case_images: Image of ultrasonography of the right eye. Hyperechogenic focus measuring 12.68 x 13.98 mm filling most of the intrabulbar cavity.

case_images: Because of this suspect find, we proceeded with ultrasonography of the right eye and found the hyperechogenic focus measuring 13.68 x 12.98 mm, filling a substantial part of the vitreous cavity (shown in Fig. 1).
case_images: Image of MRI showing tumour grow in ciliary body of right eye measuring 17 x 10 mm without extrascleral extension. Arrow pointing to tumour mass.

case_images: In T2-weighted images appeared as hypointense4 and in T1-weighted images appeared as isointense (shown in Fig. 2).
case_images: Image of positron emission tomography with computed tomography with metabolically active tumour lesion in right eye with increased accumulation of 18FDG. Arrow pointing to metabolically active tumour lesion. 18FDG, 8F-fluoro-2-deoxy-D-glucose.

case_images: Conclusion of positron emission tomography with computed tomography established metabolic active intraocular tumour growth in the right eye, classified as primary tumour, as there was no pathologically increased accumulation of 8F-fluoro-2-deoxy-D-glucose in the scans, concluded as without the nature of possible dissemination of underlying disease (shown in Fig. 3).
case_images: Leiomyoma of the ciliary body of the right eye. The tumour is formed of spindle cells (*) with fine fibrillar, sometimes vacuolated, eosinophilic cytoplasm, with partial coverage by pigmented epithelium (arrow). The tumour tissue shows expression of muscle markers - smooth muscle actin, caldesmon, desmin, neuronal markers - CD56, and neuron-specific enolase, proliferation activity (Ki-67) is low (arrowhead). Upper block: Hematoxylin and eosin, x100; lower block, x200. SMA, smooth muscle actin; NSE, neuron-specific enolase; HE, hematoxylin and eosin.

case_images: HS actin, S100-, GFAP-, CD57-, melan-A-, Ki67+ <1%, calponin+, desmin+, CD56+, neuron-specific enolase+. Histopathological analysis closed the matter as leiomyoma of the ciliary body likely of mesectodermal origin due to positivity of CD56 and neuron-specific enolase, shown in Figure 4.
