A ruptured posterior communicating artery aneurysm presenting as tentorial and spinal isolated subdural hemorrhage: a case report and literature review

BackgroundRuptured intracranial aneurysms are often associated with subarachnoid or intraparenchymal hemorrhage. However, the prevalence of subdural hemorrhage post aneurysmal rupture is low and rarely reported in scientific studies. Here, we report an unusual case of a ruptured posterior communicating artery aneurysm resulting in an isolated subdural hematoma located in the tentorial and spinal canal without subarachnoid or intraparenchymal hemorrhage.Case presentationIn this case, a 34-year-old woman with no history of trauma or coagulopathy was diagnosed with a subdural hematoma in the tentorium cerebellum tracing to the subdural space of the spinal column. Computed tomography angiography was used to identify the source of the bleeding, which revealed a ruptured left-sided posterior communicating artery saccular aneurysm. The aneurysm was clipped, and the hematoma was evacuated. The patient recovered without any neurological complications.ConclusionsOur results suggest that a diagnosis of ruptured intracranial aneurysm should be considered in patients with nontraumatic subdural hematoma. Prompt diagnostic imaging and interventional diagnostic procedures are required to ensure proper management of these patients and to avoid unnecessary complications.

Giant Posterior Communicating Artery Aneurysm Presenting as Trigeminal Neuralgia

We report an extremely rare case of trigeminal neuralgia (TN) caused by a giant posterior communicating artery aneurysm. We describe the case of a 73-year-old man who suffered disabling TN, which was deeply exacerbated when he laid down. Computed tomography angiography and digital angiography revealed an unruptured giant posterior left communicating artery aneurysm projecting to the posterior fossa and contacting the trigeminal root. The size and projection of the aneurysm seemed responsible for both the neuralgia itself and its peculiar clinical characteristic of exacerbation when the patient laid down. The aneurysm was surgically clipped, then opened and emptied to decompress the trigeminal root. The patient reported an immediate complete remission of the neuralgia. The finding of TN secondary to aneurysms is rare but even more in the case of a posterior communicating aneurysm. The clinical clue that should alert physicians about the presence of an aneurysm as the cause of TN is exacerbation of pain by adopting a supine position. Due to the high risk of rupture associated with giant and symptomatic aneurysms, we believe that treatment should be aggressive in this case, not only to solve the symptomatic TN but also to avoid the risk of aneurysm rupture in the future. The treatment selection between surgical clipping or endovascular coiling with or without stenting, depends on patient's clinical condition and the size and shape of the aneurysm.

Posterior communicating artery aneurysm presenting with writing apraxia

Objectives: We report the first case of writing apraxia as the main presenting feature of a posterior communicating artery aneurysm. Cerebral aneurysm usually presents with visual impairment, nausea and vomiting, severe headache and loss of consciousness. Case report: A 58year-old man presented to the neurological department because of writing difficulty, which affected his work as an executive. Detailed clinical examination and supplementary radiological investigations confirmed a posterior communicating artery aneurysm. The patient was treated surgically with clipping of the aneurysm and he had full recovery at clinic review. Conclusion: To the best of our knowledge, there has been no previous report of a posterior communicating artery aneurysm presenting with writing apraxia. Our case is unusual because the patient’s main presenting feature was writing apraxia secondary to a posterior communicating artery aneurysm.

Giant posterior communicating artery aneurysm presenting as third ventricle mass with obstructive hydrocephalus

The case of a giant posterior communicating artery (PCoA) aneurysm is reported in which the initial presentation was coma secondary to obstructive hydrocephalus. The primary radiological diagnosis was a probable craniopharyngioma. A cerebral angiogram revealed a partially thrombosed giant PCoA aneurysm on the right side. The patient underwent pterional craniotomy with aneurysm clipping and thrombectomy to relieve mass effect, and has made a good recovery. Review of the literature documents that giant PCoA aneurysms are rare. This is believed to be the first reported case of a PCoA aneurysm presenting as a third ventricle mass with obstructive hydrocephalus. The magnetic resonance imaging characteristics of those third ventricle masses that mandate vascular workup are discussed.
