An 8-year-old male presented to the pediatric emergency department with subjective fever, blurry vision, and left eye pain. On physical examination, there was mild left lower lid erythema and a subtle left eye elevation deficit. Computed tomography demonstrated preseptal soft tissue swelling without orbital involvement; however, there was varying amounts of paranasal sinus opacification. Despite the negative scan, a diagnosis of orbital cellulitis associated with sinusitis was made and treatment with intravenous antibiotics was initiated. A magnetic resonance imaging performed subsequently revealed orbital fat stranding and inferior rectus enlargement and enhancement near the orbital apex, indicating the presence of orbital cellulitis. This case demonstrates the utility of magnetic resonance imaging when initial computed tomography imaging is negative in patients with concern for orbital cellulitis.

Langerhans cell histiocytosis (LCH) is a rare multi-system disease. It presents infrequently as a childhood orbital tumor, and can mimic more common inflammatory orbital disease processes. We report the clinical, histopathological, and electron microscopic findings of orbital LCH in an 18-month-old child, along with a review of the recent literature regarding molecular pathogenetic analysis of LCH. The child presented with a two-week history of progressive left periorbital edema and redness. He was initially diagnosed and treated empirically for bacterial periorbital cellulitis, but subsequently underwent ophthalmological consultation after he failed to improve. Histopathological examination of an orbital biopsy specimen revealed numerous Langerhans-type cells, which stain positive for CD1A and CD207 (langerin). Electron microscopic examination demonstrated characteristic Birbeck granules within the Langerhans-type cells. Three year follow-up did not demonstrate recurrence or disease progression.

- MMedicine (Baltimore) 2018; 97(19):e0706
- CONCLUSIONS: Penetrating transorbital injury complications may occur because of retained wooden foreign bodies near the intracranial arteries. Reasonable surgical intervention and special attention should be performed in this kind of trauma.

Visual loss can be the result of an abnormality anywhere along the visual pathway including the globe, optic nerve, optic chiasm, optic tract, thalamus, optic radiations or primary visual cortex. Appropriate imaging analysis of visual loss is facilitated by a compartmental approach that establishes a differential diagnosis on the basis of suspected lesion location and specific clinical features. CT and MRI are the primary imaging modalities used to evaluate patients with visual loss and are often complementary in evaluating these patients. One modality may be preferred over the other depending on the specific clinical scenario. Depending on the pattern of visual loss and differential diagnosis, imaging coverage may require targeted evaluation of the orbits and/or assessment of the brain. Contrast is preferred when masses and inflammatory processes are differential considerations. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Infections of the orbit and periorbita are relatively frequent, and can cause significant local and systemic morbidity. Loss of vision occurs in more than 10% of patients, and systemic sequelae can include meningitis, intracranial abscess, and death. Numerous organisms infect the orbit, but the most common are bacteria. There are many methods through which orbital infections occur, with infection from the neighboring ethmoid sinuses the most likely cause for all age groups. Prompt management is essential in suspected orbital cellulitis, and involves urgent intravenous antibiotics, rehydration, and treatment of any co-existent underlying systemic disease, e.g., diabetes, renal failure. This review summarizes the common infectious processes of the orbit in both pediatric and adult groups. We review pathophysiology, symptoms, signs, and treatment for infectious orbital processes.

We report a case of invasive fungal sinusitis caused by Scopulariopsis in 57 year-old man who had recurrence of orbital cellulitis. CT-scan and magnetic resonance imaging found an orbital cellulitis associated to a left frontal sinusitis with bone erosion and calcification. Patient was treated by surgical debridement and voriconazole. Culture of excised tissue was positive for Scopulariopsis.
- A case report of orbital Langerhans cell histiocytosis presenting as a orbital cellulitis. [Journal Article]
- ASArch Soc Esp Oftalmol 2018 Apr 08
- CONCLUSIONS: The orbital involvement of Langerhans cell histiocytosis, despite its low incidence, should be considered in the examination of acute peri-orbital swelling. It usually presents as an osteolytic lesion, and it is confirmed with a histological examination and immunohistochemical techniques for CD1a and S100. An interdisciplinary approach is recommended to rule out multifocal or multisystemic diseases, as well as to develop an appropriate treatment strategy.
- Lymphoma Maxilla mimicking orbital cellulitis; case report and review of Literature. [Journal Article]
- NJNepal J Ophthalmol 2017; 9(18):180-186
- CONCLUSIONS: The diagnosis of maxillary sinus lymphoma needs to be borne in mind when a clinician encounters a case of Orbital Cellulitis. It may be difficult to diagnose clinically and require radio-pathological correlation.
- Clostridium perfringens panophthalmitis and orbital cellulitis: a case report. [Case Reports]
- BOBMC Ophthalmol 2018 Apr 10; 18(1):88
- CONCLUSIONS: Clostridial endophthalmitis secondary to penetrating injuries is a fulminant infection, almost always resulting in loss of the globe in the case of advanced infection. When feasible, early vitrectomy and intravitreal antibiotics should be considered in patients with penetrating eye injuries with contaminated foreign bodies.
