OBJECTIVE: Evaluation the efficiency of the telovelar approach for 4th ventricular lesions through identifying and preserving neurovascular structures. METHODS: Forty cases of fourth ventricular tumours using the telovelar approach Results: It provides adequate exposure in all cases. The brainstem and posterior inferior cerebellar artery (PICA) were early identified and preserved in all cases. Potential tumour attachment was observed at the floor of the fourth ventricle in twenty two (55%) cases, 5 of them were brain stem glioma...

Meningiomas are rare in the pediatric age group, more so in the intraventricular location. They arise in the lateral ventricles from the arachnoid cells contained within the choroid plexus, in the third ventricle from the velum interpositum and in the fourth ventricle from the choroids. These tumors are usually large and have an aggressive behaviour. Surgical management of intra-ventricular meningiomas is challenging because of their deep location, large size at presentation and increased vascularity. The authors report two such cases who presented with symptoms of raised intra cranial pressure and on evaluation were found to have associated hydrocephalus...

A Caucasian female previously diagnosed with anorexia nervosa was referred by psychiatric services to the general medical team. She presented with dehydration, vomiting, weakness, a body mass index of 13 kg/m(2) and was treated with intravenous and enteral supplementation. During admission her vomiting worsened and she developed visual hallucinations and confabulation. Neurological examination demonstrated cerebellar signs and bilateral papilloedema on fundoscopy. Subsequent magnetic resonance imaging of the brain revealed a large fourth ventricular tumour causing obstructive hydrocephalus...

Rosette-forming glioneuronal tumour (RGNT) of the fourth ventricle is one of the newly described primary tumours of the central nervous system. These tumours have two components of both neurocytic and glial areas but usually the glial component of the tumour predominates. They have biphasic cytoarchitecture with two elements; neurocytic rosettes resembling Homer-Wright rosettes, and astrocytic component resembling a pilocytic astrocytoma. They are low-grade tumours with lack of histopathological signs of malignancy...

A 33-years-old male patient presented with cardiac arrhythmias, acute shock and multiple organ dysfunction after the surgical removal of a massive epidermoid posterior to the brainstem. The patient initially presented with paraesthesia along the right C6 dermatome due to a big tumour at the brain stem. Surgical removal was performed without adverse events and he was transferred to our intensive care unit (ICU) immediately after the operation. Though initially showing a stable postsurgical course he developed cardiac arrhythmias and a state of acute distributive shock with consecutive multi organ failure...

Ependymomas are glial series tumours that can occur throughout the neural axis, usually in close proximity to the ventricles or central canal. While the fourth ventricle is a common location for ependymoma, we present a rare case of an entirely intraparenchymal infratentorial tumour, remote from the ventricular surface, and discuss the imaging characteristics that may suggest the diagnosis. The histological features, which remain identical despite the varied morphology of intraventricular versus intraparenchymal tumours, are also considered...

Colloid cysts account for approximately 2% of primary brain tumours and the majority of cases are identified in the fourth and fifth decade. They are small, gelatinous neoplasms lined by a single layer of mucin-secreting columnar epithelium that are thought to arise from errors in folding of the primitive neuroepithelium. They develop in the rostral aspect of the third ventricle in the foramen of Monro in 99% of cases and despite their benign histology carry a poor prognosis, with a mortality greater than 10% in symptomatic cases...

BACKGROUND: Ganglioneuroblastomas (GNBs) are rare embryonic neoplasms in the spectrum of neuroblastic tumours and 80% of cases occur in the first decade. In adults, GNBs are usually located in the retroperitoneum, mediastinum and neck but intracranial GNBs are extremely rare. CASE REPORT: A 34-year-old male applied to the Department of Neurology outpatient clinic with a two month history of headache and numbness in his legs. Detailed examinations and cranial CT were performed and showed a mass with a 5 cm diameter running from the third to the fourth ventricle...

