Summary
Aneurysmal bone cysts (ABCs) can occur in the nasal cavity, presenting with symptoms like headache and double vision. This elderly patient
Area of Science:
- Otorhinolaryngology
- Pathology
- Radiology
Background:
- Aneurysmal bone cysts (ABCs) are rare, benign, expansile bone lesions, typically occurring in long bones and the spine.
- Nasal cavity and paranasal sinus involvement by ABCs is exceptionally rare, posing diagnostic and management challenges.
Observation:
- A 90-year-old female presented with headache and diplopia, indicative of potential space-occupying lesions.
- Computed Tomography (CT) scan revealed a mass within the nasal cavity and paranasal sinuses.
- Direct examination identified the mass originating from the ethmoid, likely the nasal septum.
Findings:
- Histopathological analysis of biopsies confirmed the diagnosis of an aneurysmal bone cyst.
- The patient elected conservative management over surgical intervention.
- A follow-up CT scan after 4 years demonstrated significant enlargement of the aneurysmal bone cyst.
Implications:
- This case highlights the rare occurrence of aneurysmal bone cysts in the sinonasal region.
- Conservative management may be an option, but requires careful monitoring due to potential for significant growth.
- Further research is warranted to understand the behavior and optimal treatment strategies for sinonasal ABCs.

01:27Cranial Bones: Lateral View
6.8K
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...

01:26Brain Abscess l: Introduction
21
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial...

01:14Cranial Bones: Superior and Posterior View
7.6K
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,...

01:26Bone Markings
8.8K
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

01:08Overview of the Skull
12.2K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:29Bone Formation by Intramembranous Ossification
16.1K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...
