Cranial aneurysmal bone cysts presenting with raised intracranial pressure: report of two cases

Abstract

Aneurysmal bone cysts in the skull vault are reported in two patients 7 and 9 years old, who presented with vomiting and headaches caused by raised intracranial pressure. CT showed the cystic lesion in the diploë, with predominantly inward expansion. Fluid-fluid levels were seen on both CT and MRI; the latter also showed bleeding within the cyst. MR angiography showed compression of the superior sagittal sinus in the second case.

Pediatric Idiopathic Intracranial Hypertension (Pseudotumor Cerebri)

“…The diagnosis of IIH in children is one of exclusion, as central nervous system neoplasms may present with similar symptoms [56,57,58,59]. Nonthrobbing, intermittent headaches that occur upon awakening [57], behavior changes, seizures, and focal neurologic deficits are more likely seen in children with brain neoplasms as compared to those with IIH [56,58].…”

Intracranial, intradural aneurysmal bone cyst

“…Although ABCs have no malignant or metastatic potential, local mass effect and alteration of locoregional vascularity may be severe, necessitating treatment [12][13][14]. Options include percutaneous injection with sclerosant, embolic therapy, radiation therapy, and surgical resection, and complications include profuse bleeding and recurrence [15].…”

Giant pediatric aneurysmal bone cyst of the occipital bone: Case report and review of the literature

“…Only 16 cases of occipital aneurysmal bone cysts were described in the literature and the gender distribution was equal and the median age was 15 years [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] [ Table 1]. The precise origin of ABCs remains uncertain, but most authors feel that ABCs are a reactive process secondary to trauma or a vascular disturbance.…”

“…Only two cases of such aneurysms presenting with pure SAH have been reported. [1][2][3][4]8] These aneurysms may either be sacular or fusiform. [1][2][3][4]8] These aneurysms may either be sacular or fusiform.…”
