Background. Spinal sarcoidosis is a rare subgroup of neurosarcoidosis. Although most sarcoid lesions develop in the intramedullary compartment, intradural extramedullary (IDEM) spinal sarcoidosis is an extremely rare entity. Case Presentation. We herein report a case of IDEM spinal sarcoidosis mimicking a meningioma. A 32-year-old man presented to the hospital with clumsy hands and was unable to walk without assistance. Magnetic resonance imaging (MRI) of the cervical spine revealed a dural tail sign that is common in meningiomas. The patient underwent gross total resection. The pathological findings consisted with a sarcoid leision of the spinal cord. The patient’s myelopathy recovered after surgery. Conclusions. Physicians should be alert for the possibility of IDEM sarcoidosis mimicking a meningioma in the differential diagnosis of IDEM spinal cord tumors.

Pilocytic astrocytomas and meningiomas are benign, primary brain tumors that may involve the optic tract. Classically, the presence of a dural “tail” sign may differentiate a meningioma from other intracranial lesions. In this report, we describe a mass with the typical appearance of a clinoidal meningioma on magnetic resonance imaging (MRI) but postoperatively diagnosed as a pilocytic astrocytoma. This case illustrates the rare occurrence of a pilocytic astrocytoma mimicking a meningioma on MRI.

Spinal cord ischemia most often presents as an anterior spinal artery syndrome and involves watershed regions of the spinal cord. The clinical presentation and etiologies can be heterogeneous, but cord infarcts are typically the result of aortic surgeries, systemic hypotension, vertebral artery and aortic dissections, embolus, or vascular malformations. Given that it is a rare entity, involving symptoms that can progress over minutes to hours, a diagnosis is often delayed until after conventional windows for revascularization, including thrombolysis, have passed. Magnetic resonance imaging (MRI) is usually required to confirm the diagnosis.

Abstract Background Meningiomas typically manifest on magnetic resonance imaging (MRI) as iso- to hypointense on T1-weighted imaging and iso- to hyperintense on T2-weighted imaging. After contrast administration, they usually homogeneously enhance and exhibit a visible dural tail. Meningiomas with atypical findings may be misdiagnosed. Case presentation We report a 50-year-old female patient with a pathologically diagnosed fibrous meningioma (World Health Organization grade I) that exhibited ring enhancement on MRI. Conclusions Meningiomas may rarely present with ring enhancement on MRI. The natural history and mechanisms of cystic degeneration and enhancement in the various types of meningioma require further study.

Introduction. Spinal mobile tumors are very rare. We herein report a case of paraplegia caused by migration and incarceration of thoracic mobile schwannoma after myelography. Case Presentation. A 25-year-old man who had weakness and numbness in both his legs also had pain radiating to the back that was induced by back flexion or extension and jumping. Magnetic resonance imaging (MRI) showed an intradural extramedullary lesion at the T10 and T11 levels. Myelography was performed but discontinued due to his back and lower limb pain. Computed tomography after myelography revealed a rostrally migrated intradural mass with a discrepancy in the exact location in comparison to the MRI findings. He underwent a second lumbar puncture and drained the cerebrospinal fluid (CSF) to aid the spinal cord, because the symptoms gradually worsened and led to paraplegia. After the drainage of the CSF, his symptoms were immediately resolved. The day after myelography, he underwent complete resection of the tumor with the diagnosis of schwannoma. One year after the surgery, he had been working despite having hyperreflexia in his lower limbs with no weakness or sensory disturbance. Conclusion. Severe neurological deficits associated with spinal cord damage can occur due to migration of mobile tumors.

Subependymomas can rarely occur in the spinal cord, and account for about 2% of symptomatic spinal cord tumors. It most often occurs in the cervical spinal cord, followed by cervicothoracic junction, thoracic cord and conus medullaris. It often has an eccentric location in the spinal cord and lacks gadolinium enhancement on magnetic resonance imaging. We present a rare case of symptomatic subependymoma of the cervical spinal cord, which underwent successful gross total resection. Surgical pearls and nuances are discussed to help surgeons to avoid potential complications.The video can be found here: http://youtu.be/Rsm9KxZX7Yo.

