A 23-year male with complaint of diminution of vision in left eye was referred to us as a suspect case of inflammatory choroidal mass/melanoma. Examination revealed a total retinal detachment with a reddish brown lesion in the superior hemi-fundus. B-scan ultrasonography demonstrated the 'mass' to be intra-retinal without choroidal involvement. A diagnosis of haemorrhagic intraretinal macrocyst (HIM) was made. We report this case to highlight the importance of correctly diagnosing an HIM and utilizing ultrasound to rule out choroidal pathologies, especially melanoma. This is essential as the management and prognosis of the two disorders is entirely different.
