Introduction:The computed tomography (CT) guided stereotactic biopsy (STB) is considered as method of choice for biopsy of intracranial mass lesions. However, it's disadvantages are frame fixation, time requirement for transportation between CT scan suit to the operation theater with added much higher equipment cost in the relatively resource scarred developing country. Ultrasound-guided biopsy (USGB) is relatively simpler, economical, less time consuming, and real-time procedure.Clinical Materials and Methods:Thirty-seven consecutively admitted patients with supratentorial brain tumors, who underwent biopsy of the lesion using CT compatible stereotactic and ultrasound-guided (USGB) procedure formed cohort of the study. Based on location and size of the lesions, the cases were divided into two groups, superficial and deep. Twenty-two patients underwent ultrasound-guided biopsy and 15 with STB.Results:The diagnostic yield of STB was 93% and 91% for ultrasound-guided biopsy. The mean operation time of STB group was 149.00 min and 94 min for USGB, which was statistically significant. Two cases in each group developed hematoma; however, one case in USGB group needed surgical evacuation. The real-time monitoring detected two hematoma intraoperatively, which were further also confirmed on postoperative CT scan head.Conclusions:The ultrasound-guided biopsy procedure (USGB) was simple, relatively shorter time-consuming procedure and equally efficacious and utilizing economical equipment and can act as a safer alternative to CT STB process for biopsy of the intracranial mass lesion. Furthermore, USGB also provided intra-operative real-time monitoring, which provided clue for close monitoring in the postoperative period after completion of biopsy to look for development of fresh hematoma development not only at the biopsy site but also along the biopsy track and adjoining area. Perhaps, a longer period of ultrasonic monitoring following the procedure would be of greater help to detect hematoma formation, which is one of the most common complications of the biopsy procedure.

“…The relationship with functional areas on the lower faces of temporal, frontal and occipital lobes may be accurately detected with this technique by adding fMRI images to conventional ones. Further advantages of Neuronavigation are in establishing tumour boundaries, helping to avoid eloquent areas when treating small deep-seated lesions, assisting in endoscopic procedures and frameless biopsies [15][16][17][18][19][20] . Compared with conventional non-assisted neurosurgery, the Neuronavigation system reduced the invasiveness of procedures [21][22] .…”

We propose critical considerations on the usefulness of CT, MRI, and fMRI imaging fusion for the treatment of skull base lesions evaluating 41 cases (24 meningiomas: six petroclival, seven clinoidal, four olfactory, two in the foramen magnum, two spheno-petro-clival, one in the planum sphenoidale, one in the posterior pyramid and one in the PCA; five acoustic schwannomas, three epidermoids, two pituitary adenomas, two craniopharingiomas, two posterior fossa aneurysms, one trigeminal schwannoma, one dermoid and one juvenile angiofibroma).Data were collected, fused, integrated and reconstructed by a dedicated Stealth-Station system for Neuronavigation. CT images were acquired on axial non-overlapping slices, 1-3 mm thick; MRI images were obtained with a 1.5 T system, same FOv and thickness.During surgery the Mean Fiducially Error measured at 6 cm depth and anatomical distortion due to CSF loss was evaluated.Neuronavigation was possible in all cases and successfully applied in preoperative planning and during surgical procedures.The Mean Fiducially Error at 6 cm was 1.7 mm. CSF loss during surgery produced modifications on planned anatomy in a mean value of 0.6 mm.In all cases, imaging fusion for pre and intra-operative neuronavigation provided great advantages in the choice of the best approach, placing of bone flap, correct definition of tumour boundaries and meningeal implant, relationship with functional areas, early identification and real-time correction of the surgical route with respect of deep normal or distorted anatomic or pathologic structures and their eventual encasement or involvement by the pathologic primary process.Neuronavigation appeared ideal for skull base meningiomas making surgical manoeuvres safer, more effective and less invasive. In skull base lesions, CSF loss appeared not significant due to the fact that posterior fossa structures are strictly connected to each other and to the bone, thus are poorly affected by surgical deliquoration. We propose the possible extension of imaging fusion technique with the aim of optimizing the target in radiotherapy for intracranial tumours.Utilità della tecnica di fusione dell'immagini nel trattamento delle lesioni del basicranio RIASSUNTO -Vengono proposte delle considerazioni critiche sull'utilità della fusione di immagini TC, RM, fRM nel trattamento delle lesioni del basicranio.Sono stati valutati 41 casi di lesioni del basicranio (24 meningiomi: 6 petroclivali, 7 clinoidali, 4 olfattori, 2 del forame 300 è stato utilizzato un sistema dedicato StealthStation da Neuronavigazione per la raccolta, fusione e ricostruzione dati. Le immagini TC sono state acquisite su piani assiali non sovrapposti da 1-3 mm di spessore a Fov 24; le immagini RM sono state ottenute con un apparecchio da 1.5 Tesla con lo stesso spessore e campo di vista. In corso di intervento neurochirurgico sono stati valutati l'Errore Fiduciario Medio misurato a 6 cm di profondità e la distorsione anatomica dovuta alla perdita di CSF.La neuronavigazione è stata possibile in tutti i casi ed ...
