Cystoscopy, Right Ureteroscopy, and Ureteral Stent Insertion with Aborted Biopsy and Potential Laser Ablation of a Right Renal Mass
Ryan A. Hankins, MD
MedStar Georgetown University Hospital
This article describes a case of a 58-year-old male patient with a renal mass, which was incidentally discovered on an imaging of chest CT scan, without any signs and symptoms indicative for renal masses. The patient has no history of ureteroscopy before, and no prior history of urolithiasis. The multiphasic, contrast-enhanced abdominal CT scan shows 2.5-cm hyperattenuating enhancing mass in the upper pole of the right kidney. Transverse unenhanced CT image shows hyperattenuating mass with no evidence of fat. Transverse CT image shows enhancement of the mass from 60 HU to 116 HU. The chest CT scan showed no abnormalities. This video describes a complex urological procedure that initially aimed to perform diagnostic and potentially therapeutic intervention but was modified due to anatomical constraints. The procedure demonstrates the importance of surgical adaptability and the role of staged approaches in urological surgery.
Thyroid Biopsy: Fine-Needle Aspiration for Multinodular Goiter

Thyroid nodules are common with a higher prevalence in women and the older population. They can be found in more than 50% of the older population. Malignancy risk is reported to be 7–15% depending on age, sex, radiation exposure history, and family history. Thyroid nodules can be detected either by palpation or incidentally by imaging done for irrelevant purposes. About 16% of chest CT scans show an incidental thyroid nodule. Subsequent ultrasound scans would evaluate the nodule size and characteristics. If the nodules meet the biopsy criteria based on TIRADS (Thyroid Imaging Reporting and Data Systems) criteria, referral for fine-needle aspiration biopsy (FNA) is necessary. This video delivers a thorough demonstration of the correct technique for ultrasound-guided thyroid FNA with rapid on-site cytology evaluation (ROSE).
Brain Biopsy of a Suspected Cerebellar Lymphoma

In neurosurgery, brain biopsy is an essential tool for providing adequate histological sampling in neoplastic and non-tumorous lesions. There are two main techniques in obtaining tissue samples: open biopsy requiring craniotomy or needle biopsy. Needle biopsies allow for minimally-invasive tissue diagnosis with less risk of operative morbidity for the patient. This video article show a frameless needle biopsy of a cerebellar lesion using the Brainlab varioguide system.
