinal PDL that, similarly to our previous case, was grade 1-2 follicular B-cell PDL. Our two cases were diagnosed over a 3-year interval in a 72-year-old female and a 74-year-old male, respectively. An exhaustive literature review on PDL was performed consequently to reveal that: (i) spinal and cerebral sites of involvement by PDL are constantly mutually exclusive; and (ii) unlike cerebral PDL, which is usually of marginal zone B-cell type, only two of the 38 cases of spinal PDL were diagnosed as such, diffuse large B-cell lymphoma being the most commonly encountered type in the spine...

Lymphomatosis cerebri (LC) is a rare form of primary central nervous system lymphoma characterized by subacute progressive dementia and unsteady gait. MRI study of LC typically reveals diffuse leukoencephalopathy without contrast enhancement. The clinical presentation and MRI features of LC can resemble infectious, inflammatory, toxic or vascular leukoencephalopathy. Hence diagnosis of LC is easily mistaken for other, more common diseases. In this report, we present a case of a 55-year-old man presenting with subacute progressive dementia and ataxic gait...

A 45-year-old man presented with fever, progressive mutism and memory loss, was admitted to our hospital. MR imaging and angiography suggested multiple foci of infarctions and vasculitis without Gadrinium-enhancement. CSF examination revealed pleocytosis with mononuclear cell dominance and elevated protein content. Adenosine deaminase activity was accelerated, and no malignant cell was found. Whole body CT imaging and Garium-scintigraphy were normal. Under the clinical diagnosis of tuberculous meningitis, anti-tubercular drugs with steroid were administered, resulting in marked attenuation of his neurological impairments...

INTRODUCTION: Primary central nervous system vasculitis (PCNSV) is a rare inflammatory arteriopathy confined to the brain, spinal cord, and leptomeninges. Because of its nonspecific presentation and difficulties in making a positive diagnosis, empiric treatment is often instituted. CASE SERIES: We report a case series of 5 patients who were admitted or transferred to the Johns Hopkins Hospital with a clinical history and magnetic resonance imaging findings suggestive of PCNSV...

Primary cranial vault lymphomas (PCVL) are extremely rare tumours. An extensive review of the literature shows that only 26 previous PCVL were reported while only four presented with cortex infiltration. We present a singular case of a 74-year-old woman with a voluminous painful mass lesion of the right temporal scalp. Preoperative neuroradiological assessment showed a lesion involving the scalp, the cranial vault and the subdural space; underneath, a cerebral oedema suggested brain infiltration. The absence of any neurological signs despite brain infiltration makes this case exceptional...
