Silent Corticotroph and Somatotroph Double Pituitary Adenoma: A Case Report and Review of Literature
In this report, we present the case of a 28-year-old man with a 1-year history of recurrent headaches. Imaging revealed a 2.1 (anterior-posterior) × 2.2 (transverse) × 1.3 (craniocaudal) cm pituitary adenoma invading into the left cavernous sinus and encasing the left internal carotid artery. Endoscopic transnasal resection was performed without complications. Immunohistochemical staining revealed a double adenoma consisting of distinct sparsely granulated somatotroph and densely granulated corticotroph cells that were positive for growth hormone and adrenocorticotropic hormone, respectively. Ki-67 index labeling...

Intraosseous Lipoma of the Calvaria in the Early Stage Resembling Normal Fatty Marrow
J Neurol Surg Rep 2022; 83: e29-e32 DOI: 10.1055/s-0042-1747972Intraosseous lipoma (IOL) is a benign bone tumor that usually arises from the lower limb and rarely arises from the skull. Radiological diagnosis of a typical case is not problematic due to its characteristic calcification and marginal sclerosis. Here, we report a case of calvarial IOL in the early stage lacking conventional radiopathological features. The patient is a 7-year-old girl who presented with a slow-growing protuberance on the vertex of the head. Computed tomography displayed a low-density mass without calcification that was continuous with the surro...

Spontaneous Spinal Subdural Hematoma Secondary to Hemophilia A and Zanubrutinib
J Neurol Surg Rep 2022; 83: e19-e22 DOI: 10.1055/a-1759-9841Spontaneous spinal subdural hematomas (SSH) are rare occurrences that can occur most commonly secondary to vascular malformations or coagulopathies. Only a small fraction of spontaneous SSHs are caused by acquired coagulation disorders such as leukemia, hemophilia, and thrombocytopenia. This case report describes a patient with a history of Guillain–Barré syndrome (GBS), hemophilia A, and mantle cell lymphoma, on zanubrutinib therapy, a Bruton tyrosine kinase inhibitor associated with a risk of spontaneous hemorrhage. This patient developed a spontaneous spinal...

Holohemispheric Prostate Carcinoma Dural Metastasis Mimicking Subdural Hematoma: Case Report and Review of the Literature
We present a case of prostate carcinoma metastatic to the dura that was initially thought to be a large isodense subdural hematoma and was treated with surgical decompression. We also review the literature regarding prostate dural metastases mimicking subdural hematomas and discuss the relevant imaging findings, treatments, and outcomes. Dural metastasis should be considered when a patient with known metastatic prostate cancer presents with imaging evidence of a subdural mass.

Squamous Cell Carcinoma of the Temporal Bone Arising from Cholesteatoma: A Case Report and Review of the Literature
Conclusion SCCTB may arise from cholesteatoma. A high index of suspicion for SCCTB should be maintained in patients with a prior history of cholesteatoma and evidence of a temporal bone mass with persistent otologic symptoms.

Rupture of the Superior Sagittal Sinus in Penetrating Head Injury —Management of a Rare Trauma Mechanism
We report on a patient who in suicidal intent inflicted on himself a penetrating brain injury near the vertex with a captive bolt gun. A laceration at the junction of the middle to the posterior third of the superior sinus occurred by bolt and bone fragments leading to critical stenosis and subsequent thrombosis. Upon surgery, the proximal and distal sinus openings were completely thrombosed. The sinus laceration was closed by suture and the intraparenchymal bone fragments were retrieved. Postoperative angiography disclosed persistent occlusion of the superior sagittal sinus. The patient did not develop any symptoms due to...

Rapidly Progressive Pituitary Apoplexy in a Patient with COVID-19 Disease Treated with Endoscopic Endonasal Surgery
This report describes a case of pituitary apoplexy with rapidly evolving hemorrhage in a 74-year-old female with coronavirus disease 2019 (COVID-19) disease. The patient presented with severe headache and mild respiratory symptoms, with laboratories concerning for pituitary hypofunction. Brain imaging demonstrated a sellar mass concerning for a pituitary adenoma with ischemic apoplexy. She subsequently developed visual deficits within 24?hours of presentation, and repeat imaging demonstrated evolving hemorrhage and new mass effect on the optic chiasm. She was successfully managed with urgent endoscopic endonasal surgery de...

