The objective of this study is to present a rare case of an invaginated inferior vena cava (IVC) aneurysm in the lumbar intradiscal space. A 73-year-old woman with lower back pain and bilateral lower extremity swelling presented to the clinic. She had undergone spinal surgery performed thrice at the same site (L4-L5) in another hospital and a separate posterolateral fusion surgery procedure 3 years previously. On plain radiography, pseudarthrosis was observed at L4-L5 segment. Contrast computed tomography (CT) imaging revealed a dilatation of the IVC in the intradiscal space of L4-L5...

Dermoid tumors originating from the cavernous sinus are typically intradural, and thus, presentation with ophthalmoplegia is uncommon. Infantile dermoid tumors originating from the interdural space of the lateral wall of the cavernous sinus are also very rare. We herein present a 4-year-old infantile case of a dermoid cyst that was embedded in the lateral wall of the cavernous sinus. The patient presented with oculomotor nerve palsy. Magnetic resonance image demonstrated a well-circumscribed oval lesion inside the lateral wall of the left cavernous sinus...

Concurrent multiple tumors developing in the spinal cord are rare, except for in genetic disorders, such as neurofibromatosis and von Hippel-Lindau disease. Furthermore, concurrent tumors arising in the same spinal level with discrete histopathology are much rarer. We report two such cases. Case 1: A 53-year-old man presented with intracranial hemorrhage that manifested as disturbed consciousness and right hemiparesis. Magnetic resonance (MR) angiography demonstrated severe stenosis of the terminal portion of the bilateral internal carotid arteries, implying Moyamoya disease...

We report a case of a young male who received multiple surgical treatments for repeated recurrence of skull base mesenchymal chondrosarcoma (MC). When the patient was 18 years old, we subtotally removed the skull base MC and he was treated with stereotactic radiosurgery for remnant tumors in the left cavernous sinus. After 30 months, we removed residual tumors that had regrown partially, via combined endonasal endoscopic and orbitozygomatic approaches. Over the next 65 months, the patient refused radical resection, and received six salvage surgeries, two stereotactic radiotherapies, and five stereotactic radiosurgeries for repeated recurrence...

The surgical removal of giant solid hemangioblastoma involves a high risk of perioperative bleeding and requires attentive hemostasis. Here, we present a case of a giant solid hemangioblastoma accompanied with hemophilia which was previously undiagnosed. A 35-year-old man without any past medical history was admitted with diplopia and ocular motility disorder. computed tomography (CT) and magnetic resonance imaging (MRI) revealed obstructive hydrocephalus and a solid giant tumor of more than 4.0 cm in diameter in the right cerebellopontine angle (CPA)...

The occurrence of cerebral vasospasm secondary to bacterial meningitis is relatively rare. Furthermore, there is no specific treatment cerebral vasospasm. Endovascular treatment may be essential for cases with the advanced clinical course. Balloon angioplasty or intra-arterial injection of verapamil, nicardipine, or nitroglycerin has been previously reported. We experienced successful treatment using intra-arterial infusion of fasudil hydrochloride. To our knowledge, this is the first case to report the intra-arterial injection of fasudil hydrochloride for treating cerebral vasospasm secondary to bacterial meningitis...

We report a case of an encapsulated subdural hematoma in the posterior cranial fossa, showing spontaneous development and rapid increase in size after cardiac surgery. An 86-year-old woman underwent aortic valve replacement for aortic valve stenosis, followed by anticoagulant therapy with heparin. Three days after the cardiac surgery, she complained of headache. Computed tomography revealed development of a subdural hematoma in the posterior cranial fossa. The hematoma rapidly increased in size within 7 days...

We report the case of a patient with a spinal extradural arteriovenous fistula (AVF) associated with Cowden syndrome (CS) that was successfully treated by endovascular surgery. CS is an autosomal dominant disorder associated with diverse symptoms caused by a deleterious mutation in the phosphatase and tensin homolog ( PTEN ) gene. A 67-year-old woman was diagnosed with CS based on her medical history of multiple cancers for which she underwent abdominal surgery, macrocephaly, Lhermitte-Duclos disease, and facial papules...

The authors reported a rare case of young women with neurofibromatosis type I (NF-I) who were successfully treated from the traumatic dislocation of a thoracic vertebra caused by a simple fall, and the relevant literature was reviewed. Due to various spinal dystrophic changes, the conventional posterior spinal fusion surgery was modified for the treatment. Spinal deformity is a common feature of NF-1, and a dystrophic lesion, like dural ectasia, provokes weakness in spinal structural. Unexpectedly, only seven similar cases were found...

Tentorial meningiomas, not involving the cerebellopontine angle cistern or cranial nerves, rarely cause symptoms of cranial nerve disturbance. We report a case of a patient with a paramedian tentorial meningioma who presented with hearing loss as a result of indirect compression of the vestibulocochlear nerve by the herniated cerebellar flocculus into the internal acoustic meatus. A 50-year-old woman had presented with hearing loss in her right ear. Magnetic resonance imaging (MRI) revealed a large tentorial meningioma in the right posterior cranial fossa...

