Acute hydrocephalus caused by a colloid cyst - a case report

Ominous Causes of Headache

PURPOSE OF REVIEW

While primary headaches like migraines or cluster headaches are prevalent and often debilitating, it's the secondary headaches-those resulting from underlying pathologies-that can be particularly ominous. This article delves into the sinister causes of headaches, underscoring the importance of a meticulous clinical approach, especially when presented with red flags.

RECENT FINDINGS

Headaches, one of the most common complaints in clinical practice, span a spectrum from benign tension-type episodes to harbingers of life-threatening conditions. For the seasoned physician, differentiating between these extremes is paramount. Headache etiologies covered in this article will include subarachnoid hemorrhage (SAH), cervical artery dissection, cerebral venous thrombosis, meningitis, obstructive hydrocephalus, and brain tumor.

Colloid Cyst Presenting With Severe Headache and Bilateral Leg Weakness: Case Report and Review

Colloid cysts are benign growths commonly found in the third ventricle at the foramen of Monro. They can be asymptomatic or present with a variety of symptoms, including headaches, diplopia, memory problems, psychosis, urinary incontinence, and ataxia. Obstructive hydrocephalus from a colloid cyst is caused by a blockage of cerebral spinal fluid (CSF) from the lateral ventricles at the foramen of Monro. Colloid cysts have rarely been reported to cause sudden death. Here we present the case of a 32-year-old female with a known history of a colloid cyst who presented with a headache and transient weakness in her lower extremities noted while climbing stairs.

Acute hydrocephalus caused by colloid cyst of third ventricle: A case report

Colloid cysts (CCs) of third ventricle are rare benign lesions. They present with acute hydrocephalus and its sequalae like brain herniation, infarcts resulting even death in otherwise healthy individual. We present a case of an acute hydrocephalus caused by CC of third ventricle. A middle age male was airlifted from a remote district of Nepal to our hospital with no accompanying doctor. The patient had headache, multiple episodes of vomiting, abnormal body movement, and loss of consciousness for 24 hours. On examination, vitals were stable; the Glasgow Coma Scale (GCS) score was 7. The patient was intubated in emergency and an MRI brain was done. MRI showed an obstructive lesion in third ventricle with features consistent with CC and an active hydrocephalus. There were multifocal infarcts in the bilateral cerebrum, left part of mid brain and pons, left thalamus and left superior cerebellum. We inserted external ventricular drainage in emergency operation theatre within hours and endoscopic excision of the lesion was done on the next day. In histopathology, the lesion was confirmed to be a CC.

A quadrigeminal arachnoid cyst as a cause of neurological symptoms in an 11-month-old Brussels Griffon - A case study

An intracranial arachnoid cyst (IAC) is a rare developmental disorder that is consistent with cerebrospinal fluid accumulation between the brain and the arachnoid membrane. A quadrigeminal cyst is a specific type of cyst that is identified based on its localization. To the best of our knowledge, this is the first study to report on this type of pathology in a Brussels Griffon. This case study describes an 11-month-old female Brussels Griffon with symptoms of reluctance to lower the head and eat from a bowl placed on the ground, combined with episodes of vocalization. The patient was subsequently diagnosed with a quadrigeminal cyst during a low-field magnetic resonance imaging (MRI) exam, and she tested positive for toxoplasmosis in the blood test. Arachnoid cysts are often described as incidental findings, but the characteristics of neurological symptoms in the presented patient suggest that the cyst was clinically significant. The currently known options of pharmacological and surgical treatment give some hope for symptomatic patients, although their definitive success rate is not yet fully known.
