We report a patient with infantile Alexander disease (AXD) due to the recurrent p.Arg79Cys GFAP mutation. In addition to typical AXD abnormalities, magnetic resonance imaging demonstrated a tumor-like lesion of the optic chiasm suggestive of a glioma. A transient papilloedema appeared during the follow-up and the lesion partially regressed despite a worsening of white matter involvement. Rare radiological and pathological tumor-like lesions have already been reported in AXD patients. This patient confirms that enlargement of the optic chiasm is a rare feature of AXD, possibly linked to abnormal astrocytic proliferation.

Purpose: We present a case of Kikuchi-Fujimoto Disease (KFD) associated with bilateral optic neuropathy progressing to vision loss.
Observations: A 17-year-old male was referred for bilateral optic nerve pallor. Eight years prior, he was diagnosed with KFD after workup for lymphadenopathy and treated with prednisolone acutely followed by long-term Plaquenil.

Background: Adamantinomatous craniopharyngiomas (ACPs) are slow-growing, cystic, highly morbid central nervous system tumors located adjacent to vital structures including the pituitary, hypothalamus, and optic chiasm. Tumor recurrence is common. Treatment relies on resection with or without adjuvant radiation and is highly individualized.

Introduction And Importance: Rhinocerebral mucormycosis (RM) is a rare and severe condition caused by filamentous fungi, characterized by infection of the nose, paranasal sinuses, and brain. It is the most common and fatal clinical form of mucormycosis, accounting for 50 % of reported cases. RM is seldom reported during the postpartum period.

Purpose: Diffusion magnetic resonance imaging (dMRI) quantitatively estimates brain microstructure, diffusion tractography being one clinically utilized framework. To advance such dMRI approaches, direct quantitative comparisons between microscale anisotropy and orientation are imperative. Complete backscattering Mueller matrix polarized light imaging (PLI) enables the imaging of thin and thick tissue specimens to acquire numerous optical metrics not possible through conventional transmission PLI methods.

Purpose: This study aims to investigate and compare High Dose Rate Brachytherapy (HDR-BT) with Helical Tomotherapy (HT) treatment plans. The focus is on small target volumes near radiation-sensitive organs in the ocular region, to evaluate the advantages of these techniques in treating skin cancer.
Methods: This retrospective observational analysis included patients who underwent skin cancer HDR-BT Freiburg flap treatment between 2019 and 2023.
