“…A typical CT scan of a CG shows a lesion that is noncalcifying, with a smooth outline, rounded in shape, isodense with brain, and located in the superolateral bony orbit with an extraconal soft tissue mass, leading to inferior and anterior displacement of the globe 7. A CT scan provides an opportunity to evaluate the extension of the intraosseous portion of CG.…”

Two patients presented with cholesterol granuloma (CG), with completely different patterns of orbital roof involvement. One patient had a large intraorbital cystic CG, whereas the other had a very large intraosseous CG of the frontal bone. The presentation of CG with variable orbital roof involvement highlights the importance of being aware of the clinical characteristics and the imaging features of CG.

“…The CT findings are characterized by a well-defined, bi-convex, hyperdense, non enhancing mass located in the upper part of the orbit. On MRI, the hematoma can be seen as a well-defined mass with varying signal intensities depending on the age of the blood [32].…”

Spontaneous intracranial extradural haematoma associated with frontal sinusitis and orbital involvement

et al. 2011

Intracranial extradural hematoma is usually traumatic. Rarely, it can occur spontaneously associated with coagulative disorders (spontaneous or iatrogenic), dural vascular malformation, cranio-facial tumors and infections. In these cases, spontaneous extradural hematoma (SEH) is a serious event that needs to be recognized and managed in time to avoid fatal outcome. The authors report a case of a 12-year-old young girl with a 3-year history of right frontal sinusitis treated urgently for a right frontal extradural hematoma involving the orbit. Diagnosis and management of this case is discussed reviewing the pertinent literature.

“…Spontaneous orbital subperiosteal hematoma may have peculiar clinical characteristics. 1,2,12) A case of spontaneous orbital hematoma confined within the lateral rectus muscle resolved spontaneously without medication, suggesting that serial MR imaging follow up would be sufficient for patients with spontaneous intramuscular hemorrhage in the extraocular muscle. 9) The present retrobulbar hematoma was mostly confined within the muscle cone, without continuity with the periosteum surrounding the orbital contents.…”

A 75-year-old male suffered sudden onset of retroorbital pain, visual loss, periorbital ecchymosis, and double vision without preceding trauma, paranasal sinus surgery, or infectious signs. Neuroophthalmological inspection also revealed marked restriction of the extraocular movements, visual defect, and exophthalmos on the affected side. Neuroimaging showed an irregular-shaped retrobulbar mass centered in the inferolateral aspect and partially protruding between the inferior and lateral rectus muscles without enhancement by contrast medium. High dose steroid therapy provided little improvement in the visual symptoms. Needle aspiration biopsy revealed only fluid hematoma. Surgical exploration via the lateral wall of the orbit resulted in escape of chocolate-colored, liquefied hematoma during dissection between the inferior and lateral rectus muscles. No obvious vascular lesion was recognized. A small purplish elastic soft mass with irregular contours was recognized adherent to the inferior rectus muscle within the capsule of the hematoma. The mass was subtotally resected. The histological diagnosis was inflammatory pseudotumor with hemorrhagic change. No component of vascular malformation was found. Visual function and extraocular movement improved postoperatively and neuroimaging showed no abnormal structures in the affected orbit. Pseudotumor may bleed and form a retrobulbar hematoma which carries the risk of visual loss.
