OBJECTIVE: We aimed to determine the long-term effects of Gamma knife radiosurgery (GKS) on remnants in the cavernous sinus (CS) after transsphenoidal surgery (TSS) for acromegaly and to identify its possible adverse effects. METHODS: Thirty patients who had remnant tumors only inside the CS after TSS and who consequently underwent GKS were included. They were followed for a median period of 47 months after GKS with regular hormonal and radiological examinations...

BACKGROUND: The exact location of a hematoma in relation to the pachymeninges contributes to typical radiographic presentations. However, because of the complexity of hematoma evolution and neomembrane formation, an unexpected intraoperative finding may lead to a change of surgical strategy. Besides, the concentration of hemoglobin and its degradation products, the integrity of red blood cells (RBCs), and the infiltration of fibroblasts, polymorphonuclear neutrophils, and macrophages are factors that affect the imaging characteristics on computed tomography (CT) and magnetic resonance imaging (MRI) as the hematoma ages...

REVIEW
Evangelos Drosos, Dimitrios Giakoumettis, Alexandros Blionas, Andreas Mitsios, Georgios Sfakianos, Marios Themistocleous
BACKGROUND: Pediatric non-missile penetrating head injury (NMPHI) is usually accidental attributed mainly to the softer skulls of growing children. However, it is a rather rare entity and therefore no consensus exists regarding treatment, in order to effectively prevent the immediate and long-term complications. Throughout the literature practice, essentials are mostly discussed in case reviews and case series in general population. No data originating from randomized studies are available due to ethical and practical limitations...

BACKGROUND DATA: The effects of chronic corticosteroid therapy on complications, readmission, and reoperation after posterior lumbar fusion (PLF) remains under-investigated and was examined to determine differences in outcomes. METHODS: We analyzed patients from 2006 to 2013 using the National Surgery Quality Improvement Program database (NSQIP) undergoing PLF. Patients taking steroids for a chronic condition were compared to those not taking steroids. Multivariable regression identified factors independently associated with complications, readmission, and reoperation...

BACKGROUND: Complex hydrocephalus affecting lateral and fourth ventricles separately is occasionally managed with CSF diversion via supra- and infra-tentorial ventricular catheters. The optimal configuration to reduce complications is currently unknown in adults. We describe a consistently similar clinical presentation of patients with complex hydrocephalus and a fourth ventricle separately drained by infra-tentorial shunt insertion. METHODS: A retrospective single centre case series...

BACKGROUND: Entrapment of the temporal horn, known as isolated lateral ventricle (ILV), is a rare type of noncommunicating focal hydrocephalus, and its standard treatment has not been established. Here, we report two cases of endoscopic surgery for ILV, and highlight the anatomical surgical nuances to avoid associated surgical risks. CASE DESCRIPTION: The authors present two surgical cases with ILV treated by endoscopic surgery. The first patient with recurrent ILV, due to shunt malfunction, following the initial shunt placement for ILV...

BACKGROUND: Glioblastomas in the sellar region are very rare; in most cases, the tumor originates from the optic nerve/optic chiasm. Only 4 cases of sellar glioblastoma with a non-optic origin have been reported. We present such a case with detailed clinical, imaging and histopathological information. A review of similar published cases is also presented. CASE PRESENTATION: A 42-year-old woman presented with endocrinological abnormalities including, amenorrhea and lactation, symptoms of diabetes insipidus and signs of elevated ICP...

OBJECTIVE: The ongoing aging of our society leads to a rising number of elderly patients with progressive degeneration of the spine, associated with synovial cysts. In the elderly, surgical treatment may be particularly challenging because of comorbidities. METHODS: Patients treated in our department between 1999 and 2014 for spinal synovial cysts were screened. The 28 patients aged 75 years and older were classified as "elderly". Those were compared with 96 patients between 50 and 74 years...

BACKGROUND: Aortic pseudoaneurysms are a rare cause of chronic back pain, usually due to compression of adjacent neurovasculature. It is uncommon for patients with pseudoaneurysms of the abdominal aorta to present in a delayed fashion after initial traumatic injury. CASE DESCRIPTION: We present an unusual case of delayed pseudoaneurysm formation, with subsequent erosion into the adjacent L1 vertebral body. This pseudoaneurysm was secondary to a gunshot wound with retained ballistic fragment that occurred 27 years prior...

Recent literature strongly challenged indications to perform preventive surgery in unruptured AVM. claiming that invasive AVM treatment is associated with a significant risk of complications and thus conservative management may be a preferable alternative in many patients. On the other hand, the recent improvement of surgical instrumentation and treatment strategies (both surgical and interventional) yielded much better outcomes than those achieved only a decade ago. Therefore, even among the specialists, a wide variety of opinions, concerning the treatment of unruptured AVM, can be found...

BACKGROUND: Spinal lipomas are generally thought to occur as a result of failed primary neurulation. Failed primary neurulation allows invasion of mesenchymal tissue of mesodermic origin into the neural structure, leading to the formation of a spinal lipoma. Despite most spinal lipomas being regarded as the result of failed primary neurulation, some confusion in terms of the embryogenesis of spinal lipomas remains. Recently, a novel classification of spinal lipomas based on embryonic changes seen during primary and secondary neurulation was has been proposed...

BACKGROUND: PulseRider (Pulsar Vascular, Los Gatos, CA, USA) is a new endovascular device designed to treat wide neck bifurcation intracranial aneurysms. Deployment of a stent through a PulseRider to treat an aneurysm's recurrence has never been described before. CASE DESCRIPTION: We report the case of a 55-year-old man who underwent coiling of a 8 mm anterior communicating artery aneurysm with assistance of a PulseRider neck reconstruction device. The 6-month digital subtraction angiography control showed aneurysm recurrence, so we deployed an Enterprise 2 closed-cell stent (Codman, Miami Lakes, FL, USA) in the A1-A2 segment passing across the previously implanted PulseRider...

BACKGROUND: Patients with bitemporal lobe epilepsy are generally not considered for surgical resection. Fortunately, responsive neurostimulation proves another avenue for the management of this challenging disease process. In conjunction with our epileptologist, we consider responsive neurostimulation for patients who have clinical features of temporal lobe epilepsy without clear localization on imaging and stereo-EEG. METHODS: Here we describe our technique for implanting a responsive neurostimulator (NeuroPace, NeuroPace Inc...

Only a few cases of intraventricular hydatid cysts have been described. The Camalote or waterlily sign is described when there is detachment of the endocyst membrane, resulting in a floating appearance like a waterlily. This sign has been described most commonly in hepatic cysts. Here, we describe the camalote sign in an iatrogenically ruptured intraventricular hydatid cyst. Rupture of an intraventricular hydatid cyst poses the threat of widespread dissemination and is described in our case.
