Metastases from tumors to systemic cancers are rare. The most common intracranial recipient tumor is meningioma. Metastasis from gallbladder cancer has been previously reported from only one patient during autopsy. We present the case of a 72-year-old woman who underwent surgery for right frontal skull base meningioma.The tumor was completely removed. Histological specimens showed gallbladder carcinomatous metastasis with diffuse neuroendocrine differentiation in meningothelial meningioma. The Ki-67 proliferation index of the meningioma was 3%...

AIM: To investigate risk factors for surgical site infection (SSI) after three-column osteotomy (3CO) for spinal deformity. MATERIAL AND METHODS: The American College of Surgeons National Surgical Quality Improvement Program database (2012 - 2014) was reviewed. We included adult patients who underwent 3CO and compared pertinent cases (SSI) to controls (no SSI) in terms of preoperative and operative characteristics. Patients with clean/contaminated, contaminated, and dirty/infected wounds were excluded...

Treatment of aggressive pituitary tumors may be challenging. Temozolomide (TMZ) is a promising agent when conventional treatment methods fail. We present three patients with aggressive pituitary tumors with atypical morphology, who were resistant to conventional treatments and treated with TMZ. First case had a somatotroph adenoma, second a corticotroph adenoma, and the third a macroprolactinoma. We also reviewed the literature reporting TMZ efficacy in somatotroph, corticotroph and mammotroph tumors of pituitary...

AIM: Oblique lateral interbody fusion (OLIF) is a minimally invasive surgical method that can access lumbar spine without direct dissection of psoas muscle and the need for intraoperative neuromonitoring (IOM) is questionable. The purpose of this study is to examine and document the transient and persistent perioperative complications in patients who underwent OLIF for degenerative lumbar disease without IOM. MATERIAL AND METHODS: Total 129 consecutive patients who were diagnosed as degenerative spinal disease from L1 to S1 and underwent the mini-open OLIF, were identified and retrospectively reviewed...

Skull Bone fixation following different cranial surgeries is essential and should be rigid, simple and cheap. We describe our technique of cranial fixation using the adhesive cyanoacrylates. MATERIALS AND METHODS: At the end of cranial and intracranial surgeries the craniotomy flap and bone pieces are returned, realigned and fixed using Histoacryl® (N-Butyl Cyanoacrylate) glue. The glue is applied all around the flap in 360 degrees fashion. RESULT: The adhesive material was used in 24 cases after different surgeries involving the calvaria of the skull...

Concomitant occurrence of severe extracranial large vessel stenosis and an ipsilateral intracranial aneurysm is often detected incidentally, but the optimal therapeutic strategy is not clear. Several reports have investigated whether simultaneous carotid artery stenting and coil embolization, or multi-stage therapy is better. These treatment strategies are still controversial because simultaneous therapy will decrease the risk of aneurysm rupture, but may also increase the risk of thromboembolic complications...

Simultaneous presence of the persistent primitive trigeminal artery and so-called intermediate communicating artery in a 77-years-old cadaver autopsied due to the myocardial infarction was discovered. Many vascular variants and abnormalities such as an aplasia of the right vertebral artery (VA), a presence of two right posterior cerebral arteries (PCAs), partial duplication of the right superior cerebellar artery, hypoplasia of the pre-communicating part (A1) of the right anterior cerebral artery and the right PCA of basilar origin, a special configuration of the anterior communicating artery (ACoA), and a small aneurysm at the right A1-ACoA junction were associated...
