1/3. Unusual presenting signs of retinoblastoma: a case study.

    In the US, leukocoria is the most common presenting sign of retinoblastoma, and strabismus is the second most common finding. retinoblastoma less frequently presents as an inflammatory process involving the eye or orbit, which often masks the symptoms of retinoblastoma. Children who present with leukocoria strabismus, hypopyon, heterochromia, rubeosis, hyphema, or an orbital cellulitis should be referred to an ophthalmologist for a dilated fundus examination of both eyes, under general anesthesia if necessary, to rule out the possibility of a retinoblastoma in the differential diagnosis.

2/3. Diffuse infiltrating retinoblastoma.

    A young child was examined for unilateral hyphema of 1 month duration with a questionable history of blunt trauma. ultrasonography was negative for tumefaction. Two months later the media cleared, revealing a diffusely abnormal retina. Computed tomography demonstrated a diffusely thickened posterior pole containing calcium. Histopathology of the enucleated globe was consistent with a diffuse infiltrating retinoblastoma. This is the first report of computed tomographic findings in diffuse infiltrating retinoblastoma.

3/3. retinoblastoma presenting as a total hyphema.

    retinoblastoma, the most common intraocular malignancy of childhood, presents in many patterns, typically as the easily recognizable signs of leukokoria, glaucoma, strabismus, or vision loss. A small percentage manifest as other more common diagnoses. These more unusual signs can involve any portion of the eye segment, including the orbit and lids, the anterior segment, and the posterior segment, as well as produce systemic illness. This paper deals with the first reported case of retinoblastoma presenting as a spontaneous total hyphema. Accurate diagnosis of similar situations can only be made by means of a high index of suspicion of malignancy and the use of diagnostic tests such as ultrasound and computed axial tomographic scanning.
