Orbital compartment syndrome secondary to subperiosteal abscess initiated by barotrauma.

BMJ Case Rep 2022 Mar 24;15(3). Epub 2022 Mar 24.

Oral Maxillofacial Surgery, Auckland District Health Board, Auckland, New Zealand

This case report demonstrates an unusual complication of bacterial rhinosinusitis, causing orbital compartment syndrome from a presumed barotrauma. We postulate that the patient developed unilateral optic neuropathy, as a result of orbital compartment syndrome, secondary to orbital subperiosteal abscess following direct communication with the ethmoid sinus initiated by barotrauma. It is supported by evidence of a bony dehiscence on the lamina papyracea of the medial orbital wall with sudden onset of pain, proptosis and visual symptoms during flight. Read More

Imaging Findings of Pediatric Orbital Masses and Tumor Mimics.

Radiographics 2022 May-Jun;42(3):880-897. Epub 2022 Mar 4.

From the Departments of Radiology (A.K.J., J.B.G., L.J.E., G.B.L., J.C.B., W.B., V.M.S.), Ophthalmology (L.A.D.), Neurology (G.F.K.), Neurosurgery (W.B.), and Radiation Oncology (N.N.L.), Mayo Clinic, 200 1st St SW, Rochester, MN 55905.

Pediatric orbital masses are not common but encompass a wide spectrum of benign and malignant entities that range from developmental anomalies to primary and secondary orbital malignancies and metastatic disease. Certain orbital tumors are unique to pediatric patients, such as retinoblastoma and neuroblastoma. Clinical symptoms and signs are often insufficient to differentiate between orbital lesions, and imaging is essential for narrowing the diagnostic considerations and determining the most appropriate management strategy.
