CT-guided excision of osteoid osteoma is a new surgical technique that enables accurate resection of the nidus during 1-day hospitalization. We present 5-year results in 42 patients (26 males and 16 females, mean age 18 years, range 3-46). In 40 out of 42, complaints disappeared immediately after the procedure. The recovery period was short and the return to normal activity was faster than in the open surgical approach. Complications were minimal and transient.

Progress in diagnostic radiology and pathology during the past decade has changed the approach to diagnosis of mediastinal masses. Diagnosis by CT-guided needle biopsy (CTNB) has replaced open biopsy and mediastinoscopy. CTNB of mediastinal masses is accurate, reliable and safe. It is done under local anesthesia, in ambulatory patients and is tolerated well. Between July 1987 and April 1997 we performed 67 biopsies in 63 patients aged 6-86 years; 33 were women (average age 40.8 years) and 30 men (average age 38.3 years). 57 of 67 biopsies were core biopsies for histologic examination and 10 were cytologic biopsies. In this report we concentrate on the 57 core biopsies. 41 of the biopsies were diagnostic; in 3 of them no evidence of malignancy was found. In 38 of the biopsies a tumor, malignant or benign, or an inflammatory process was diagnosed. In 24 of the biopsies the diagnosis was lymphoma. In 16 there was not enough material for diagnosis. We repeated the biopsy in 4 of the latter due to high suspicion of malignancy and reached a diagnosis in all 4 of them. In 6 the diagnosis was reached only by operation. The biopsies were from all compartments of the mediastinum. There were no complications such as pneumothorax or bleeding, except for 1 case of mild hemoptysis. In conclusion, CTNB of mediastinal lesions is accurate, safe and relatively cheap. In 72% a diagnosis was reached in the first attempt and a second attempt raised the diagnostic rate to 79%. We believe that CTNB should be the first step in tissue diagnosis of mediastinal masses, including those with a high suspicion of lymphoma.

Ct-Guided Core Needle Biopsy Of Abdominal, Pelvic And Retroperitoneal Masses

CT-guided core needle biopsy of abdominal, pelvic and retroperitoneal masses is accurate and safe and can be performed on an outpatient basis. Between 1987 and 1995, 809 patients (age range 1-87 years) underwent 851 biopsies (minimal lesion diameter 1 cm). Cutting needles were always used, facilitating both cytological and histological diagnosis while minimizing risk of complications. A positive result (malignant, inflammatory or infectious) was obtained in 69% of the 809 and a negative result (normal tissue) in 17.4%, while in 13.6%, material for diagnosis was insufficient. Biopsy was repeated in 42 of them in whom radiological or clinical suspicion of malignancy was high. In 24 (60%) a positive result was obtained after the second biopsy.

Significant complications occurred in 7 (0.8%). 1 hemo-rrhaged following liver biopsy and required blood transfusion. Pancreatitis occurred in 6 (2.6%) following pancreatic biopsy. An intra-abdominal fluid collection in 1 necessitated percutaneous drainage. There was no mortality following the procedure and no documented case of needle-tract seeding of tumor. All outpatients were discharged within 3 hours of completion of the biopsy, without ill effects.