AbstractWe describe a case of an intradural extramedullary inflammatory myofibroblastic tumor of the cervical spine. A 56-year-old woman presented with progressive neck pain, radiating to the right scapula, without any neurologic deficit. Magnetic resonance imaging showed an intradural extramedullary tumor with a dural tail sign, located at the C3–T1 segment with homogeneous contrast enhancement. The patient was operated on for a suspected meningioma. Pathologic examination showed fibrosis and inflammation with infiltration of B and T lymphocytes accompanied by plasmocytes, macrophages, and myofibroblast oocytes. We present the clinical course and review of the literature.

Background: Primary spinal cord tumors are rare neoplasms that lead to significant morbidities. They representing about 2–4% of all tumors that affect the central nervous system. According to their relation to the dura, and spinal cord they are classified into extradural, intradural extramedullary and intradural intramedullary tumors. Magnetic resonance imaging is the radiological investigation of choice for the diagnosis of intradural tumors both intra and extramedullary. Surgical excision is the best treatment modality in the majority of patients. Patients and Methods: This is a retrospective study of thirty patients, fifteen males, and fifteen females suffering spinal cord tumors. Median age at diagnosis 41years. Follow up period range from 6months to 43 months with average 24 months. Neurological assessment of the patients carried out by ASIA (American spinal injury association) scoring. Radiological evaluation occurs through MRI (magnetic resonance imaging) with contrast. Of the studied group seven cases were intradural intramedullary and twenty-three cases were intradural extramedullary. The utilized surgical approach was modified Sheehan technique and all the cases were operated by a single surgeon to avoid the inter surgeon variability. Histopathological assessment was done for the excised specimen for all patients. Results: Thoracic region most affected 53.3%, followed by cervical 23.4%, then lumbar (20%) regions. 76.7% intradural extramedullary, and 23.3% intradural intramedullary. Schwannoma 43.3% and Meningioma (20%) were the most pathology. ASIA group C decreased from 40% to 6.7%, and ASIA group D decreased from 60% to 26.7%, and we got a new ASIA group E 66.7% didn’t exist before surgery. Conclusion: The utilized surgical technique is very effective and safe as we get wide corridor for tumor excision, so increasing the effectiveness of operative microscopy and other operative tools, and improve the surgical outcome as noticed in postoperative neurological status.

AbstractGlioblastoma multiforme (GBM) is the most frequent and most aggressive primary brain tumor in adults, mainly located in the cerebral hemispheres. In the literature, few cases of primary GBM have been reported to have radiographic and intraoperative features of extra-axial lesions, leading to a diagnostic dilemma. Despite the advances in imaging modalities, the diagnosis of GBM can be challenging, and it is mainly based on the histopathologic confirmation of the excised tumor. We describe the case of a 76-year-old previously healthy female patient who presented to our hospital due to speech disturbances and cognitive impairment. The diagnosis of the tumor type on magnetic resonance imaging (MRI) was difficult, as the findings were suggestive of a malignant meningioma due to the heterogeneous enhancement of a dural-based mass with a dural tail sign. Moreover, the intraoperative findings revealed an extra-axial mass attached to the dura. A histological examination confirmed the diagnosis of glioblastoma with arachnoid infiltration. The patient underwent adjuvant radiotherapy and concomitant temozolomide treatment, she had clinical improvement postoperatively, and was stable during the six months of follow-up. Glioblastoma should be considered in the differential diagnosis of primary extra-axial mass with atypical and malignant features, especially in elderly patients.

Abstract Background Mature presacral (retrorectal) teratoma is very rare. We report a case in which a mature retrorectal teratoma in an adult was successfully treated with laparoscopic surgery. Case presentation A 44-year-old woman was diagnosed with a presacral tumor during a physical examination. Endoscopic ultrasonography (EUS) revealed a multilocular cystic lesion; the lesion was on the left side of the posterior rectum and measured approximately 30 mm in diameter on both contrast-enhanced pelvic computed tomography (CT) and magnetic resonance imaging (MRI). The presumptive diagnosis was tailgut cyst. However, the histopathological diagnosis after laparoscopic resection was mature teratoma. It is still difficult to preoperatively diagnose mature retrorectal teratomas. Conclusions Laparoscopic resection of mature retrorectal teratomas is a feasible and promising method that is less invasive and can be adapted without extending the skin incision.
