Using computed tomographic scanners, stereotactic guided brain usually permits safe
and accurate pathologic dianosis.
In our department of between 1991 and 1995, 35 patients underwent CT guided
stereotactic biopsy and/or craintomy with CRW stereotactic frame, and following results
were obtained.
1) All lesions were supratentorial. As surgical intervention for the diagnosis, biopsy
was carried out in 25(71.4%), aspiration of cystic content was in 2(6%), and
stereotactic guided craniotomy was in 8 cases(23%) respectively.
2) A positive diagnosis could be obtained in 34 cases(97.1%), and inconclusive
diagnosis disclosed in only one case(2.9%). Positive diagnoses included : 10 cases of
astrocytoma(28.6%), 4 cases of glioblastoma(11.4%), metastasis, germinoma, and
meningioma in that order.
3) It seemed to be difficult to ascertain a grade and to search for any presence of
mixed area in glioma cases, because open craniotomy was not carried out in all cases.
4) The biopsy specimens were generally obtained with cup forceps, however a spiral
needle core device with outer probe was very useful for obtaining tissue of tumor for
an unavailable case with cup forceps.
5) The immediate post-operative CT scan after 3-4 hours of proce¿©re gave
information for accurate site of target under location of air bubble, and any evidence of
complication such as hemorrhage.
This study provides evidence that CT-guided stereotactic biopsy is a reliable, simple,
and safe method for obtaining histological dianosis of intracranial mass lesions.
