Solitary Osteochondroma of the Skull Base: A Case Report and Literature Review
We report a case of an osteochondroma in the posterior clinoid process that occurred in a 43-year-old man with trochlear nerve palsy. Although the potential preoperative diagnoses based on computed tomography and magnetic resonance imaging included other intracranial tumors such as calcified meningioma, thallium-201 single-photon emission computed tomography effectively differentiated osteochondroma from those possibilities. Via an orbitozygomatic approach, a subtotal resection was achieved with a good relief of symptoms. Twenty-two cases of solitary osteochondromas in the skull base have been reported that have demonstrat...

Spontaneous Intracranial Extradural Hematoma in Sickle Cell Disease
We report a clinical case of a 19-year-old young man with sickle cell anemia who presented a sickle cell crisis complicated by the development of multiple acute extradural and subgaleal hematomas that had not been treated surgically. We discuss the physiopathology of this event. Although it is rare, clinicians should be aware of this phenomenon as part of a spectrum of neurologic complications in these patients.[...]Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals:Table of contents  |  Abstract  |  open access Full text (Source: Journal of Neurological Surgery Reports)

Rare Presentation of Giant Cell Tumor in the Internal Auditory Canal: Case Report and Review of the Literature
J Neurol Surg RepDOI: 10.1055/s-0034-1396656Giant cell tumor (GCT) is a benign but locally aggressive bone tumor that usually involves the end of long bones. It is a relatively common neoplasm in patients, constituting 5 to 10% of all benign bone tumors. Approximately 2% of GCTs occur in the craniofacial skeleton with a predilection for the ethmoid, sphenoid, and temporal bones. The skull base location is unique and not commonly described. Hearing loss, headache, tinnitus, and subcutaneous masses are the most commonly reported symptoms in GCTs of the skull base. In this case report we present the first description of a GCT...

A Rare Finding of Schwannoma of the Vidian Canal: A Case Report
Conclusion When a vidian canal tumor is identified, endoscopic endonasal biopsy can be used to confirm the diagnosis before pursuing either surgical or radiotherapy treatment. In particular, fractionated radiation therapy offers a radiobiologically safe means of delivering radiation when there is concern for late radiation-related side effects following treatment completion.[...]Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals:Table of contents  |  Abstract  |  open access Full text (Source: Journal of Neurological Surgery Reports)

Low-Grade Oligodendroglioma of the Pineal Region: Case Report
Conclusion Although the pineal region is a common place for a large number of tumoral lesions, low-grade oligodendrogliomas are extremely rare in this location. This case is only the second account of a benign oligodendroglioma of the pineal region reported in the literature.[...]Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals:Table of contents  |  Abstract  |  open access Full text (Source: Journal of Neurological Surgery Reports)

Concomitant Intraspinal and Retroperitoneal Hemorrhage Caused by an Aneurysm on the Celiac Artery: A Case Report
We present a case in which the diagnosis was complicated by a concomitant intra-abdominal hemorrhage. The patient, taking coumarins, presented with acute back pain and abdominal pain and progressive paresis of the lower limbs. Computed tomography angiography of the abdomen showed an intra-abdominal hemorrhage and an aneurysm of the celiac trunk. MR (magnetic resonance) imaging of the spine revealed a combined subdural and epidural hemorrhage from C1 to L1. Both sites were treated conservatively. After 6 months the patient regained strength in both legs with some persistent loss of strength in the left leg. Follow-up MR ima...

Diffuse Large B-Cell Lymphoma of the Frontal Sinus Presenting as a Pott Puffy Tumor: Case Report
Conclusion Sinonasal NHL is very rare but can occur in the frontal sinus and may present as a suspected Pott puffy tumor.

Role of Evaluating MGMT Status and 1p36 Deletion in Radiosurgery-Induced Anaplastic Ependymoma That Rapidly and Completely Resolved by Temozolomide Alone: Case Report and Review of the Literature
J Neurol Surg RepDOI: 10.1055/s-0034-1396657Stereotactic gamma knife surgery (GKS)-induced brain tumors are extremely rare, and no ependymal tumors induced by GKS have been reported. Therefore, little is known about their clinical, pathologic, and genetic features. In addition, a regimen of adjuvant chemotherapy for anaplastic ependymoma (AE) has not been established. A 77-year-old man presented with a gait disturbance and left-side cerebellar ataxia more than 19 years after GKS performed for a cerebellar arteriovenous malformation. Imaging studies demonstrated an enhancing mass in the irradiated field with signs of intrav...

Pseudo-Cerebrospinal Fluid Rhinorrhea Resulting from Aberrant Cross-Innervation of Trigeminal and Facial Nerves following Skull Base Surgery
Conclusions Pseudo-CSF rhinorrhea exacerbated by mastication has not been previously reported in the literature. We propose aberrant cross-innervation of the trigeminal and facial nerves as the mechanism underlying the patient's condition. Pseudo-CSF rhinorrhea is an important entity to identify following skull base surgery because it may spare patients from the unnecessary invasive procedures and morbidity associated with the management of a presumed CSF leak.[...]Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals:Table of contents  |  Abstract  |  open access Full text (Source: Journal of ...

An Intraventricular Schwannoma with Associated Hydrocephalus and Ventricular Entrapment: A Case Report
J Neurol Surg RepDOI: 10.1055/s-0034-1395493Intraventricular schwannomas are rare primary brain tumors, with fewer than 25 cases reported in the literature. Here, we present the case of a 20-year-old male patient with a 2 year history of blurry vision and dysesthesia involving his right occiput and upper neck. Imaging demonstrated a homogeneously enhancing mass located within the atrium of the right lateral ventricle with associated right lateral ventricular entrapment. Pathology confirmed the tumor to be an intraventricular schwannoma. Imaging findings, presentation, complications, and treatment options for intraventric...

Endoscopic Transnasal Approach for Urgent Decompression of the Craniocervical Junction in Acute Skull Base Osteomyelitis
We present two cases of ventral epidural abscess and osteomyelitis at the craniocervical junction involving C1/C2 that were successfully treated via the endoscopic transnasal approach. Both were treated in staged procedures involving posterior cervical fusion followed by endoscopic transnasal resection of the ventral C1 arch and odontoid process for decompression of the ventral spinal cord and medulla. Dural repairs were successfully performed using multilayered, onlay techniques where required. Both patients tolerated surgery exceedingly well, had brief postoperative hospital stays, and recovered uneventfully to their neu...

“Spontaneous” CSF Fistula due to Transtegmental Brain Herniation in Combination with Signs of Increased Intracranial Pressure and Petrous Bone Hyperpneumatization: An Illustrative Case Report
Conclusion The case illustrates the two main predisposing factors for development of petrous bone CSF fistulas: increased intracranial pressure and thinning of the tegmental roof due to extensive development of air cells. Because the CSF leakage repair does not change the underlying cause, patients have to be informed about the possibility of developing increased intracranial pressure and recurrences of brain herniations at other sites.[...]Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals:Table of contents  |  Abstract  |  open access Full text (Source: Journal of Neurological Surgery Reports)
