IgG4-related disease is a newly described systemic autoimmune and allergic disease, characterized histologically by a fibroinflammatory response with IgG4 plasma cells. It was initially described as affecting the pancreas, but commonly involves the head and neck region as well. While a biopsy is essential for definitive diagnosis, cross sectional imaging may be the initial modality which may suggest this entity. We describe a case of pathologically proven IgG4 related disease which highlights some key radiologic features seen in this entity. Our case highlights some key radiological features of IgG4- related disease in the head and neck, with involvement of the lacrimal glands, pituitary gland and cranial nerves on CT.
Acute sinusitis is most often a mild self-limiting disease. However, it may progress into severe and life threatening complications. One of the commonest being orbital complication of which visual loss is a direct consequence. In this 10 year retrospective study, the nature of orbital complication, clinical presentation and treatment modalities and outcome seen in children with acute sinusitis in a tertiary referral institute were reviewed. Of six patients, there was a case of preseptal cellulitis, 4 cases of subperiosteal abscess and one case of orbital abscess. Periorbital swelling was a common presenting feature. In 5 cases this was associated with proptosis with one case of impending optic nerve compression. The value of computed tomography and opthalmological examination as a component in the management plan is highlighted. All patients were treated with intravenous antibiotics but evidence of abscess collection warranted urgent surgical drainage in 5 patients, 3 being endoscopic drainage while external approach was done for the remaining 2 patients. Thus a child exhibiting orbital complication of acute sinusitis, prompt diagnosis and treatment is essential in obtaining the best outcome for the child.
Objective: Subperiosteal orbital abscesses (SPOAs) secondary to acute sinusitis are rare occurrences in the pediatric age group, more so in the neonatal period. Here, a rare case of SPOA in a 38-day-old newborn later drained via endoscopic sinus surgery is included also. This review describes the demographic data, clinical history, treatment, microbiology results, complications, and outcome.
Methods: The admission records for all the patients who were admitted to the Pediatric Surgical Ward in Sarawak General Hospital, Kuching, Malaysia, between January 2004 and May 2009 were retrospectively reviewed. Records of patients who presented with preseptal cellulitis, orbital cellulitis, subperiosteal abscess (extraconal), orbital abscess (intraconal), and cavernous sinus thrombosis were closely studied. Ophthalmology consultations were obtained in all these cases. Ultimately, 3 patients having SPOA secondary to acute sinusitis were selected for this review.
Results: All patients were male with rapid onset of periorbital signs, absence of purulent rhinorrhea, and presence of significant thrombocytosis (exceeding 500 × 109/L). The 38-day-old newborn had mixed infection of methicillin-resistant coagulase-negative Staphylococcus bacteremia and local Acinetobacter eye infection with Staphylococcus aureus in the SPOA. All had medially located SPOA that was adequately drained via endoscopic sinus surgery, resulting in full recovery.
Conclusion: Newborns with preexisting risk factors and immature immunity are at risk of severe and rare infections. Contrast-enhanced paranasal sinus computed tomographic scan is mandatory and reliable to differentiate preseptal and postseptal orbital infection, as both conditions can present similarly and rapidly deteriorate. In the contrast-enhanced computed tomography–demonstrable SPOA, endoscopic sinus surgery drainage of the abscess proved to be safe and reliable as the main treatment modality. All patients recovered well without complications.
Lacrimal gland involvement in granulomatosis with polyangiitis (GPA) commonly accompanies orbital disease, but occasionally may be the sole presentation preceding any other organ manifestation or systemic disease. Diagnosis of orbital GPA, especially in patients with lacrimal involvement as the initial presentation, can be difficult because of nonspecific clinical features and lack of diagnostic specificity on histologic and antineutrophilic cytoplasmic antibody (ANCA) testing. Orbital GPA can be associated with a high morbidity from potential visual loss or rapid progression of latent systemic disease, making early diagnosis important. The purpose of this study was to describe the clinical and imaging features of patients with lacrimal gland involvement secondary to GPA and to compare them with those of other orbital inflammatory conditions in the lacrimal gland fossa.
