AI Article Synopsis
- Choroidal metastasis is the most common type of malignant intraocular tumors, and this study aimed to analyze its structural and vascular characteristics using various imaging techniques.
- Sixteen patients with choroidal metastasis underwent multimodal imaging, including fluorescein angiography, EDI-OCT, and OCT angiography, revealing key features such as tumor location, thickness, and absence of intratumoral blood vessels.
- The findings indicated that imaging techniques provided valuable insights into choroidal metastasis, aiding in diagnosis and patient management.
Article Abstract
Background: Choroidal metastasis represents the most common malignant intraocular tumours.
Objectives: The objective of this study is to detect the structural and vascular features of choroidal metastasis by multimodal imaging.
Methods: Sixteen eyes of 16 patients with choroidal metastasis were enrolled in this prospective study. The multimodal imaging was performed in all patients: fluorescein angiography, indocyanine green angiography, enhanced depth imaging optical coherence tomography (EDI-OCT), OCT angiography (OCTA), and ultrasonography.
Results: The choroidal metastasis was located in the macula region in 9 eyes (57%) and in the extramacular region in 7 eyes (43%). EDI-OCT showed a mean thickness of 950 ± 246 µm, a smooth anterior tumour surface in 5 eyes (31%), and a lumpy bumpy appearance in 11 eyes (69%). The most frequent EDI-OCT features were represented by choriocapillaris thinning (100%), shaggy photoreceptors (82%), subretinal fluid with speckles (69%), subretinal lipofuscin pigment (6%), absence of drusen (100%), optical shadowing (94%), low-internal optical reflectivity (75%), and retinal pigment epithelium alterations (43%). OCTA revealed an absence of intratumoral vascular network in all cases.
Conclusions: The multimodal imaging contributed to greater insights into the anatomical and vascular features of choroidal metastasis. It allows for the collection of useful information to establish an appropriate diagnosis and follow-up.

Because of its benign nature and rarity, circumscribed choroidal hemangioma (CCH) often receives limited attention, leading to a high rate of misdiagnosis and a lack of standardized treatment protocols. We provide a thorough clarification of the demographics, clinical features, diagnosis, management, and prognosis of CCH. We conducted a systematic search of the PubMed, EMBASE, and Ovid databases up to December, 2023, to identify relevant studies.

Purpose: To present the case of a young patient with BRAF V600E-mutant cutaneous melanoma who developed bilateral choroidal metastases complicated by neovascular glaucoma (NVG) in both eyes following the interruption of nivolumab therapy.
Methods: A 28-year-old female with primary cutaneous melanoma of the left hand underwent surgical resection and adjuvant nivolumab. Immunotherapy was discontinued due to immune-related acute interstitial nephritis.

Department of Neuroradiology, University Hospital Würzburg, D-97080 Würzburg, Germany.
Background: Intracranial choroid plexus tumors (CPT) are rare and primarily affect young children. Leptomeningeal dissemination (LMD) has been reported not only in high-grade choroid plexus carcinoma (CPC) but also in lower histological grades; however, a systematic evaluation of CPT-specific imaging characteristics remains lacking.
Methods: We analyzed the imaging characteristics of LMD in a single-center pediatric cohort of 22 CPT patients (thirteen choroid plexus papilloma (CPP), six atypical choroid plexus papilloma (aCPP), three CPC), comparing LMD features with those of the primary tumor.

An 8-year-old girl with refractory high-risk neuroblastoma underwent 68Ga-DOTATATE PET/CT to evaluate the feasibility of potential 177Lu-DOTATATE therapy. The scan showed multiple foci of abnormal 68Ga-DOTATATE accumulation in the bone region, indicating the presence of bone metastases. Unexpectedly, an abnormal tracer uptake was noted in the left lateral ventricle area.
