Variations of normal development and benign incidental anomalies are frequently observed on diagnostic neuroimaging. It is important these are recognised for what they are, as misinterpretation may result in unnecessary further investigation, follow-up imaging and anxiety. In this article, we review benign intracranial anomalies commonly referred to our unit for specialist neuroradiology advice or multidisciplinary discussion, concerning cysts of the pineal gland and pituitary fossa, vascular anomalies, and perivascular spaces...

Papillary tumor of the pineal region (PTPR) is a neuroepithelial neoplasm first described in 2003. Despite the anatomic association of PTPR with the pineal gland, the features of these tumors resemble those of the ependymal circumventricular subcommissural organ (SCO) of the posterior third ventricle. Given the presumed distinct derivation of PTPR and pineal parenchymal tumors, we hypothesized that expression of lineage-specific transcription factors could distinguish these tumors and provide additional insight into the differentiation of PTPR...

In this short review, the authors performed a database search and summarize current knowledge of the management of patients with pineal cysts (PCs) and investigate the role of surgical treatment. The scientific literature on the surgical treatment of PCs is sparse and encompasses only case series with little over 200 operated patients combined. All included papers reported favorable results after pineal cyst surgery with improvement of symptoms in most patients. Microsurgical resection of PCs, preferably using the supracerebellar-infratentorial approach, could be considered as a viable treatment option in symptomatic patients...

OBJECTIVE The endoscopic third ventriculostomy (ETV) is an established and effective treatment for obstructive hydrocephalus. In its most common application, surgeons plan their entry point and the endoscope trajectory for the procedure based on anatomical landmarks, then control the endoscope freehand. Recent studies report an incidence of neural injuries as high as 16.6% of all ETVs performed in North America. The authors have introduced the ROSA system to their ETV procedure to stereotactically optimize endoscope trajectories, to reduce risk of traction on neural structures by the endoscope, and to provide a stable mechanical holder of the endoscope...

BACKGROUND: A pineal cyst is a relatively common benign condition of the pineal gland. The clinical management of patients with a pineal cyst remains controversial, especially when patients present with non-specific symptoms. METHODS: We performed a prospective study between 2000 and 2016. All patients with a pineal cyst larger than 7 mm were included. Epidemiological data, presenting symptoms, surgical results and radiographic and clinical follow-up were documented...

A subset of patients experience persistent symptoms after pediatric concussion, and magnetic resonance imaging (MRI) is commonly used to evaluate for pathology. The utility of this practice is unclear. We conducted a retrospective cohort study to describe the MRI findings in children with concussion. A registry of all patients seen at our institution from January 2010 through March 2016 with pediatric sports-related concussion was cross-referenced with a database of radiographical studies. Radiology reports were reviewed for abnormal findings...

Preoperative diagnosis of cerebral echinococcosis in an unusual location is always difficult. Nonetheless, this possibility should be kept in mind in all cystic lesions of the brain. Although total excision of the cyst without rupture is a time - tested treatment, but in order to prevent recurrence, adjuvant medical treatment should also be started. Albendazole, mebenadazole and praziquental are commonly used drugs. Albendazole is a drug of choice. Its usual dose for adults is 400 mg twice daily. Exact duration of treatment is still uncertain, but it should not be <6 months...

A pineal cyst is a benign affection of the human pineal gland on the borderline between pathology and normality. Only a small percentage of patients present with symptoms and a surgical treatment is indicated in highly selected cases. A melatonin secretion in patients with a pineal cyst before and after a pineal cyst resection has not been studied yet and the effect of surgery on human metabolism is unknown. The present study examined melatonin, cortisol and blood glucose secretion profiles perioperatively in a surgical group of 4 patients...

BACKGROUND: We have previously proposed that pineal cysts (PCs) may result in crowding of the pineal recess, causing symptoms due to compression of the internal cerebral veins and central venous hypertension. In the present study, we compared clinical outcome of different treatment modalities in symptomatic individuals with non-hydrocephalic PCs. METHODS: The study included all patients managed surgically for non-hydrocephalic PCs in our Department of Neurosurgery over a 10-year period...

