Idiopathic orbital inflammation, also known as orbital pseudotumor, describes a spectrum of idiopathic, non-neoplastic, non-infectious, space-occupying orbital lesions without identifiable local or systemic cause. The condition occurs mainly in young adults who may present with acute pain, proptosis, chemosis and limitations of extraocular movements. Decreased vision due to optic nerve infiltration and macular edema as a result of scleritis is less common sequel of orbital pseudotumor. Herein, we present a case of unilateral orbital pseudotumor in a young male who presented with chief complaints of painful decreased vision which was attributed to optic neuritis and macular edema as a result of scleritis. Imaging studies were helpful in the establishment of the correct diagnosis and patient's complaints improved with administration of systemic corticosteroids.

The most common diagnostic error of IIH is inaccurate funduscopic examination. Moreover, IIH could be diagnosed without papilledema. Trans orbital sonography could be used as a non-invasive and cheap tool for discovering increased ICP (intracranial Pressure).

Material And Methods: The study included 24 patients (8 men and 16 women) with diffuse orbital tissue involvement in GPA. Group 1 (active stage) included nine patients, while group 2 (inactive stage) consisted of 18 patients.

Objectives: To evaluate the value of deep-learning-based intratumoral and peritumoral features for differentiating ocular adnexal lymphoma (OAL) and idiopathic orbital inflammation (IOI).
Methods: Nighty-seven patients with histopathologically confirmed OAL (n = 43) and IOI (n = 54) were randomly divided into training (n = 79) and test (n = 18) groups. DL-based intratumoral and peritumoral features were extracted to characterize the differences in heterogeneity and tissue invasion between different lesions, respectively.

Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated disease with many important manifestations in hematopoietic and lymphoid tissue. IgG4 is the least naturally abundant IgG subclass, and the hallmark feature of IgG4-RD is markedly increased IgG4-positive plasma cells (with an IgG4 to IgG ratio >40%) in affected tissue, along with elevated polyclonal serum IgG and IgG4 in most patients. Histological diagnosis is essential, and other key features include storiform fibrosis, lymphoplasmacytic infiltrate, tissue eosinophilia, and obliterative phlebitis.

Article Synopsis
- - A 22-year-old male experienced progressive swelling and vision loss in his right eye over a month, but displayed no systemic symptoms that would indicate an infection or illness.
- - Imaging suggested benign conditions, but blood tests revealed hematological issues that led to a bone marrow biopsy, confirming acute myeloid leukemia (AML) with a favorable genetic marker.
- - After starting chemotherapy, the patient showed significant improvement in his eye symptoms and vision, highlighting the need for awareness of potential blood cancers in young patients with unexplained eye issues.
