Aneurysmal bone cyst of the ethmoid sinus: A case report
Polish journal of radiology / Polish Medical Society of Radiology, 2010
Aneurysmal bone cyst is an expansile bone lesion, non-neoplastic in nature, occurring most commonly in long bones. It is uncommon in facial bones and exceptionally rare in ethmoid bone. Ten cases of aneurysmal bone cysts of ethmoid bone have been reported so far. A young adolescent presented with decreased vision and pain in the right eye. MRI revealed an expansile lesion having conspicuous fluid levels with a multiloculated appearance in the right ethmoid bone extending to the right orbit. CT was done to characterize better bone details. Both biopsy of the lesion and histopathology of resected specimen confirmed aneurysmal bone cyst. A characteristic appearance on MRI and CT examinations helped to confidently diagnose a relatively common lesion in an exceedingly rare location.
Paediatric aneurysmal bone cyst: not as easy as ABC
Journal of Surgical Case Reports
Aneurysmal bone cysts (ABCs) are expansile cystic lesions that can affect any bone of the body. Whilst these lesions are histologically benign, the lesions are locally aggressive and can affect the integrity of the affected bone as well as surrounding structures. ABCs arising in the head and neck region, particularly the paranasal sinuses are rare and they are limited to case reports in the literature. Due to the proximity of critical anatomical structures and the visual apparatus, the potential complications can be devastating. The present article discusses both the clinical and radiological findings of an ABC arising from the ethmoid sinuses in a 6-year-old child and the potentially challenging diagnosis with its complex ensuing surgical management. The identification of an ABC arising in the paranasal sinuses is both a diagnostic and surgical challenge and ideally requires complex management in a joint paediatric ENT and craniofacial unit.

An aneurysmal bone cyst (ABC) typically involves the long bones of the extremities, thorax, pelvis, or vertebrae. Skull base involvement is rare. We describe the case of a 9-year-old girl with ABC of the skull base. The patient had presented with nasal obstruction and headache over a period of approximately 8 months. The patient had no history of trauma or surgery. Physical and neurological examination findings normal. Magnetic resonance imaging (MRI) showed a multicystic lesion arising from the sphenoid sinus and extending into ethmoid sinus, superior nasal cavity and medial walls of the orbit. The lesion contained thin internal septations that revealed high signal characteristics on all sequences. The lesion was resected via an extended frontal approach without any complications. Histological evaluation confirmed that the lesion was an ABC. The patient did not receive postoperative radiotherapy. No recurrence was observed after 22 months. ABC should be considered in the differential diagnosis of bone neoplasms in this region.
Aneurysmal bone cyst of the ethmoid on fibrous dysplasia: A usual association within a rare location
Radiology Case Reports, 2019
Aneurysmal bone cyst is a non-neoplastic lesion consisting of blood filled sinusoidal spaces that expand from the affected bone. The most common locations of aneurysmal bone cysts are the metaphysis of long bones, followed by flat bones. Only 2% of all are found in the head and neck area, with mandible and maxilla being the most frequent sites involved, involvement of the ethmoidal bone is extremely rare. Their occurrence on a pre-existing bone lesion is described. Imaging features may assist in diagnosis by demonstrating blood-fluid levels, which are a characteristic finding in these lesions. We present computed tomography and magnetic resonance imaging findings of aneurysmal bone cyst of the ethmoid sinus on fibrous dysplasia in a 12-year-old female.
A Giant Aneurysmal Bone Cyst in the Sinonasal Area of a 7-year-old Girl
An aneurismal bone cyst (ABC) is a benign and blood-filled lesion of the bone which often originates from the spine and metaphysis of the long bones, particularly in the femur and tibia. [1] ABC can behave locally in an aggressive manner because of its rapid growth and osteolytic nature. The lesion can increase rapidly, resulting in weakening the affected bone, resulting in pathological fractures. [2] Approximately 2%-3% of cases of ABCs are found in the head-and-neck region, with the mandible being the most common site of occurrence. [3] Diagnosis of ABC is often challenging and confusing with other vascular or malignant lesions. Radiography often shows classic osteolytic lesions, where magnetic resonance imaging (MRI) articulates blood-filled spaces and fluid-fluid levels. [4] The mainstay of treatment of ABC is surgical intervention, including excision, curettage, and bone grafting. [5] ABCs are highly uncommon tumors in the head-and-neck region, particularly in children.

Objective: Aneurysmal bone cysts (ABCs) rarely involve the cranium. We report a case arising in the ethmoid sinus with orbital and intracranial invasion. Imaging suggested an associated fibro-osseous lesion. The lesion was completely resected. Histology confirmed the imaging diagnosis of ABC on top of an ossifying fibroma. A multi-disciplinary approach is essential for optimal surgical outcomes. Methods: We report a case of an 8-year-old boy with a 5 week history of painless, increasing prominence of the left eye. Clinical examination revealed non-pulsatile left proptosis. Visual acuity and ocular movements were normal. CT and MRI scans of the maxillofacial regions showed a large space-occupying lesion involving the left ethmoid air cells with left orbital and left inferior frontal intracranial extension. Multiple fluid levels with blood products were seen. Areas of the bony component of the lesion showed ground glass density on CT. Imaging was consistent with an aneurysmal bone cys...
Aneurysmal bone cyst of paranasal sinuses
Indian journal of otolaryngology and head and neck surgery : official publication of the Association of Otolaryngologists of India, 2002
Aneurysmal hone cyst is rare in paranasal sinuses. It may be uni or multilocutar It occurs alone or with other benign bone lesions. The exact pathogenesis of it is still unknown. The aggressiveness of the disease needs early diagnosis and proper management to prevent recurrence. This report describes a case of aneurysmal bone cyst involving the ethmoid and maxillary sinuses which was successfully managed.

Background: Aneurysmal bone cyst (ABC) is a benign intraosseous lesion characterized by blood-filled spaces of various sizes. These lesions are most commonly found in the long bones and spine but 2% occur in the jaws, more frequently in the mandible than in the maxilla (ratio 3:1). Case presentation: We present a case of an 8 year old boy with expansive ABC of left maxillary sinus which caused a deformity of the face. Conclusion: We discuss the current treatment and diagnostics options and describe successful treatment of our patient based on adequate surgical approach and complete removal of the lesion.
