[Repeated operations for recurrent lumbar disc herniations]. / Wielokrotne operacje przepuklin jadra miazdzystego w odcinku ledzwiowym.

A study of 73 patients who underwent reoperation for persistent or new complaints following initial lumbar discectomy is presented. 32 patients showed true recurrence of disc herniation (6 on the contralateral side) and 41 at a different level. 14 patients needed 3rd operation. Final results were evaluated using the Functional Economic Rating Scale elaborated by Prolo. Mean score for group operated on twice was 8.1 according to Prolo and 7.1 for group operated on 3 times.

Meningiomas of the lateral ventricles of the brain in children.

Meningiomas of the lateral ventricles of the brain are rare tumours, accounting for approximately 0.5-5% of all intracranial meningiomas. Their natural history and symptomatology and the possibilities of early diagnosis are presented. The intraventricular location of the slow-growing benign mass provides a compensatory mechanism in the form of reserve space, which contributes to the delay in clinical demonstration of symptoms and signs. This makes the choice of diagnostic procedure an essential problem. CT and MRI are useful in detecting these masses, and magnetic resonance angiography (MRA) has also proved to be of great value in demonstrating the vascular supply of the tumour. This paper deals with two cases. In case 1 CT, MRI and MRA and in case 2 CT examination proved to be very useful. The tumours were removed by a transcortical approach in the posterior area.

Metastatic carcinoid tumor in the brain.

The case presented describes a metastatic carcinoid in the cerebral hemisphere of a 52-year-old woman. The onset of the disease was in the form of stroke, CT-examination showed hemorrhagic focus and edema. A craniotomy was carried out and the lesion was removed. Histological diagnosis stated that the tumor was a carcinoid accompanied by a massive hemorrhage. Two and a half months later, another CT-examination revealed a second tumor in proximity to the site of operation, which was then treated palliatively by means of Co 60 radiation. The patient died 1.5 months later. General autopsy showed two other neoplastic tumors: a smaller one in the left lung and a bigger one (possible primary) in the stomach. In the report special attention was paid to an unusual cellular polymorphism especially prominent in the tumor formerly irradiated.
