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...

A combination of trauma and a missed inflammatory response (nasal operation) concomitant with hydrocephalus and tumor in secondary encephalocele has not been described in the English literature yet. A 38-year-old man was admitted to the clinic with rhinorrhea that started 3 months ago. In his medical history, nothing abnormal was present except a nasal operation performed 1 year ago. Brain magnetic resonance imaging depicted left frontal encephalocele concomitant with obstructive hydrocephalus caused by an epidermoid cyst originated from the pineal region...

BACKGROUND: Pineal tumors are very uncommon intracranial lesions, and endodermal cysts in this location are extremely rare. CASE DESCRIPTION: A 49-year-old right-handed female presented with 3 weeks history of progressive dizziness and imbalance. Imaging studies showed 1.8 cm × 1.7 cm × 1.8 cm pineal lesion with small enhancing mural component displacing ventrally the quadrigeminal plate and narrowing of aqueduct of Sylvius without hydrocephalus. In addition, she was found with small interhemispheric lipoma, and small posterior falx possible meningioma...

Takotsubo syndrome (TTS) is an acquired transient type of systolic dysfunction which mimics myocardial infarction clinically and electrocardiographically. TTS is also known as stress cardiomyopathy, broken heart syndrome, apical ballooning, reversible acute heart failure, neurogenic stunned myocardium or acute catecholamine cardiomyopathy. This case report describes an uncommon presentation of myocardial stunning after an anesthetic procedure. A 14-year-old girl with a history of pineal cyst and hemiplegic migraine was admitted for control brain magnetic resonance imaging...

Teratomas are neoplasms comprising of tissues derived from more than one germ layer. Most common sites are gonads, sacrococcygeal, mediastinal, retroperitoneal, and pineal region. Here, we report a case of 2 -year-old previously healthy female toddlerwho presented with fever and right upper quadrant abdominal pain. Magnetic resonance imaging (MRI) of the abdomen revealed a right suprarenal nonenhancing cystic mass. Focal calcification was seen in the inferomedial aspect of the cyst. Complete surgical resection of the right adrenal gland was done...

INTRODUCTION: Pineal cysts are a common incidental finding on brain MRI with resulting difficulties in differentiation between normal glands and pineal pathologies. The aim of this study was to assess the size and morphology of the cystic pineal gland in children (0-5 years) and compare the findings with published pineoblastoma cases. METHODS: In this retrospective multicenter study, 257 MR examinations (232 children, 0-5 years) were evaluated regarding pineal gland size (width, height, planimetric area, maximal cyst(s) size) and morphology...

Intracranial ectopic germinomas are often associated with synchronous midline disease. Germinomas involving the corpus callosum are exceedingly rare. The reported imaging appearance is not as varied as one might expect and a review of the literature reveals a few common imaging features amongst most ectopic lesions, including cyst formation. We report a 24-year-old man with panhypopituitarism. Neuroimaging revealed three enhancing lesions involving the pituitary infundibulum, the pineal region, and a parenchymal lesion involving the genu of the corpus callosum...

BACKGROUND: While most pineal cysts (PCs) are asymptomatic, some PCs are accompanied with symptoms of variable severity. We suggested that symptom severity in symptomatic patients with non-hydrocephalic PCs relates to venous compression causing central venous hypertension. This study explored whether possible magnetic resonance imaging (MRI) biomarkers of central venous hypertension could differentiate the severity of symptoms in individuals with non-hydrocephalic PCs. METHODS: The study included all individuals with PCs and MRI available for analysis followed conservatively within the department from 2003 to 2014...

OBJECTIVE: The natural history of incidental pineal cysts is poorly understood. Neurosurgeons and neuroradiologists are more frequently faced with this disease in the advent of higher-resolution magnetic resonance imaging (MRI) scanning. We aim to suggest a suitable surveillance strategy for these patients. METHODS: All patients who had MRI of the brain between June 2007 and January 2014 (n = 42,099) at The Walton Centre for Neurology and Neurosurgery were included...

BACKGROUND: A pineal cyst is a benign affection of a pineal gland on the borderline between a pathological lesion and a variant of normality. Clinical management of patients with a pineal cyst remains controversial, especially when patients present with non-specific symptoms. METHODS: An online questionnaire consisting of 13 questions was completed by 110 neurosurgeons worldwide. Responses were entered into a database and subsequently analysed. RESULTS: Based on data from the questionnaire, the main indication criteria for pineal cyst resection are hydrocephalus (90 % of the respondents), Parinaud's syndrome (80 %) and growth of the cyst (68 %)...
