Aneurysmal Bone Cyst of the Petrous Bone: Case Presentation and Review of the Literature

Abstract

Aneurysmal bone cysts (ABC) were originally described by Jaffe and Lichtenstein [Arch Surg 1942;44:1004–1025] in 1942 as nonneoplastic benign lesions with obscure pathogenesis. ABC occurring in the temporal bone are uncommon. Those arising from the petrous portion of the temporal bone are exceedingly rare. We report a right petrous ABC in a 16-year-old girl who presented clinically with hearing loss, facial weakness, and facial numbness and tingling. Her symptoms were preceded by a coincidental traumatic concussion 4 months earlier. Preoperative magnetic resonance imaging and computed tomography findings were both consistent with an ABC, although the lesion was noted to be in a very unusual location. Surgical resection was performed with adjuvant preoperative embolization. The patient recovered complete facial sensation and movement, and follow-up imaging documented complete resection.

Aneurysmal bone cyst of temporal bone

“…Gross pathological examination shows honeycomb-appearing cyst comprising multiple sinusoidal spaces filled with unclotted blood and blood-tinged serous fluid 13. Histologically, these honeycomb-like spaces lack endothelial linings and are filled with haemorrhagic fluid.…”

Altıncı kraniyal sinir felci oluşturan ve ölümle sonuçlanan petröz kemik yerleşimli anevrizmal kemik kisti

“…Recurrence of ABC of the calvaria is rare, whereas recurrence of ABC of other bones may be as high as 50% (4,10). Recurrence has been related to younger age, larger tumor, presence of mitosis, incomplete surgical removal and dural involvement.…”

Skull Base Aneurysmal Bone Cyst Presented with Foramen Jugular Syndrome and Multi-Osseous Involvement

“…Of all ABCs, about 2-6% occurs in the skull. The temporal bone, especially the petrous part, is an unusual site of involvement (1-3). In some cases, diagnosis of ABC is difficult because of similar radiologic and pathologic features to other benign and malignant tumors, especially when it occurs in an unusual site like the base of the skull.…”

“…This expansile bone lesion commonly involves the metaphysis of long tubular bones, posterior elements of the vertebrae and flat bones (1, 2). The skull base is an uncommon location for this tumor with a reported incidence of 3-6% (2, 3). We describe a 17-year-old man with ABC of the skull base which presented with cranial nerve involvement.…”
