Astrocytomas are tumors that arise from astrocytes-star-shaped cells that make up the "glue-like" or supportive tissue of the brain. Astrocytomas can appear in various parts of the brain and nervous system, including the cerebellum, the cerebrum, the central areas of the brain, the brainstem and the spinal cord. The main objective of this study was to detect the sensitivity of the CT scan in diagnosis of the brain astrocytoma, in patients who were confirmed as brain gliomas using computerized tomography of the brain versus brain tissue biopsy after surgery. One hundred and one patients were included in this study. Bio-data collected for these patients (age, gender), radiographic appearance, contrast enhancement and the site of the tumor, were statistically analyzed. Out of the 101 patients with brain gliomas, 52 (51.5%) were male whose ages ranged between 1 and 80 years, and 64 (63.4%) cases were diagnosed as astrocytoma by CT. This study concluded that the CT brain was sensitive in the diagnosis of brain astrocytomas.

segment compatible with probable hepatocellular carcinoma in a non-cirrhotic liver. Hepatic volumetry and previous preanesthetic assessment were performed with liver, cardiac and pulmonary function tests. Given the insufficient hepatic remnant, and the large tumor burden that it represented, it was decided to perform an ALPPS in order to obtain a more rapid liver hypertrophy. Results: The first stage was performed by laparoscopic technique, achieving right portal ligation (the anterior and posterior branches separately) and the hepatic transection without the need for Pringle's maneuver. The postoperative evolution was without complications. After 10 days, a new abdominal tomography was performed to assess the hypertrophy. A hepatic remnant of almost 40% is achieved. We proceed then to the second stage of the ALPPS, this time with an open approach. The hepatic transection is completed with ligature of the right hepatic artery, control of the right bile duct and section of the hepatic veinhe procedure was without complications, did not require blood transfusion or vasopressor support, extubation was achieved and transfer to ICU for surveillance where it was 2 days. He had no signs of liver failure, and was discharged at 8 days. The pathology reveals hepatocelluar carcinoma on a non-cirrhotic liver. Conclusion: ALPPS is an alternative in the treatment of liver tumors where the liver remnant is insufficient, and because of its tumor biology a hypertrophy is required in less time or when the other forms of hypertrophy have failed. However, it is a procedure that can have high morbidty and mortality, which is why it is important to select patients in a multidisciplinary team.
