Severe emphysema treated with endobronchial valves
A 53-year-old male patient, suffering from severe emphysema and hyperinflation, was treated with endobronchial valve deposition 鈥 an interventional procedure aiming to reduce the lung volume in order to improve ipsilateral diaphragmatic motion and subsequently, the patient鈥檚 respiratory condition. An UHR chest CT was indicated for post-procedural evaluation.
A massive paraspinal dermal hemangiosarcoma 鈥 palliative or surgical therapy?
A 16-year-old female dog, suffering from a massive paraspinal mass on her left lower back for the past 6 months, was referred for palliative treatment as the mass was considered nonresectable due to its size and location.
