“…4,8 A report of an orbital and palpebral arteriovenous malformation was described in a patient with MAS; 32 however, vascular anomalies are not associated features of MAS. There are several reports of aneurysmal bone cysts forming in the setting of fibrous dysplasia; 10,21 however, the imaging and angiographic appearance in this case was not that of an aneurysmal bone cyst. GPS is a rare inherited bleeding disorder characterized by thrombocytopenia and an absence of platelet agranules, resulting in typical gray platelets on peripheral smears.…”

A 13-year-old boy with meningiomatosis, McCune-Albright syndrome, and gray platelet syndrome presented with an enlarging “lump” on his right forehead. A head CT scan revealed a polyostotic fibrous dysplasia involving the entire skull. A 3.4-cm right frontal osseous cavity and an overlying right forehead subcutaneous soft-tissue mass were seen, measuring 5.2 cm in diameter and 1.6 cm thick. Ultrasound of the cavity and overlying mass showed swirling of blood and an arterialized waveform. MRI revealed an en plaque meningioma underlying the cavity. An intraosseous pseudoaneurysm fed by 3 distal anterior division branches of the right middle meningeal artery (MMA) with contrast extravasation was found on angiography. Two MMA feeders were embolized with Onyx, with anterograde filling of the intraosseous cavity with Onyx. A small pocket of residual intracavity contrast filling postembolization from a smaller third MMA feeder eventually thrombosed and the forehead lump regressed.

“…The cystic degeneration of an FD causing rapid enlargement of FD lesions was documented by ClausHermberg et al occurring in a 15-year old patient in 2011 [19]. In a literature review, Haddad et al reported 6 cases of concomitant FDs and ABCs of the skull, and described their association as ''exceedingly rare'' [18]. No reports were found of FDs arising from ABCs.…”

“…Despite the unclear relationship between these two entities, the literature describes the development of an ABC (or a malignant lesion outbreak) from a previous FD, or the coexistence of both conditions at the same time [15][16][17][18]. The cystic degeneration of an FD causing rapid enlargement of FD lesions was documented by ClausHermberg et al occurring in a 15-year old patient in 2011 [19].…”

Aneurysmal bone cyst (ABC) is an uncommon, non-neoplastic, expansive and erosive bone lesion. Considered as a pseudocyst due the lack of epithelial lining, the presence of giant cells and similarity to other lesions can make preoperative diagnosis difficult; biopsy findings must be co-related to complete clinical and radiological assessment. ABC's controversial etiopathogenesis and variable clinicopathological presentations have been widely described, but to date, there are just a few reports in literature describing the development of fibrous dysplasia (FD) from an ABC, and even less cases occurring in the jaws. We describe the case of an ABC in an 8 year-old male patient, affecting the body of the mandible, which showed accelerated growth associated to thinning of the buccal, lingual and lower cortical plates. The treatment consisted of repetitive surgical resection, curettage of the lesion and mandibular reinforcement with osteosynthesis reconstruction plates. A 16-month follow-up showed selflimitation of the overgrowth. The final histopathological and radiological analysis confirmed the FD diagnosis.

“…In addition, large studies that may have included some pediatric patients had not published their detailed results based on age groups, [5][6][7] and the current literature is mainly limited to published case reports. [9][10][11][12][13][14] There are only 2 case reports describing the presence of fluid-fluid level in LCH. 12,14 In both of these cases, the FFL was demonstrated on both CT and MR imaging.…”

“…Trauma, benign lesions of the skeleton (eg, chondroblastoma, chondromyxoid fibroma, osteoblastoma, giant cell tumor, fibrous dysplasia), and even some malignant tumors (eg, osteosarcoma, chondrosarcoma, hemangioendothelioma) have been associated with development of aneurysmal bone cysts. 10,17,23 In the setting of fibrous dysplasia, secondary ABC formation can occur in addition to the more common evolving fibrous dysplasia with lytic areas or cystic degeneration. 24 Cephalohematoma is a subperiosteal hemorrhage that results from tearing of delicate vessels that traverse through the bone into the scalp.…”

SUMMARY:Fluid-fluid levels can occur whenever different fluid densities are contained within a cystic or compartmentalized lesion, usually related to the evolution of hematoma or necrosis. Review of the literature demonstrated that throughout the skeletal system, the most common etiology for fluid-fluid levels is aneurysmal bone cyst, but there are no dedicated studies of the pediatric calvaria, to our knowledge. In this report, we present clinicopathologic characteristics and CT and MR imaging of 11 patients with pediatric skull mass lesions demonstrating fluid-fluid levels. MR imaging demonstrated more fluid-fluid levels compared with CT in all cases. The etiologies of skull lesions with fluid-fluid levels were Langerhans cell histiocytosis in 4 (36.6%), aneurysmal bone cysts in 3 (27.2%), cephalohematoma in 3 (27.2%), and metastatic neuroblastoma in 1 (9%). Radiologists should be aware of the other etiologies of calvarial lesions with fluid-fluid levels in the pediatric skull.ABBREVIATIONS: ABC ϭ aneurysmal bone cyst; FFL ϭ fluid-fluid level; LCH ϭ Langerhans cell histiocytosis
