A 72-year-old man who had undergone nephrectomy for left renal cell carcinoma (RCC) presented with worsening of cognitive function and frequent loss of consciousness. Computed tomography (CT) revealed tumor mass in the third ventricle and hydrocephalus. A ventriculoperitoneal (VP) shunt was placed to treat the hydrocephalus. The postoperative course was uneventful, and he was followed closely w...

A 45-year-old female patient presented with symptoms of polydipsia and polyuria, menopause, headache, gait disturbance and deteriorated mental state. Brain magnetic resonance imaging (MRI) showed an irregular mass in the anterior third ventricle. The tumor was excised using a transfrontal approach from the anterior section of the third ventricle. The histological diagnosis was of an intracrania...

It has been rather generally accepted that colloid cysts of the third ventricle are derived from persisting remnants of the paraphysis2' 5 as first suggested by Sj6vall6 in 1909. The paraphysis is a variety of extraventricular choroid plexus found best developed in adult forms of the ganoid fishes and certain amphibia, but is present in the embryos of all vertebrates, including man. This struct...

Parkinsonism secondary to intracranial mass lesions usually results from compression or distortion of the basal ganglia. Secondary parkinsonism due to midbrain infiltration or compression is rare and generally associated with other neurologic signs caused by pyramidal tract and/or cranial nerve involvement. We report a case of 30-year-old woman in whom mild parkinsonism was the major clinical m...

INTRODUCTION There have been inconsistent reports of dilation of the third ventricle (lll-V) in bipolar disorder. Within the lateral walls of lll-V are hypothalamic nuclei which mediate the neuroendocrine, sleep, appetite and autonomic disturbances which characterise a depressive episode. METHODS The lll-V width, immediately anterior to the mamillary bodies, was measured in 74 bipolar I or II...

BACKGROUND The neuropeptide galanin increases food intake. Chronic ethanol (EtOH) increases the expression of galanin in the hypothalamus. The research presented here examines the effects of microinjection of galanin in the third ventricle on voluntary alcohol intake. METHODS Male Sprague Dawley rats with a cannula in the third ventricle were given access to increasing concentrations of EtOH ...

tumor found almost exclusively within the fourth ventricle. These grade I tumors were first included in the World Health Organization (WHO) Classification for the central nervous system in 20071. Since then, approximately 49 cases have been published1,2. There are no reported cases of RGNT within the third ventricle, although this tumor has also been described in the pineal region, the tectum a...

Blue rubber blue nevus syndrome: report of a case with consumption coagulopathy complicated by manifest thromboses. A case report: pregnancy complic...

Aims of this morphometric study was to analyze the size of third ventricle in relation to the dimension of diencephelon in humans. Ventricular size of males and females was compared. Changes in normal ventricular size with the corresponding changes in the dimension of diencephelon during ageing was also studied and statistically analyzed .The CT images of 112 adult individuals (Age Group 21-60)...

Colloid cysts are rare benign tumors of the third ventricle with diverse clinical presentation, which vary from incidentally found cysts to acute death. An uncommon hemorrhage in these cysts is a life threatening complication which can cause obstructive hydrocephalus with acute deterioration of the patient and sudden death. We present a case of 35-year-old man with large hemorrh...