Evolution in Sinonasal Mucosal Melanoma Management
J Neurol Surg Rep 2022; 83: e1-e2 DOI: 10.1055/s-0041-1741380Sinonasal mucosal melanoma is a rare and aggressive cancer with poor prognosis. Surgical resection with clear margins, when possible, remains the treatment of choice. Radiation therapy is generally used in the adjuvant setting with improved rates of local control following complete resection. Traditional chemotherapeutic agents do not improve the rates of locoregional control or survival. Immunotherapy has been used with some responders but with overall relatively poor outcomes. These outcomes highlight the need for new agents and more prospective trials in this ...

Carotid Artery-Cavernous Segment Injury during an Endoscopic Endonasal Surgery: A Case Report and Literature Review of the Overlooked Option for Surgical Trapping in the Hyperacute Phase
J Neurol Surg Rep 2021; 82: e53-e62 DOI: 10.1055/s-0041-1740511Internal carotid artery (ICA) injury is a catastrophic complication of endoscopic endonasal surgery (EES). However, its standard management, emergent endovascular treatment, may not always be available, and the transnasal approach may be insufficient to achieve hemostasis.A 44-year-old woman with pituitary adenoma underwent EES complicated with the ICA cavernous segment injury (CSI). In urgent intraoperative angiogram, a good collateral flow from the contralateral carotid circulation was observed. Due to the unavailability of intraoperative embolization, emerge...

Targeted Epidural Blood Patch Treatment for Refractory Spontaneous Intracranial Hypotension: A Case Report
We reported a patient who was treated with epidural blood patch (EBP) five times for refractory SIH and SDH surgery. Recent Findings We experienced that targeted EBP was useful in refractory SIH, and also can be performed safely prior to drainage of the hematoma. Summary We report the case of SIH patient with a bilateral SDH who came to our hospital and was discharged 2 weeks later with no neurologic deficit after trephination and five times EBP treatment. It shows that targeted EBP was useful in refractory SIH, and also can be performed safely prior to drainage of the hematoma. [...] Georg Thieme Verlag KG R...

Combined Pipeline Embolization Device with Endoscopic Endonasal Fascia Lata/Muscle Graft Repair as a Salvage Technique for Treatment of Iatrogenic Carotid Artery Pseudoaneurysm
We describe the use of a combined Pipeline embolization device (PED) with endoscopic endonasal repair using a fascia lata/muscle graft to treat an iatrogenic ICA pseudoaneurysm and report long-term radiographic follow-up. Further investigation into the utility of directed endoscopic endonasal repair of iatrogenic pseudoaneurysms initially treated with PED is necessary, especially given the need of post-PED anticoagulation and the rate of permanent neurological deficit after ICA sacrifice.

Regression of Multiple Meningiomas after Discontinuation of Chronic Hormone Therapy: A Case Report
Conclusion A history of chronic hormone therapy should be included when evaluating patients diagnosed with meningiomas, particularly at a younger age and with multiple meningiomas. Cessation of exogenous progesterone resulting in regression of meningiomas suggests a direct action of progesterone on growth. Future studies are warranted to better elucidate this relationship.

Induction Chemotherapy for Orbit Preservation in Sinonasal Squamous Cell Carcinoma
J Neurol Surg Rep 2021; 82: e36-e37 DOI: 10.1055/s-0041-1736160Sinonasal squamous cell carcinoma (SNSCC) is a rare and aggressive malignancy which often presents at an advanced stage. The gold-standard treatment includes negative-margin surgical resection plus adjuvant therapy. In cases of orbital invasion, surgery requires orbital exenteration which can carry significant morbidity and result in decreased quality of life. In selected patients, induction chemotherapy (IC) can allow for orbit preservation without compromising oncologic outcomes. The available literature will be briefly discussed.
