Ectopic immature renal tissue over the dorsum of lumbar and sacral area in two infants.

During reparative surgery for meningomyelocele of the lumbar area, a 7-week-old female infant was found to have a small, well-delineated, subcutaneous, renal blastema. A 3-month-old female infant was found to have immature renal tissue, consisting of glomeruli and tubules, in a soft tissue swelling dorsal to the sacrum. Neither of these patients showed neurologic or renal abnormalities. The second patient has had a disease-free follow-up period of six years. The possible etiology and significance of these benign findings and their relation to the origin of Wilms tumors are discussed.

Vasospasm following transcranial removal of large pituitary adenomas. Report of three cases.

The authors report three cases of cerebral vascular spasm following transfrontal removal of large pituitary neoplasms. One patient awakened from surgery hemiparetic, but has since recovered. A second patient developed hemiparesis with confusion on the fifth postoperative day and eventually died. The third patient developed hemiplegia on the tenth postoperative day, but recovered completely. Vascular spasm was documented angiographically in all three cases. Possible mechanisms underlying this unusual complication are discussed.

Successful conservative management of Gorham disease of the skull base and cervical spine.

Gorham's disease, also called massive osteolysis or vanishing bone disease, is an enigmatic condition caused by endothelial proliferation occurring in bone and soft tissue. Death is frequent when there is spinal or visceral involvement. We present a case of spinal and skull base Gorham's disease that was reversed by radiation therapy administered while the spine was supported by a halo vest. The literature is reviewed.
