✓ A case of tuberculous brain abscess in a 52-year-old woman is presented. The computerized tomographic (CT) scan demonstrated a multilocular space-occupying lesion in the right parietal area, surrounded by a thick hyperdense enhancing rim. It is suggested that a relatively long clinical history together with the appearance of a thick-walled abscess-like lesion on the CT scan may indicate the diagnosis of a tuberculous brain abscess.

✓ A case of primary osteogenic sarcoma of the sellar and parasellar region is described. A biopsy performed through the transnasal transsphenoidal approach appears to be the best method of establishing the diagnosis in lesions in this location. A previous case, documented in the German literature, is discussed together with the case presented here.
