Effects of Lumbar Fusion Instrumentation Removal in Patients Who Experienced Continued Pain After Lumbar Spinal Fusion Surgery for Lumbar Degenerative Disease.

Aim: To investigate the visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores after the removal of the instrumentation system in patients who underwent lumbar instrumentation for lumbar degenerative disease (LDD).

Material And Methods: This study included 30 patients (19 female, 11 male) who had undergone posterior lumbar instrumentation for LDD in whom postoperative continuous or recurrent pain led to the removal of the implant system in our clinic between December 2013 and December 2019. The patients had continuous or recurrent low back pain that did not respond to medical treatment, physical therapy, or any type of lumbar block.

Pituitary carcinoma presenting with multiple metastases: case report.

Pituitary carcinoma, an uncommon tumor in adults, generally presents with craniospinal and systemic metastases. We report a case of pituitary carcinoma with multiple craniospinal metastases in a child. A 9-year-old girl, who had had a ventriculoperitoneal shunt operation 3 years ago, presented with complaints of progressive visual disturbance, headache, speech difficulty, and gait disturbance for the past 2 months.

Isolated internal auditory artery aneurysm.

Anticoagulant therapy is effective and prevents death in more than 95% of patients with pulmonary embolism following deep vein thrombosis. We report a patient who developed deep vein thrombosis following rupture of a dissecting aneurysm of the internal auditory artery. The parent artery was occluded before anticoagulant therapy as a prophylactic measure to prevent intracranial haemorrhage.

Cerebellar abscess and syringomyelia due to isoniazid-resistant Mycobacterium tuberculosis.

A 19-year-old immunocompetent man was admitted to hospital with diplopia, nausea, vomiting and change in mental status. The patient had a history of tuberculous meningitis that was diagnosed at another hospital 6 months before the present admission, and at that time anti-tuberculosis treatment was initiated using a first-line drug combination. A computed tomography (CT) scan of the brain revealed non-communicating hydrocephalus.

Middle cerebral artery aneurysm associated with Behçet's disease--case report.

A 37-year-old man with Behçet's disease suffered secondary subarachnoid hemorrhage and intracerebral hematoma in the right temporal lobe caused by a ruptured aneurysm of the right middle cerebral artery. The aneurysm was successfully clipped. Aneurysm formation is common in the visceral arteries in Behçet's disease, but extremely rare in the intracranial arteries.

Intraventricular solitary fibrous tumor: an unusual tumor with radiological, ultrastructural, and immunohistochemical evaluation: case report.

Objective And Importance: Intracranial solitary fibrous tumors have been described previously, but intraventricular solitary fibrous tumors are extremely rare. We present what is, to our knowledge, the first reported case of solitary fibrous tumor in the third ventricle.

Clinical Presentation: A 63-year-old man presented with weakness of his lower extremities and headaches.
