Accessory Structures of the Eye01:17

Accessory Structures of the Eye

1.9K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Glaucoma: Overview

718
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...

Cranial Bones: Lateral View

2.5K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Veins of Head and Neck01:19

Veins of Head and Neck

2.7K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

2.7K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

Sutures of the Skull01:22

Sutures of the Skull

7.5K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Summary

Orbital arteriovenous malformations (AVMs) are rare vascular lesions. This case highlights bony hyperostosis, an unusual skeletal change associated with orbital AVMs, emphasizing the need for comprehensive evaluation.

Area of Science:

  • Ophthalmology
  • Vascular Surgery
  • Radiology
  • Pathology

Background:

  • Orbital masses can present with varied etiologies, including vascular lesions.
  • Proptosis and orbital lesions require thorough diagnostic workup, including advanced imaging.
  • Vascular malformations can rarely involve skeletal structures.

Purpose of the Study:

  • To report a rare case of orbital arteriovenous malformation (AVM) with associated bony hyperostosis.
  • To discuss the diagnostic and surgical challenges of orbital vascular lesions.
  • To highlight the infrequent association between orbital vascular malformations and skeletal changes.

Main Methods:

  • Clinical presentation of a patient with a slowly enlarging orbital mass and proptosis.
  • Diagnostic imaging including MRI/CT to characterize the soft tissue lesion and bony changes.
  • Surgical debulking of the orbital lesion and hyperostotic bone.
  • Histopathologic analysis of the resected tissue to confirm vascular malformation and periosteal infiltration.

Main Results:

  • A previously healthy male presented with proptosis due to an orbital mass.
  • Imaging revealed a contrast-enhancing soft tissue lesion with associated bony hyperostosis.
  • Intraoperative findings confirmed significant arterial bleeding, consistent with an arteriovenous malformation.
  • Histopathology showed a vascular malformation infiltrating the periosteum with enhanced microvasculature.

Conclusions:

  • Orbital arteriovenous malformations are uncommon and can present with unusual features.
  • Bony hyperostosis is a rare manifestation of orbital vascular malformations.
  • Accurate diagnosis and surgical management are crucial for these complex orbital lesions.
