Sotos syndrome is characterized by overgrowth, macrocephaly, distinctive facial features, and learning disabilities and is associated with alterations in the nuclear receptor binding SET domain protein 1 (NSD1) gene. Due to the advanced bone age, the eventual adult height is usually at the upper limit of normal. In this case report, a 6-year and 10-month old boy who presented with Sotos syndrome was described. He also had increased testicular volumes with advanced bone age. The stimulated levels of gonadotropins revealed central precocious puberty and brain magnetic resonance imaging (MRI) showed a pineal cyst...

An 11-year-old boy presenting with sudden onset double vision, headache and neck pain was found to have left lateral rectus palsy, papilledema and neck rigidity. An initial diagnosis of benign intracranial hypertension was considered. However, magnetic resonance imaging (MRI) of the brain surprisingly discovered the pineal gland cyst. He underwent Krause´s procedure for the excision biopsy of the cyst. Histopathological examination confirmed epidermoid cyst. Postoperatively, he had transient ataxia and upgaze palsy but recovered well...

This case report describes a patient who presented to the emergency department with intermittent visual disturbance and was found to have convergence-retraction nystagmus. This occurred in the setting of supratherapeutic anticoagulation on warfarin for an aortic dissection graft repair. Urgent imaging demonstrated haemorrhagic transformation of a previously identified incidental pineal cyst. After close monitoring given the risk of secondary hydrocephalus, the patient was discharged in stable condition with symptom resolution and without any further significant complications...

Stereotactic biopsies of ventricular lesions may be less safe and less accurate than biopsies of superficial lesions. Accordingly, endoscopic biopsies have been increasingly used for these lesions. Except for pineal tumors, the literature lacks clear, reliable comparisons of these two methods. All 1581 adults undergoing brain tumor biopsy from 2007 to 2018 were retrospectively assessed. We selected 119 patients with intraventricular or paraventricular lesions considered suitable for both stereotactic and endoscopic biopsies...

INTRODUCTION: We present a consecutive case series and a systematic review of surgically treated pediatric PCs. We hypothesized that the symptomatic PC is a progressive disease with hydrocephalus at its last stage. We also propose that PC microsurgery is associated with better postoperative outcomes compared to other treatments. METHODS: The systematic review was conducted in PubMed and Scopus. No clinical study on pediatric PC patients was available. We performed a comprehensive evaluation of the available individual patient data of 43 (22 case reports and 21 observational series) articles...

BACKGROUND: Pineal cysts are common, typically asymptomatic, and are usually found incidentally in adults. In rare cases, pineal cyst apoplexy occurs as a result of an acute cystic hemorrhage. This can result in acute onset of severe headaches, acute obstructive hydrocephalus, mass effect on the midbrain, and even death. Pineal apoplexy is most common in reproductive age women, while pediatric cases continue to be less prevalent. Pineal cyst apoplexy remains a rare entity with 30+ cases presented in the literature to date...

OBJECT: The purpose of this study was to evaluate whether endoscopic third ventriculostomy (ETV) and endoscopic cyst fenestration are effective minimally invasive alternatives to a craniotomy with cyst resection for the treatment of symptomatic pineal cyst-associated aqueductal stenosis. METHODS: Sixteen patients with symptomatic pineal cysts were operatively managed endoscopically and these cases were retrospectively reviewed. There were 12 females and 4 males...

Abnormal melatonin secretion has been demonstrated in patients with affective disorders such as major depressive disorder (MDD) and bipolar disorder (BD). However, magnetic resonance imaging (MRI) studies that previously investigated the volume of the pineal gland, which regulates circadian rhythms by secreting melatonin, in these patients reported inconsistent findings. The present study employed MRI to examine pineal gland volumes and pineal cyst prevalence in 56 MDD patients (29 currently depressed and 27 remitted patients), 26 BD patients, and matched controls (33 for MDD and 24 for BD)...

