Stereotactic brain biopsy using a narrow aperture computed tomography scanner.

A technique for stereotactic brain biopsy with guidance by computed tomography (CT) has been developed and the procedure carried out on a series of 12 patients. A head fixation device, based on the Leksell method, has been designed which allows exact transfer of CT co-ordinates to a Bennett stereotactic frame for the purpose of the biopsy. The development and initial experience of this stereotactic technique in 12 cases is reported and the accuracy of the method confirmed by histological examination and post-operative CT verification of the biopsy site, by means of a small marker inserted at the time of surgery.

Antenatal detection of recurrence of Majewski dwarf (short rib-polydactyly syndrome type II Majewski).

Two cases of Majewski dwarfism are reported. both were the product of the same non-consanguinous marriage and each exhibited the key features of this syndrome: polysyndactyly, short ribs, cleft lip, disproportionately short tibiae and a normal pelvis. The first infant, a baby boy, died shortly after birth, whilst the second was detected prenatally by ultrasound and had female characteristics. Several skeletal dysplasias have been demonstrated in utero by ultrasound, but we believe this to be the first reported case of a Majewski dwarf detected by this method. In view of the difficulty in diagnosis of this syndrome comparison is made with other short rib-polydactyly syndromes.
