RESUMO
Orbital cellulitis describes an infection involving the soft tissues posterior to the orbital septum including the fat and muscle within the bony orbit. This condition is associated with severe sight and life-threatening complications. Distinguishing it from preseptal cellulitis is difficult, but important. Acute sinusitis is the commonest predisposing factor. Clinical findings alone are not specific enough to distinguish between preseptal and post septal orbital cellulitis. Early diagnosis using CT orbit is important to rule out complications such as orbital cellulitis, subperiosteal abscess. The most common location of subperiosteal abscess is the medial wall of the orbit. Transnasal endoscopic drainage of the abscess is a functional and minimally invasive technique and is the treatment of choice at present. Early diagnosis and intervention are mandatory to prevent the visual loss and life-threatening complication.Here, the authors describe a 2 months old infant with orbital cellulitis and medial subperiosteal abscess and treated with transnasal endoscopic drainage of the subperiosteal abscess.
RESUMO
Periorbital swelling is a rather common symptom. Of the causes, the associated lymphoproliferative diseases rarely involve, and, if any, pseudolymphoma and B-cell type of lymphoma are mostly implicated. We report herein a case of unspecified peripheral T-cell lymphoma presenting as only manifestation of bilateral orbital swelling. A 32-year-old woman had a fluctuant course of bilateral mild erythematous swelling without ocular or lymph node involvement for about 2 years. Biopsy specimens from the left upper eyelid showed infiltration of medium-sized atypical cells with pleomorphism, convoluted nuclei, scant cytoplasm and less prominent nuclei. The cell was LCA, UCHL-1 and CD3 positive, but negative for L26. She received six cycles of CHOP combined therapy, with a marked improvement. No relapse was noted during a period of about a 6-month follow-up.
