title: Acute adduction deficit in a 7-week-old infant.
abstract: A 7-week-old infant with sudden onset adduction deficit and proptosis is reported. The main differential diagnoses included orbital myositis, orbital cellulitis, capillary haemangioma and rhabdomyosarcoma. A CT scan revealed a postseptal cellulitis-like picture with thickening of the medial rectus muscle. He was given a course of antibiotics, withholding steroids and biopsy. His condition resolved completely on high-dose antibiotics alone. To our knowledge this is the youngest patient with infectious orbital myositis and postseptal cellulitis described in the literature. The clinical course emphasizes the importance of administering sufficiently high doses of antibiotics.
