Summary
Aneurysmal bone cysts (ABC) are rare, benign lesions. This case highlights an atypical ethmoid bone ABC in a young female, emphasizing its extensive involvement and unusual location.
Area of Science:
- Orthopedic Surgery
- Radiology
- Otolaryngology
Background:
- Aneurysmal bone cysts (ABC) are benign, slow-growing expansile bone lesions.
- Typically, ABCs occur in long bones or vertebrae.
- Ethmoid bone involvement is exceptionally rare, with only five prior reported cases.
Observation:
- This report details an unusual case of an aneurysmal bone cyst affecting the ethmoid bone.
- The patient was a 15-year-old female with extensive lesion involvement.
- The location and extent were considered atypical for this condition.
Findings:
- Plain radiographs lack specificity for diagnosing ABC.
- CT and MRI are crucial for delineating lesion extent.
- The presence of characteristic blood-fluid levels on imaging is a key diagnostic indicator for ABC.
Implications:
- This case expands the understanding of ABC presentation.
- Highlights the importance of advanced imaging (CT/MRI) in diagnosing rare bone lesions.
- Underscores the need for considering ABC in the differential diagnosis of ethmoid bone masses.

01:27Cranial Bones: Lateral View
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...

01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:14Cranial Bones: Superior and Posterior View
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,...

01:26Brain Abscess l: Introduction
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 infections,...
01:26Bone Markings
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...

01:29Bone Formation by Intramembranous Ossification
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...
