“…Prior reports recommend consideration of "bleeding tendencies" for hemorrhagic cysts. [1] ese reports of hemorrhagic colloid cysts included a patient with a history of hypertension, another with leukemia and chronic thrombocytopenia, and another with recent warfarin use -however, INR, in this case, was found to be normal on presentation. [4,5,8] It is difficult to quantify the risk of hemorrhage in colloid cysts given the limited number of known instances.…”

Background: Colloid cysts characteristically arise from the roof of the third ventricle near the foramen of Monro, causing symptoms from obstructive hydrocephalus. However, atypical locations have been reported with various clinical presentations, growth patterns, and displacement of surrounding anatomic structures. Case Description: Here, we describe the interesting case of a patient with a large hemorrhagic cavum vergae colloid cyst presenting with anterograde amnesia soon after starting antiplatelet therapy. The patient did not have hydrocephalus on presentation and his amnesia persisted after complete removal of the hemorrhagic mass through transcallosal interforniceal approach. Conclusion: To the best of our knowledge, this is the only reported instance of a colloid cyst presenting with amnesia in the absence of hydrocephalus. Pathophysiology as well as diagnostic and management strategies of hemorrhagic colloid cysts are discussed.

“…The potential causes include acute obstructive hydrocephalus and, in rare instances, intracystic hemorrhage referred to as "cyst apoplexy." 8,9,12 The occurrence of hemorrhagic changes within colloid cysts can cause rapid enlargement, ultimately leading to a sudden and total obstruction of cerebrospinal fluid (CSF) circulation. 6,13 There have been a handful of events of hemorrhagic third ventricle cysts described in the literature.…”

“…These cysts are filled with colloid material. 8 9 They originate from the residual endodermal embryonic structures within the brain. Other potential sites include diencephalic ependymoma, the invagination of the neuroepithelium within the ventricle, or the respiratory epithelium of endodermal origin.…”

Hemorrhagic Fourth Ventricle Colloid Cyst: A Report of an Unusual Presentation at an Uncommon Location

Colloid cysts are benign cystic lesions characteristically arising from the third ventricle roof close to the foramen of Monro. Although incredibly rare, hemorrhage within a third ventricular colloid cyst is sparsely reported. To the best of our knowledge, no cases of hemorrhage within the fourth ventricle colloid have ever been documented. Here, we present an interesting case describing a hemorrhagic colloid cyst situated within the fourth ventricle of a 55-year-old female patient who presented with symptoms of headache, vomiting, and gait imbalance. The cyst was excised during surgery via a suboccipital microscopic telovelar approach. Our findings led us to the conclusion that, despite being extremely rare, colloid cysts in the fourth ventricle can present with hemorrhagic episodes, which can exacerbate symptoms and hasten neurological decline. As a result, the presence of unusual radiological characteristics in a fourth ventricle lesion should prompt medical practitioners to suspect an atypical colloid cyst. This consideration can be pivotal in making informed surgical decisions. Expedited management and a microsurgical approach are recommended strategies for a better outcome.

“…9 They may follow a benign course and spontaneously resolve, or may present with lifethreatening complications of acute hydrocephalus, rapid neurological deterioration and sudden death. 8 Clinical suspicion followed by radiological imaging often leads to diagnosis. Mucin secreted by the inner wall of cyst determines the imaging properties.…”

“…6,7 Though they follow a benign course they are often associated with significant morbidity as they may present with acute hydrocephalus and sudden death in a previously asymptomatic individual. 8 Diagnosis is usually based on clinical suspicion followed by radiological methods such as CT and MRI.…”

Colloid cyst: unusual location of petrous temporal bone

Colloid cysts are benign, thin walled spherical neoplasms, composed of a collagenous capsule, underlying epithelium that arises from brain’s epidermal embryonic remnants and a viscous centre. They are shown to approximate 0.5% of all intracranial tumours with no recorded evidence of the petrous temporal bone involvement. Colloid cyst of the petrous temporal bone often presents with clinical symptoms of headache, hearing loss, facial palsy and imbalance/vertigo. Which is diagnosed on radiological and histological findings. Histologically, they are lined by ciliated cuboidal to pseudo stratified columnar epithelium resting on an eosinophilic basement membrane. Imaging Techniques are helpful in early diagnosis and preventing further complications. Here we will be discussing about a 24-year-old female, a known case of petrous apex osseous haemangioma presenting with unstable gait and tingling sensation on one side of face leading to an incidental finding of a colloid cyst on petrous temporal bone through histological examination.