Background: Whether girls with central precocious puberty (CPP) should undergo routine brain magnetic resonance imaging (MRI) to identify potential intracranial pathologies is controversial. Aims: To evaluate the brain MRI results of girls with CPP and identify the clinical and endocrine predictors of brain abnormalities. Methods: This retrospective study obtained data from pediatric endocrine clinics at Chang Gung Children's Hospital. From 1997 and 2017, 403 girls were consecutively diagnosed with CPP. After the exclusion of patients with a history of central nervous system (CNS) insults or associated neuropsychiatric symptom or signs, we studied the prevalence of brain abnormalities in 251 girls with CPP who received detailed MRI examinations of the hypothalamus and pituitary area...

Pineal cysts (PCs) are often encountered as incidental findings in intracranial images. The vast majority of cysts are normally asymptomatic and clinically benign. Bleeding into the cysts, which leads to neurological symptoms and signs, is considered to be quite rare. The authors illustrate a newly identified complication of PC in a 56-year-old woman who characterized by headache of sudden onset and vomiting. MRI disclosed a small hemorrhagic PC without narrowing of the cerebral aqueduct. The patient was managed conservatively without any surgical interventions, and she remained symptom-free over a period of 15-year follow-up...

Arachnoid cyst is a rare benign cerebrospinal fluid-filled cyst that can develop anywhere in the brain along the arachnoid membrane and usually unaccompanied by the anomalous development of the brain structure. These cysts are usually located in the middle cranial fossa. However, they are also denoted in other regions. Arachnoid cysts are mostly asymptomatic and diagnosed incidentally. Spontaneous regression of arachnoid cysts in different anatomical regions of the brain has been reported in the literature...

OBJECTIVE: The midline supracerebellar infratentorial (SCIT) approach and its paramedian development are commonly used for dealing with pineal lesions. Comparative clinical studies are lacking, however. We aim to establish the better performance of the paramedian SCIT approach in terms of clinical safety in surgically treated pineal cysts and pineal region tumors. Procedural functionality and effectiveness have been also analyzed. METHODS: A comparative analysis of clinical, radiologic, pathologic, and surgical features, and outcome was performed between 55 midline and 57 paramedian SCIT approaches that were exclusively performed in 112 patients (57 pineal cysts and 55 tumors of the pineal region) operated in sitting position by a single surgeon...

BACKGROUND: Pineal lesions are common causes of dorsal midbrain syndrome and typically require surgical intervention in symptomatic patients. We describe a unique case of spontaneous resolution of dorsal midbrain syndrome resulting from a pineal gland cyst. CASE DESCRIPTION: A 23-year-old woman developed a supranuclear upgaze palsy, convergence-retraction nystagmus, and light-near dissociation from a pineal gland cyst (1.0 × 1.3 × 1.2 cm) with mild mass effect on the posterior surface of the tectum...

Intracranial growing teratoma syndrome (iGTS) is rare phenomenon which is observed in non-germinomatous germ cell tumor (NGGCT) after chemotherapy. The clinical features of iGTS are rapidly increasing in size compared with relapse, no elevation of tumor marker in spite of tumor regrowth, multiple cystic lesions in cranial imaging, and histopathologically diagnosed as mature teratoma. Here we present a 14-year-old man with iGTS which was revealed at 44 months after initial chemotherapy. He was diagnosed as pineal immature teratoma by histopathological specimen, and we performed chemotherapy and radiation therapy...

Background: Microsurgical resection represents a well-accepted management option for symptomatic benign pineal cysts. Symptoms such as a headache, hydrocephalus, and visual deficiency are typically associated with pineal cysts. However, more recent studies reported over the past years have characterized additional symptoms as a part of the clinical manifestation of this disease and represent additional indications for intervention. Methods: We present a retrospective review of patients with histologically confirmed benign pineal cysts that were operated on in our department between 1997 and 2015...
