Orbital Subperiosteal Hematoma Associated With Subfrontal Extradural Hematoma

Subperiosteal hematoma of the iliac bone: imaging features of acute and chronic stages with emphasis on pathophysiology

“…Pathophysiology Subperiosteal hematomas forming on flat bones have been reported in the calvarium [9], the orbit [10], and the iliac wing. The vast majority of these lesions occur in children and young adults, with no patient older than 18 years old for the reported cases of iliac hematoma [1][2][3][4][5][6][7][8].…”

“…Several points support this assumption. First, other lesions with a lensshaped appearance are known to result from effusion of blood into non-extendable areas, as seen in cephalhematomas, orbital subperiosteal hematomas, or even epidural hematomas [9,10]. Second, the progressive peripheral mineralization seen in two cases of acute hematoma, particularly the one with long-term follow-up, provides insight into the progression of the hematoma towards ossification and the appearance encountered in adults.…”

“…Further, the close proximity of these nerves to the superficial fascia of the iliacus muscle and additional laminae has been emphasized in anatomical studies [15,16]. The subperiosteal location of acute hematoma is strongly suggested by its lens-shaped appearance [9,10] with smooth edges, overlying the iliac bone and shifting the iliacus muscle medially. This semiological aspect requires further discussion as this distinction was not always made in similar cases in the literature.…”

Liver Disease Associated Subperiosteal Hematoma in a Postoperative Cataract Surgery Patient

“…Seigel et al reported 3 cases in 1982 describing young males ranging from 15-37 years old who developed these hematomas after trauma [5]. The trauma may be significant or minimal, as in a case reported by Sharma et al in 2007 in which a child developed a large hematoma after minimal brow trauma [5,6]. Presenting symptoms may include pain, edema, ecchymosis, proptosis, diplopia, and decreased vision, especially if there is optic nerve compression.…”

Concomitant occurrence of subfrontal extradural hematoma and orbital subperiosteal hematoma: A rare entity

“…Simultaneous occurrence of sub frontal extradural hematoma and orbital subperiosteal hematoma is extremely rare and only eight such cases have been reported. [1,[3][4][5][6][7][8][9] We report our experience with four such patients. …”
