The Arch of Aorta

2.3K
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Cranial and Spinal Meninges

4.9K
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Summary

A rare variant of perimesencephalic subarachnoid hemorrhage (PSAH) presents with blood in the quadrigeminal cistern. This quadrigeminal PSAH pattern, often nonaneurysmal, requires thorough vascular imaging to rule out aneurysms.

Area of Science:

  • Neurology
  • Neuroradiology
  • Neurosurgery

Background:

  • Perimesencephalic subarachnoid hemorrhage (PSAH) is a subtype of nonaneurysmal subarachnoid hemorrhage.
  • A rare variant, quadrigeminal PSAH, is characterized by blood centered in the quadrigeminal cistern.

Purpose of the Study:

  • To present three cases of quadrigeminal PSAH.
  • To investigate the characteristics and potential etiologies of quadrigeminal PSAH.

Main Methods:

  • Retrospective review of medical records of patients undergoing digital subtraction angiography for non-traumatic subarachnoid hemorrhage (SAH) between July 2002 and April 2012.
  • Exclusion of patients with anterior circulation aneurysms.
  • Identification of pretruncal and quadrigeminal PSAH patterns on noncontrast CT scans by two blinded reviewers.

Main Results:

  • Three cases of quadrigeminal PSAH were identified.
  • Two patients with quadrigeminal PSAH had nonaneurysmal SAH, and one had a posterior circulation aneurysm.
  • Seventeen patients (16%) had pretruncal PSAH, none with aneurysms.
  • The quadrigeminal pattern represented 11% of pretruncal or quadrigeminal nonaneurysmal PSAH cases.

Conclusions:

  • A subset of nonaneurysmal PSAH cases exhibit a quadrigeminal cistern blood pattern.
  • The etiology of quadrigeminal PSAH may resemble that of classic pretruncal PSAH.
  • Thorough vascular imaging, including multiple digital subtraction angiograms, is crucial for all PSAH patients to exclude aneurysms.
