Aneurysmal bone cysts (ABCs) are rare benign bone lesions. This case highlights a rare skull ABC secondary to osteoblastoma in a child, successfully treated with surgery.
Area of Science:
- Neurosurgery
- Pediatric Oncology
- Orthopedic Surgery
Background:
- Aneurysmal bone cysts (ABCs) are rare, benign vascular bone lesions, predominantly affecting young individuals.
- While often primary, ABCs can arise secondary to other bone pathologies, including osteoblastomas.
- Skull ABCs are exceptionally uncommon and pose significant risks due to potential intracranial extension, leading to complications like hydrocephalus and hemorrhage.
Observation:
- A 9-year-old male presented with symptoms of headache, nausea, and vomiting, with no discernible neurological deficits.
- Radiological imaging revealed a characteristic 'soap-bubble' lesion in the right cerebellum, exerting mass effect.
- The lesion was surgically resected via a right sub-occipital craniotomy with wide marginal excision.
Findings:
- Histopathological examination confirmed the diagnosis of osteoblastoma with features of an aneurysmal bone cyst.
- The surgical intervention resulted in excellent patient outcomes.
Implications:
- This case underscores the importance of considering secondary aneurysmal bone cysts in pediatric patients with intracranial lesions.
- Early diagnosis and surgical management of skull ABCs are crucial for favorable outcomes.
- Further research into the pathogenesis and optimal treatment strategies for secondary ABCs is warranted.

Cranial Bones: Superior and Posterior View
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 Skull
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...
Overview of the Skull
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...
Cranial Bones: Lateral View
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...
Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...
