Epstein-Barr virus hemorrhagic meningoencephalitis: case report and review of the literature

Neurologic complications related to Epstein-Barr virus (EBV) in immunocompetent adults are rare and most commonly self-limited. However, severe cases have been previously reported in the literature. We describe a case of meningoencephalitis with frontal bilateral hemorrhage in a non-immunocompromised adult following an EBV infection of the central nervous system confirmed by the presence of EBV-DNA in the cerebrospinal fluid. During the patient’s hospital stay, there was a favorable clinical and radiologic evolution and the patient was discharged asymptomatic. To our knowledge, this is the fourth case of hemorrhagic meningoencephalitis related to EBV and the first one in an immunocompetent patient with a favorable outcome.

血栓性血小板减少性紫癜(thrombotic thrombocytopenic purpura,TIP)是一种少见的血液系统疾病.虽然该病的发病率相对较低,但多数患者起病急骤,病情凶险,如不能正确诊断并及时有效治疗,病死率极高.部分以神经系统症状首发或主要表现的患者,容易被误诊为脑炎或脑血管病而延误治疗.     

Rosai-Dorfman disease presenting as cervical extradural lesion: a case report with review of literature

Sinus histiocytosis with massive lymphadenopathy or Rosai-Dorfman disease is a rare, but well documented entity. We report a lady who presented with progressive quadriparesis, with cervical extradural lesion on magnetic resonance imaging. She underwent decompression of the lesion and histological diagnosis of the lesion was Rosai-Dorfman disease. On one-year follow-up, she had complete improvement of the deficits with no further progression of the lesion. The presentation of this disease as an isolated spinal extradural mass lesion is quite rare, with only six cases reported in literature.     

Sixth nerve schwannoma: a case report with literature review

A 40-year-old woman presented with diplopia and left VI nerve palsy. After investigations, diagnosis of a meningioma in the parasellar-prepontine region was considered. Following angiography and embolization, near-total excision of the tumour attached to abducens nerve was performed. Histological examination was consistent with the diagnosis of schwannoma. This is the thirteenth case report of a schwannoma of cranial nerve VI and the first such case where embolization of feeding tumour vessels was performed.

Primary spinal melanoma of the cervical leptomeninges: report of a case with brief review of literature

Central nervous system primary malignant melanoma accounts for approximately 1% of all melanomas. Primary spinal melanomas are even more unusual. We report a patient with primary spinal melanoma of the cervical leptomeninges. The histology of the tumor showed tumor cells arranged in sheets, ill-defined fascicles and nests and displayed a moderate grade of cellular and nuclear pleomorphism and mitoses with abundant pigment in the cytoplasm. The tumor cells were immunoreactive for HMB-45, and for S-100.

Neonatal anterior cervical arachnoid cyst: case report and review of the literature

OBJECTIVE: Anterior cervical arachnoid cysts are rare in the pediatric population, with only 16 cases reported. We present the first case of an anterior cervical arachnoid cyst in a neonate and review the literature on pediatric cervical arachnoid cysts. CLINICAL PRESENTATION: A 16-day-old baby girl with a history of myelomeningocele repair progressively developed symptoms of upper extremity weakness over the course of 2 weeks. Magnetic resonance imaging (MRI) demonstrated a compressive arachnoid cyst extending from C2 to C7. INTERVENTION: The child was taken for posterior cervical laminoplasty and cyst fenestration. Intraoperatively, diffuse cervical arachnoiditis was noted. Rapid improvement in upper extremity paresis was noted within 24 h of surgery, and MRI confirmed decompression of the cyst. However, flaccid upper extremity paresis recurred within 2 weeks. MRI confirmed recurrence of the anterior cervical arachnoid cyst. The child was taken for a secondary fenestration and stenting of the cyst. Only partial improvement in arm function was noted by 1 month following reoperation. CONCLUSION: Arachnoid cysts can be effectively treated with surgical fenestration, shunting, and complete or partial excision. Rapid identification and treatment results in improvement in myelopathic symptoms; however, the most efficacious treatment modality remains unknown. Of the 17 cases of anterior cervical arachnoid cysts reported in the literature, 11 (65%) have had either prior myelomeningocele repair or a history of spinal trauma. Anterior cervical arachnoid cysts should be considered in the differential diagnosis of acute onset myelopathy in the pediatric population especially in cases with a history of spinal trauma or myelomeningocele repair.
