We present a case of an adult patient experiencing progressive visual loss. An initial presentation was concerning for neuromyelitis optica with optic chiasm involvement. However, persistent contrast enhancement observed in follow-up brain and orbit images raised suspicion for optic tract malignant neoplasm. Histopathological evolution of optic nerve biopsy confirmed the diagnosis of an optic chiasm glioma. The patient was then referred to oncology for chemotherapy.

Introduction: Tumorous growths in the sellar region pose significant clinical challenges due to their proximity to critical visual structures such as the optic chiasm and optic nerves. Given their proximity to the optic system, these tumors are often diagnosed due to a progressive decrease in visual acuity. Thus, surgical intervention is crucial to prevent irreversible damage, as timely decompression can halt the progression of edema and subsequent optic atrophy.

Background And Objective: Structured reports in radiology have demonstrated substantial advantages over unstructured ones. However, the transition from unstructured to structured reporting can face challenges, as experienced radiologists worry about the potential loss of valuable information. In this study, we fine-tuned the Llama 2 model capable of generating structured pituitary MRI reports from unstructured reports.

Objective: Patients with sellar lesions compressing the optic nerve sometimes perceive visual improvement after lesion resection, despite the absence of visual impairment on preoperative ophthalmological examination. This study investigated the indicators of latent visual impairment in patients with sellar lesions.
Methods: Forty-five patients who underwent surgery for sellar lesions compressing the optic nerve with no preoperative visual abnormalities and no change in visual assessment between pre- and postoperative ophthalmological examinations were divided into two groups: 1) patients who perceived recovery of visual function after lesion resection (the improved group), and 2) patients who did not (the unaffected group).

Papillary craniopharyngiomas are rare tumors prevalent to the precision oncology world due to their high rate of BRAF V600E mutations. Symptoms include vision loss, neuroendocrine dysfunction, and cognitive dysfunction. Treatment involves an interdisciplinary approach with surgery, radiation, and systemic treatment.

Pediatric intracranial epidermoid tumors are rare, slow-growing benign cystic lesions primarily originating from the ectodermal cell line during human embryogenesis. Intraparenchymal epidermoid tumors typically present with headaches, seizures, and focal neurological deficits. Although CT of the brain may show non-specific findings, MRI studies are more reliable and have a high confidence value in diagnosing intracranial epidermoid cystic lesions.