OBJECTIVE Cystic lesions of the pineal gland are most often uncomplicated benign lesions with typical MRI characteristics. The authors aimed to study pineal lesion characteristics on MRI to better distinguish benign pineal cysts from other pineal region malignancies as well as to determine which characteristics were predictive of the latter malignancies. They also aimed to study risk factors predictive of hydrocephalus or malignancy in patients harboring these lesions. METHODS The authors performed a retrospective review of a prospectively compiled database documenting the outcomes of patients with suspected pineal cysts on MRI who had presented in the period from 1998 to 2004...

Structural MRI of volunteers deemed "normal" following clinical interview provides a window into normal brain developmental morphology but also reveals unexpected dysmorphology, commonly known as "incidental findings." Although unanticipated, these anatomical findings raise questions regarding possible treatment that could even ultimately require neurosurgical intervention, which itself carries significant risk but may not be indicated if the anomaly is nonprogressive or of no functional consequence. Neuroradiological readings of 833 structural MRI from the National Consortium on Alcohol and NeuroDevelopment in Adolescence (NCANDA) cohort found an 11...

Patients with familial/heritable retinoblastoma (RB) are at increased risk of developing second malignancies throughout life, including a pineoblastoma (trilateral RB [TRB]) in early childhood. Current guidelines recommend regular surveillance brain imaging for those with heritable RB until 5 years of age. The presence of pineal cysts has been reported in patients with RB. Pineal cysts are thought to arise due to focal degeneration of the pineal gland and can be found incidentally. The finding of pineal abnormalities including cysts in children with RB on imaging is disconcerting, as it raises the possibility of an underlying malignancy, specifically a pinealoblastoma...

INTRODUCTION: The pineal region is a deep-seated part of the brain surrounded by highly eloquent structures. Differential diagnosis of space-occupying lesions in this region encompasses pineal gland cysts, pineal gland tumours, metastases, germ cell tumours, meningiomas, gliomas, hemangioblastomas and neuroectodermal tumours. A treatment strategy is based mainly on tumour anatomical characteristics and histological type. Except germinatous tumours, a surgical excision is the treatment of choice...

INTRODUCTION: Pineal cysts are a relatively frequent incidental finding in imaging tests; yet, pineal apoplexy is considered to be rare and is associated to severe symptoms. CASE REPORTS: We report the cases of a 25-year-old male and a female aged 15 years who visited the emergency department with signs and symptoms of intracranial hypertension. The existence of a pineal haemorrhage was confirmed by imaging tests. They were successfully treated by means of microsurgery...

The pineal gland produces the hormone melatonin, and its volume may influence melatonin levels. We describe an innovative method for estimating pineal volume in humans and present the association of pineal parenchyma volume with levels of the primary melatonin metabolite, 6-sulfatoxymelatonin. We selected a random sample of 122 older Icelandic men nested within the AGES-Reykjavik cohort and measured their total pineal volume, their parenchyma volume, and the extent of calcification and cysts. For volume estimations we used manual segmentation of magnetic resonance images in the axial plane with simultaneous side-by-side view of the sagittal and coronal plane...

BACKGROUND: In symptomatic individuals with non-hydrocephalic pineal cysts (PCs), it remains controversial what causes the symptoms. Based on magnetic resonance imaging (MRI) biomarkers, we proposed that PC-associated crowding of the pineal recess may cause central venous hypertension. The aim of this study was to compare pulsatile and static ICP in patients with PCs and chronic daily headache (CDH), and compare ICP data in PC patients with the previously identified MRI biomarkers. METHODS: All patients assessed with over-night ICP monitoring for PCs or CDH who had been ruled out for idiopathic intracranial hypertension without papilledema (IIHWOP) were retrieved from the database...
