RESUMO
Cherubism is a disease that usually affects the jaws in the paediatric population, mostly below five years of age. Radiologically, it closely resembles fibrous dysplasia and other giant cell lesions of the mandible. Computed tomography (CT) is helpful in defining the true extent of cherubic lesions, which is often not possible on radiographs due to the overlapping facial bones. We describe the radiographical and CT features of cherubism in a 12-year-old boy and highlight the ability of multidetector CT and various post-processing techniques to accurately depict the anatomical extent of the cherubic lesions.

A homocystinuric child presented with a secondary pupillary block glaucoma due to anteriorly subluxated lens. After removal of the subluxated lens, a suture supported posterior chamber IOL was implanted. Postoperative complication of cerebral venous thrombosis following general anaesthesia was managed with high doses of pyridoxine special diet and drugs.

We report our experience with colour Doppler sonography (CDS) in 20 normal subjects and 25 patients with intraocular space-occupying lesions. The technique provided an in vivo cross-section of the vascular topography of space-occupying lesions in real time. Colour coding and spectral analysis helped to determine the direction and pattern of blood flow. CDS was found to be a useful diagnostic adjuvant, a guide to the treatment protocol, and helped in monitoring the progress of the disease. In conditions of the eye where unclear media hindered a clinical evaluation, CDS sonography was a safe, easily reproducible and non-invasive investigative tool. With further technical advances in waveform analysis and quantitative assessment, CDS holds promise as an investigative modality of choice in the future.

A full term female baby at birth showed the features of Fraser's syndrome viz. upper lid coloboma, cryptophthalmos, abnormal groove over temporal region, dysmorphic facies, hypospadias and bilateral syndactyly. On ultrasound examination of the abdomen and left orbit, maldeveloped kidney and eyeball were found. Other siblings were not affected. The child died at the age of 3 months.

Melanocytoma of the optic disc is a benign lesion. We report here a patient with melanocytoma who presented with gradual diminution of vision. On examination the left eye fundus showed a mass uniformly dark black in colour, on the optic disc occupying the superotemporal quadrant. The mass completely obscured the fluorescence on fluorescein angiography and was thus differentiated from malignant melanoma.
