An unusual presentation of pulmonary echinococcosis.

A case of pulmonary hydatid disease presenting with right supraclavicular cystic swelling is being reported. Radiologically, the cyst had an extension into the chest wall with bony involvement in the form of destruction and thinning of the first and second ribs on the right side. The patient responded to albendazole therapy.

Computed tomographic evaluation of pineal calcification.

A prospective study to ascertain the incidence of normally calcified pineal gland, was carried out in 1000 consecutive patients from different parts of Uttar Pradesh (India), undergoing cranial computed tomography for reasons other than a pineal or parapineal pathology. A total of 167 (16.70%) patients were found to have calcified pineals. Of these 128 were males and 39 females. The incidence rose from 1.16 per cent in the first decade to 31.88 per cent above the age of 50 yr. The percentage incidence of normal pineal calcification was lower than that seen in the Western population. No significant difference was found between men and women in any age group. Although calcification appeared as early as the first decade, this percentage was significantly lower than in the higher age groups. Significantly higher incidence rates were seen in the second decade, third decade and sixth decade onwards.