INTRODUCTION. Intracranial subependymomas are rare, slow-growing, noninvasive, benign tumors. They are most often located in the fourth ventricle. Most of these tumors are discovered incidentally during autopsy. Routine medical checkups using neuroimaging techniques have increased their diagnosis. Subependymomas may present with symptoms related to cerebrospinal fluid obstruction or mass effect. CASE REPORT. A 52-year-old man presented with severe headache and mental deterioration with memory disturbances and bradypsychia...

Adjuvant cytotoxic chemotherapy following surgical treatment of nonmetastatic breast cancer usually includes an anthracycline. The addition of trastuzumab should be considered for women whose tumours overexpress HER-2 protein. Trastuzumab has been approved in the European Union since 2006 for adjuvant treatment of breast cancer. In 2011, the indications were further specified to allow the use of adjuvant trastuzumab in both anthracycline-based and non-anthracycline protocols. In 2006, the results of the first 3 trials of adjuvant chemotherapy showed an absolute gain in overall survival of about 4% after 4 years with trastuzumab...

BACKGROUND: Choroid plexus papillomas of the third ventricle in newborn infants are quite rare and present a significant surgical challenge. This case report illustrates the utility of endoscopy in facilitating tumor resection. PATIENT: A 6-week-old boy, born prematurely at a gestational age of 35 weeks, presented with hydrocephalus secondary to a choroid plexus papilloma in the third ventricle, extending to the aqueduct of Sylvius and into the fourth ventricle...

BACKGROUND. Phaeochromocytomas and paragangliomas are rare, mostly benign catecholamine-producing tumours of chromaffin cells of the adrenal medulla or of extra-adrenal paraganglia. Phaeochromocytoma may occur at any age, the greatest frequency being in the fourth and fifth decades. Only on extremely rare occasions does the tumour develop in the very old patients. METHODS. We are describing an 86-year-old patient with phaeochromocytoma, presenting with reversible myocardial dysfunction. RESULTS. This very old patient with phaeochromocytoma had hypertension characterized by labile blood pressure values and increased daytime blood pressure variability...

Clear cell meningiomas are rare meningioma variants and are recognized as World Health Organization grade II tumours. They may be difficult to manage given their propensity to recur early especially if present in surgically challenging locations. We describe a rare case of a fourth ventricular clear cell meningioma without dural attachment in a 14-year-old boy with an unusual presentation of failure to thrive. The case is presented in detail and a review of the recent literature is discussed.

Choroid plexus papillomas are rare tumours, which occasionally spread both intracranially and down the spinal canal. Spinal metastasis has been reported infrequently and only once many years since the initial diagnosis. This is the first reported case of late recurrence, metastasis and transformation of a benign to an atypical lesion.

Four cases of pediatric cardiac tumours (PCTs) associated with ventricular arrhythmias are reported. Sudden cardiac death attributable to the tumour occurred in two children. A third child received an implantable cardioverter defibrillator and the fourth had persistent ventricular arrhythmia despite medical therapy. Most PCTs are considered benign; however, the development of malignant arrhythmias may complicate the management of these tumours in some patients. The literature regarding the arrhythmogenic potential of PCTs and the use of implantable cardioverter defibrillators in these patients is reviewed...

We report a case of a 22-year-old man presenting with a fourth ventricular tumour and associated chronic obstructive hydrocephalus likely leading to thinning of the cranium. Intraoperatively, he developed an epidural hematoma secondary to a fracture of the temporal bone by application of the three-point skull fixator. This is the second reported adult case of an iatrogenic epidural hematoma secondary to pin-site complications. We advocate the careful placement of the pins and suggest the tightening force be catered individually especially in pediatric patients or patients with chronic hydrocephalus...

We document the case of a 69-year-old man presenting with 6 weeks of intractable vomiting. Magnetic Resonance Imaging showed a homogenously enhancing mass in the caudal fourth ventricle. Surgical exploration and biopsy was performed and pathological examination demonstrated a high-grade B-cell lymphoma. The lesion was a primary tumour in an immuno-competent patient. Despite the increasing incidence of primary central nervous system lymphomas this is believed to be only the third ever case to have occurred at this rare site...
