Acute motor axonal neuropathy (AMAN) is a subtype of Guillain-Barre syndrome and characterized by selective involvement of motor fibers. Acute disseminated encephalomyelitis (ADEM) is a demyelinating disease of central nervous system. The coincidence of central and peripheral nervous system involvement has been reported rarely. We described a 37-year-old male patient presented with fever and altered consciousness. The examination of cerebrospinal fluid and brain magnetic resonance imaging was compatible with acute disseminated encephalomyelitis. Several days after admissionb his mentality was improved but quadriparesis, multiple cranial neuropathies, and areflexia were detected. Electrophysiologic studies suggested axonal form of motor dominant polyneuropathy. We report a case of acute motor axonal neuropathy combined with ADEM. We consider that this case is an example of simultaneous immunologic process to the common pathogenic epitope of central nervous system and peripheral nervous system.

Central nervous system[CNS] involvement of acute lymphoblastic leukemia may occur. However, CNS involvement as a first manifestation of leukemia is very rare. An 8-year-old girl complained of a backache after playing in the water. Neurological examination detected progressing paraparesis. Magnetic resonance imaging[MRI] of the thoracolumbar spine showed a well-circumscribed homogeneous posterior extradural mass lesion extending from T7 to T9. MRI of the brain showed diffused fatty marrow replacement of the calvarium and the skull base. We report a patient with epidural Burkitt's lymphoma of the thoracic and lumbar vertebra causing compression of the spinal cord after pathologic evaluation. The tumor consisted mainly of lymphoblastic cells, which were identical to those originally seen in the bone marrow aspiration and biopsy. After decompressive laminectomy she began consolidation chemotherapy.

As a cause of spinal cord compression, intramedullary spinal tuberculoma with central nervous system (CNS) involvement is rare. Aurthors report a 66-year-old female presented with multiple CNS tuberculomas including spinal intramedullary tuberculoma manifesting paraparesis and urinary dysfunction. We review the clinical menifestation and experiences of previous reported literature.

A 4-year-old female Cocker spaniel was presented with respiratory distress and abdominal distension. Pleural effusion, ascites, hepatosplenomegaly, and superficial lymphadenopathy were observed and multicentric lymphoma was diagnosed by cytological examination. Immunophenotyping of lymph node and bone marrow using polymerase chain reaction for antigen receptor rearrangement identified a stage V lymphoma originating from T-cell. Despite of systemic chemotherapy using L-asparagenase, vincristine, cyclophoaphamide and prednisolone, neurologic deficits came out and progressed. Cerebrospinal fluid analysis revealed neoplastic lymphocytic pleocytosis indicating central nervous system involvement of lymphoma. The postmortem diagnosis was confirmed based on the histology and imunohistochemistry.

Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma. Although progressive lymphadenopathy is a typical feature, extranodal involvement may also occur, including the gastrointestinal tract, skin, bone, thyroid, and testes. Central nervous system invasion is rare, so differentiating it from diseases such as inflammatory demyelinating disorder or infection is essential. DLBCL is therefore a challenge to diagnose, especially when the first findings are neurological symptoms. We report an unusual case of DLBCL that presented as transverse myelitis.

X-linked Charcot Marie Tooth disease type 1 (CMTX1) is a clinically heterogenous X-linked hereditary neuropathy caused by mutation of the gene encoding gap junction beta 1 protein (GJB1). Typical clinical manifestations of CMTX1 are progressive weakness or sensory disturbance due to peripheral neuropathy. However, there have been some CMTX1 cases with accompanying central nervous system (CNS) manifestations. We report the case of a genetically confirmed CMTX1 patient who presented recurrent transient CNS symptoms without any symptom or sign of peripheral nervous system involvement.

The mechanisms of the chronic pain and depression comorbidity have gained significant attention in recent years. The complement system, widely involved in central nervous system diseases and mediating non-specific immune mechanisms in the body, remains incompletely understood in its involvement in the comorbidity mechanisms of chronic pain and depression. This review aims to consolidate the findings from recent studies on the complement system in chronic pain and depression, proposing that it may serve as a promising shared therapeutic target for both conditions. Complement proteins C1q, C3, C5, as well as their cleavage products C3a and C5a, along with the associated receptors C3aR, CR3, and C5aR, are believed to have significant implications in the comorbid mechanism. The primary potential mechanisms encompass the involvement of the complement cascade C1q/C3-CR3 in the activation of microglia and synaptic pruning in the amygdala and hippocampus, the role of complement cascade C3/C3a-C3aR in the interaction between astrocytes and microglia, leading to synaptic pruning, and the C3a-C3aR axis and C5a-C5aR axis to trigger inflammation within the central nervous system. We focus on studies on the role of the complement system in the comorbid mechanisms of chronic pain and depression.

원발성 중추신경계 T 세포 임파종은 모든 뇌종양 중에서 매우 드물게 발생하는 뇌종양이다. 그렇기 때문에 지금까지 보고된 영상의학적인 소견은 매우 드물다. 저자들은 자기공명영상에서 다수의 작은 결절 및 반점형으로 조영증강되는 병변으로 보였던 뇌실질에 발생한 원발성 기타 상세불명의 말초 T 세포 림프종을 경험하였기에 영상의학적인 소견을 중점으로 하여 보고하고자 한다.

Radiation therapy has been widely applied for cancer treatment. Childhood acute lymphocytic leukemia (ALL), characterized by frequent central nervous system involvement, is a well documented disease for the effect of prophylactic cranio-spinal irradiation. Irradiation, however, acts as an oncogenic factor as a delayed effect and it is rare that glioblastoma multiforme develops during the remission period of ALL. We experienced a pediatric radiation-induced GBM patient which developed during the remission period of ALL, who were primarily treated with chemotherapeutic agents and brain radiation therapy for the prevention of central nervous system (CNS) relapse. Additionally, we reviewed the related literature regarding on the effects of brain irradiation in childhood and on the prognosis of radiation induced GBM.

2-Month-old, three related Perro de Presa Canario dogs were evaluated for similar neurological symptoms like circling, head pressing, depressed mental status, hypermetria, and vocalization. On magnetic resonance imaging (MRI) of the brain, there were large, bilaterally symmetrical lesions with involvement of thalamus, and brainstem that were T2- and FLAIR-hyperintense and T1-iso/hypointense. There was no inclusion of cerebellum. Single-voxel spectroscopy acquisition was located in the thalamus where abnormalities were found in MR images. The results of magnetic resonance spectroscopy (MRS) showed markedly decreased N-acetylaspartic acid value. Euthanasia was performed and lesions consistent with the canine spongy degeneration. Alteration in metabolites in the brain can be determined by MRS, which helps in diagnosing degeneration/leukodystrophy of the central nervous system in dogs.
