BACKGROUND: Thymic epithelial tumors (TETs) are uncommon lesions, and cerebral metastases from these tumors are even rarer. We report a case of a posterior fossa metastasis in a patient with a known history of thymic carcinoma. CASE DESCRIPTION: A 47-year-old man with a history of Hodgkin lymphoma and thymic carcinoma presented with headache, nausea, and ataxia. Imaging revealed a large posterior fossa mass. This lesion was completely resected without complications...

Primary dural lymphoma (PDL) is a rare type of primary central nervous system lymphoma (PCNSL); however, its clinical etiology and appearance on magnetic resonance images (MRI) are similar to those of meningioma. We report a case of PDL mimicking a meningioma in the jugular tubercle, with hemiparesis and double vision, and review the published PDL case reports. A 41-year-old woman experienced numbness on her right side, and reported right hemiparesis and double vision 2 days thereafter. Her cranial computed tomography (CT) scan showed a mass lesion in the posterior fossa, and contrasted MRI revealed homogenous tumor with a dural tail sign in the left jugular tubercle...

INTRODUCTION: Primary central nervous lymphoma(PCNSL) is a rare form of non-Hodgkin lymphoma confined to the central nervous system. Most of the lesions are supratentorial and periventricular, often involving deep structures such as corpus callosum and basal ganglion. Isolated intraventricular lymphoma is rare and only a few case reports. We report, to the best of our knowledge, the seventh case of isolated PCNSL in the fourth ventricle in an immunocompetent patient. PRESENTATION OF CASE: A 61-year-old male presenting with 3 months of headache and dizziness followed with unsteady gait for days...

BACKGROUND: The cure rate for childhood intracranial ependymoma is approximately 70% in the setting of a gross total resection followed by radiation, but management remains challenging in patients with residual disease. Therefore, robust biomarkers are needed to guide the development of new targeted therapy. The authors evaluated the expression of several biomarkers in pediatric intracranial ependymoma and observed that the expression of enhancer of zeste homolog 2 (EZH2), a polycomb complex protein involved in epigenetic regulation of gene expression, was independently associated with poor survival...

BACKGROUND: Toxoplasmosis is the most frequent opportunistic infection of the central nervous system among individuals with the acquired immunodeficiency syndrome. Radiographic modalities include brain CT, MRI and PET scan. The differential diagnosis are usually: primary CNS lymphoma, cerebral metastasis, Progressive multifocal leukoencephalopathy, cytomegalovirus. It indicates severe immunodeficiency and, if it remains untreated, it may lead to death. CASE DESCRIPTION: A 65 year old immunodeficiency woman with a Non Hodgkin Lymphoma treated with Chemotherapy...

An 87-year-old man presented with a 1-week history of transient facial numbness, followed by the onset of left diplopia 1 month later. In the neurological examination, he was found to have left abducens nerve palsy. A brain MRI showed an infiltrative lesion invading the left posterior nasal cavity and pterygopalatine fossa, and extending into the left paracavernous region. The histological diagnosis was diffuse large B-cell lymphoma. We report an unusual case of diffuse large B-cell lymphoma occurring in the sinonasal tract with unilateral abducens nerve palsy presenting as an early feature...

Posterior reversible encephalopathy syndrome (PRES) is characterized by reversible vasogenic edema affecting the subcortical white matter of bilateral occipital and parietal lobes. We describe a case of isolated posterior fossa involvement of PRES which occurred during remission induction chemotherapy for T-cell acute lymphoblastic leukemia. Both the brainstem and cerebellum were extensively involved, but the supratentorial structures were completely spared. The follow-up magnetic resonance images revealed reversibility of most lesions...

Primary central nervous lymphoma (PCNSL) is a rare variant of extranodal non-Hodgkin's lymphoma with a especially poor prognosis. The diagnosis is usually encountered in immunodeficient patients but is also encountered, albeit uncommonly, in the immunocompetent. We present a 50-year-old male who developed signs and symptoms of increased intracranial pressure. Imaging revealed the presence of a fourth ventricle mass with obstructive hydrocephalus. First, the patient underwent emergency endoscopic third ventriculostomy followed, few days later, by complete tumor resection via a posterior fossa craniotomy...

Surgical excision in brain metastases has been well evaluated in unique metastases. Two randomized phase III trials have shown that combined with adjuvant whole brain radiotherapy, it significantly improves overall survival. However, even in the presence of multiple brain metastases, surgery may be useful in large, symptomatic or life-threatening lesions (posterior fossa tumor with mass effect). Also, even in lesions amenable to radiosurgery, surgical resection is preferred when tumors displayed cystic or necrotic aspect with important edema or when located in highly eloquent areas or cortico-subcortically...

A 38-year-old woman was diagnosed with cutaneous anaplastic T-cell lymphoma that proved refractory to methotrexate, bexarotene, denileukin diftitox, interferon γ-1b, interferon α-2b, vorinostat, and pralatrexate. She was therefore started on the newly approved monoclonal anti-CD30 antibody brentuximab vedotin. Treatment with brentuximab 1.8 mg/kg IV every 3 weeks quickly led to disappearance of her cutaneous tumors. The day after her second brentuximab infusion she developed word-finding difficulties and unsteady gait...

Bilateral abducens nerve palsy is an unusual clinical presentation, which could be caused by stroke, aneurysm, trauma and malignant neoplasm. We describe here a patient with bilateral abducens nerve palsy caused by large B cell lymphoma originated from clivus. An 83-year-old woman admitted to our hospital because of diplopia and severe posterior neck pain. Her diplopia developed one month before and progressed to her admission. Neurological examination revealed bilateral abducens nerve palsy. Brain MRI with enhancement lesion in the clivus, suggesting that bilateral petroclival segment of the abducens nerves were affected by the lesion...

Atypical teratoid rhabdoid tumor (AT/RT) is a rare entity. In the central nervous system, AT/RT generally arises from the posterior fossa of infants and behaves aggressively. AT/RT is reported to arise from the infratentorial region (63%) and other sites, such as the suprasellar region, cerebellopontine angle, and spinal cord. The pineal region is rare (6%) as a site of origin. Radiation-induced brain tumors are well known. In this report, we present a case of a pineal region tumor causing acute hydrocephalus that could be pathologically diagnosed as AT/RT following prophylactic cranial irradiation for acute lymphoblastic leukemia...

BACKGROUND: Most primary lymphomas of the central nervous system (CNS) are of B-cell origin and are found intra-axially, with a few reported cases of skull base tumors involving the upper clivus or sellar region or both. In this case, a tumor resembling a clivus meningioma without osseous involvement was surgically removed and turned out to be a primary T-cell lymphoma. CASE REPORT: A 60-year-old woman presented with slight right-sided abducens nerve palsy. Cranial imaging revealed an extra-axial mass at the caudal clivus resembling a meningioma...

Granulocytic sarcoma consists of neoplastic granulocytic precursors and myeloblasts. It is a focal lesion seen in 2-10.9% of acute myelogenous leukaemia (AML) patients. It usually develops either concurrently with the AML or after a remission. On rare occasions, it may be an initial manifestation of AML. Most common involvement sites are bone, periostium, soft tissue, lymph nodes and skin. Intracranial granulocytic sarcoma rarely occurs in meningeal or parenchymal form. We present an extremely rare case of intracranial granulocytic sarcoma extending from the posterior fossa to the carotid space via the jugular foramen in a 69 year old female...
