Aneurysmal bone cyst in temporal region is rare. It is a benign condition and may extend intracranially. Total surgical removal is recommended, whenever possible in one stage or in multiple stages. Prognosis is excellent and total removal will effect a cure. An unusual case of aneurysmal bone cyst of temporal region is reported.
A case of dermatofibrosarcoma protuberans of scalp involving the underlying bone, operated after recurrence by taking safety margin of 3 cm and skin deficit covered by transposition flap, is being reported. Modality of treatment has been discussed.
A case of lateral ventricular teratoma in neonate, where near total excision of tumour was done, is being reported with the review of literature.

Twenty-three children under the age of 6 1/2 years developed immediate unilateral weakness after an apparently minor head injury. Computed tomography disclosed a hypodense lesion in the basal ganglia. The lesion appeared to be caused by an infarct in the basal ganglia. All but one of the children recovered completely within 4 months.
Bilateral acute epidural haematoma are found in 2-10% cases. They are associated with high mortality. We have analysed twenty cases of bilateral epidural haematoma found over a period of eleven years. In 60% cases haematoma was across the midline and in 40% cases haematoma was found at different locations on either side. Skull fracture was present in 95% cases. Mortality in our series was 20%.
