Insights

This is the first reported case of primary central nervous system (CNS) vasculitis presenting with branch retinal artery occlusions and subsequent brain calcification in a 39-year-old woman.

Area of Science:

  • Neurology
  • Ophthalmology
  • Pathology

Background:

  • Central nervous system (CNS) vasculitis is a rare condition characterized by inflammation of blood vessels in the brain and spinal cord.
  • Branch retinal artery occlusions (BRAOs) are typically associated with embolic or thrombotic events, but can rarely be a manifestation of systemic or CNS vasculitis.

Observation:

  • A 39-year-old woman experienced multiple BRAOs.
  • Three years later, she developed a calcified mass in the left frontal lobe.
  • Brain biopsy confirmed small vessel vasculitis, ischemic necrosis, and dystrophic calcification.

Findings:

  • The patient presented with a unique combination of BRAOs and primary CNS vasculitis.
  • The CNS vasculitis led to ischemic brain damage and subsequent calcification in the affected area.
  • This case highlights a potential, albeit rare, ocular manifestation preceding neurological symptoms in CNS vasculitis.

Implications:

  • This case expands the known clinical spectrum of primary CNS vasculitis.
  • It suggests that BRAOs may be an early indicator of underlying CNS vasculitis, even before overt neurological signs appear.
  • Further research is needed to understand the pathogenesis and diagnostic challenges of CNS vasculitis with associated ocular and cerebral calcification.

Diabetic Retinopathy01:27

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Arteries of the Head and Neck01:26

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
The Arch of Aorta01:10

The Arch of Aorta

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...
Glaucoma: Overview01:25

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
Anatomy of the Eyeball01:20

Anatomy of the Eyeball

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
