Introduction: Ultrasound and computed tomography-guided fine needle aspiration cytology play an important role in the diagnosis of deep-seated lesions such as intra-abdominal and intrathoracic diseases. Objective: To evaluate the efficacy of ultrasound (USG) and computed tomography (CT)-guided FNAC in the diagnosis of abdominal and intrathoracic lesions for one year, from January 2021 to December 2021. Materials And Methods: The study included 58 intraabdominal and 45 intrathoracic lesions. Cytological findings were correlated to clinical and radiographic data to arrive at a definitive diagnosis. Results: Fine needle aspiration cytology was performed at various anatomical sites: liver (24 patients), colon (9 patients), gallbladder (5 patients), ovary (6 cases), spleen (3 cases), mesentery (3 cases), omentum ( 3 cases), cecum (2 cases), pancreas (1 case), subhepatic lesions (1 case), lung (43 cases), mediastinum (2 cases). The most common intra-abdominal disease was metastatic adenocarcinoma of the liver (14 patients), and the most common intrathoracic disease was lung adenocarcinoma (18 patients). Conclusion: Ultrasound and computed tomography-guided fine needle cytology is an excellent method for deep diagnosis in the abdominal and thoracic cavity.

Brain retraction is crucial for adequate exposure during many intracranial procedures. It facilitates the access to the area of interest inside the brain and gives the surgeon the ability to create a corridor to visualize the deeply seated lesions. Retraction-related injury is a well-known complication. A minimally invasive retraction system has been invented and modified to improve the downside of retraction and overcome the complications. The syringe brain port system is a transtubular system composed of simple tools that are available in all medical facilities. It can help the neurosurgeons to achieve brain retraction in a safe, simple, and cost-effective technique. We are presenting a video of how to make this system. Also, we are demonstrating an intraoperative application of this system in a case of a 36-year-old male with deep-seated recurrent right frontal glioblastoma multiforme grade IV.
