“…ABC may occur at any segment of the spine and has different imaging characteristics at different stages and locations. Radiographic manifestations such as lytic bone destruction, thin layer ossification, bone surface roughness, bone ridge and bone separation can be detected by X-ray ( 12 , 13 ). As the lesion progresses, vertebral segments, including the vertebral arch and transverse process are damaged and become thinner, compressed and displaced, which may easily lead to pathological fracture ( 14 ).…”

The current study aimed to investigate the imaging manifestations of vertebral aneurysmal bone cyst (ABC), and examine the clinical value of interventional embolization. Imaging examinations of 5 patients with pathologically confirmed spinal ABC were analysed and arterial angiography and embolization were performed prior to surgery. The cases in this cohort exhibited different degrees of intrusion into the vertebral arch and spinous and transverse processes. Lesions that protruded into the spinal canal resulted in compression of the thecal sac and spinal cord. Enlargement of arteries was detected by digital subtraction angiography and decreased significantly following embolization. Blood loss during surgery was also significantly reduced. Preoperative embolization of ABC reduces bleeding and allows for easy access to tissue, which is of great clinical value.

“…The blood supply in the spinal ABC is complex and involves multiple blood vessels ( 13 ). In general, the lesion is supplied by the intercostal artery and lumbar artery at the same level as the vertebra, but adjacent arteries may also be involved.…”

“…The differential diagnosis for an extra-axial cystic lesion with fluid-haematocrit levels includes subdural haemorrhage, cystic schwannoma, cystic meningioma, telangiectatic osteosarcoma of the skull and cystic metastasis. Rare possibilities like a dural aneurysmal bone cyst (ABC) and meningeal Ewing’s sarcoma were also considered 4–8…”

“…However, a multiseptated cystic lesion with fluid-haematocrit levels on imaging has not been described in the literature. Three documented case reports of an ABC involving the dura without affecting adjacent bone were found in the literature 4 5. One of the case reports showed a similar extra-axial lesion with haemorrhagic levels—so a dural ABC was our primary differential.…”

Intracranial extraosseous dural-based Ewing’s sarcoma with fluid-haematocrit levels: imaging findings of a rare tumour

et al. 2022

Extraosseous dural-based primary Ewing’s sarcoma of the central nervous system is a rare tumour posing a diagnostic challenge. On cross-sectional radiological imaging, the lesion has an extra-axial location with heterogeneous appearance. These lesions are usually multicystic with internal haemorrhage causing fluid-haematocrit levels. It mimics conditions like an aneurysmal bone cyst, microcystic meningioma, telangiectatic osteosarcoma or cystic metastasis. Exclusion of primary Ewing’s sarcoma or malignancy elsewhere in the body is required to rule out a secondary. Surgery along with adjuvant chemotherapy and focal radiotherapy is the preferred mode of treatment. Due to the presence of non-specific small round blue cells on H&E stain, these tumours are also confused with lymphoma, osteosarcoma, rhabdomyosarcoma, Merkel cell carcinoma, ependymoblastoma and neuroendocrine carcinoma. Immunohistochemistry provides a definitive diagnosis. A high degree of suspicion in the preoperative scans is crucial for prognostication and early management of this aggressive tumour leading to improved patient survival.