Olfactory neuroblastoma is an uncommon malignant tumor of neural crest origin arising from the olfactory epithelium of the superior nasal cavity. There are some reports of local recurrence or continuous extension along the olfactory epithelium to the central nervous system, but non-contiguous distant meningeal metastasis without local recurrence at the primary site is rare. We report a case of non-contiguous meningeal recurrence of olfactory neuroblastoma presenting as a giant frontal mass. A 66-year-old woman was admitted with a left nasal intranasal localized tumor without cranial extension and gross total removal was achieved...

We report the case of a young woman who received intrathecal baclofen therapy (ITB) and subsequently became pregnant and had a normal delivery. A 28-year-old woman with flexion myelopathy had anterior decompression with fusion at C4/5 and C5/6 levels. Clinical symptoms improved after surgery. However, when she was 29 years old, her symptoms steadily advanced to Modified Ashworth Scale 3 spasticity level in the lower legs, with pain in both of them and urinary retention tendency. Since a 25 μg intrathecal baclofen injection improved her symptoms, an ITB pump system was implanted...

We report a case of a 24-year-old woman who presented with an uncomfortable feeling in her right foot with a 6-month history of slight weakness in her right hand. Neuroimaging demonstrated irregular shaped lesions in the left thalamus and basal ganglia in addition to spotty lesions in the contralateral thalamus. The MRI showed high-intensity signals on T2-weighted, fluid-attenuated inversion recovery, and diffusion-weighted images. The lesions demonstrated low-intensity signaling on T1-weighted images and were slightly enhanced with gadolinium...

Acetabular fracture usually is related to high-energy traumatic injury or falls from heights and directly caused by seizures without trauma is extremely rare. We report a 71-years-old man who sustained a left acetabular fracture secondary to generalized seizure after clipping of an unruptured aneurysm without trauma and any risk for fracture. The patient had an aneurysm was arising from the bifurcation of the left internal carotid artery and the posterior communicating artery. After the clipping, the patient had three times tonic-clonic seizures for 1 min and resulted in an acetabular fracture...

Bleeding from meningiomas is well known, but massive subdural hemorrhage from a very small meningioma is rare. A 61-year-old woman presented with a sudden-onset headache and slight right hemiparesis without a history of trauma. Computed tomographic scan showed bilateral acute/subacute interhemispheric subdural hematoma, but contrast-enhanced computed tomography (CT) scan, non-enhanced magnetic resonance imaging (MRI) and digital subtraction angiography failed to detect the cause. The hematoma was conservatively treated...

Bilateral vertebral artery dissecting aneurysms (VADAs) with subarachnoid hemorrhage (SAH) are rare and their management is still challenging. In this report, we successfully performed one-stage stent-assisted coil embolization (SAC) for bilateral VADAs with SAH in an acute stage, because the ruptured side could not be diagnosed. A 47-year-old woman presented with a sudden onset of headache without laterality, and left-side dominant SAH with bilateral VADAs was noted on computed tomography (CT) scans. The size of aneurysmal dome and neck was similar between the two VADAs, and a bleb was observed only on the right VADA...

A 31-year-old man presented with a sudden-onset headache, right hemiparesis, and dysarthria on day 0 and was diagnosed with acute ischemic stroke due to dissection of the left intracranial internal carotid artery with middle cerebral artery extension. His symptoms progressed despite the institution of treatment, suggesting progression of the dissection. On day 5 after symptom onset, the patient underwent superficial temporal artery-middle cerebral artery anastomosis. No new ischemic stroke event occurred after surgery...

A 56-year-old man underwent cervical laminoplasty for cervical spondylosis. On the 7th postoperative day, he suddenly felt severe neck pain, and tetraplegia developed rapidly over 1.5 hrs. Computed tomography demonstrated a huge hematoma compressing the cervical spinal cord. Clot was evacuated 3 hrs after the onset of symptoms. The patient's postoperative course was uneventful. His blood pressure could not be properly controlled in the perioperative period. Surgeons should keep in mind that delayed postoperative spinal epidural hematoma (DPSEH) can occur more than a week after surgery, and meticulous blood pressure control is important for more than a week after a spinal operation...

Severe hypoglycemia is known to cause acute focal neurological symptoms. In cases with a medical history of diabetes mellitus (DM), the diagnosis and treatment of hypoglycemia-induced neurological symptoms are simple. However, severe hypoglycemia can occur in patients who are not taking hypoglycemic agents such as insulin or long-acting sulfonylurea drugs. We describe a 95-year-old man with sudden onset of right hemiparesis who showed high signal intensity on diffusion-weighted imaging involving the left internal capsule with corresponding reduced apparent diffusion coefficient hypointensity...

Craniosynostosis associated with Chiari malformation (CM) is usually found in infants with an underdeveloped posterior fossa. We here present a case of adult craniosynostosis, CM, and symptomatic syringomyelia caused by the protrusion of the posterior rim of the foramen magnum without a tight posterior fossa. A 22-year-old woman with an abnormal head shape and forearm hypesthesia was given a diagnosis of sagittal suture synostosis with CM and syringomyelia caused by foramen magnum stenosis. She underwent foramen magnum decompression with a C1 laminectomy without cranial vault expansion or duraplasty...
