[Percutaneous radiofrequency ablation of osteoid osteoma: results from 9 years of experience in a third-level center.].

Introduction: Osteoid osteoma is a benign bone tumor that accounts for roughly 2-3% of primary bone tumors and up to 10-12% of benigns bone neoplasms. It is most commonly seen in young adults, and shows male predominance. Over the last years, minimally invasive thermal ablation techniques such as radiofrequency ablation have gained popularity over classical surgery.

CT-Guided Trans-osseous Biopsy: Experience in 24 Patients.

Purpose: The objective of this study is to assess the effectiveness of computed tomography-guided trans-osseous biopsies in deep-seated lesions and report encountered complications.

Materials And Methods: A retrospective cohort study was performed which included twenty-four patients with pathologic medical history and lesions non-accessible by common approaches. Exclusion criteria include patients who could be biopsied without trans-osseous access, as for example procedures aided with hydro- or pneumo-dissection.

[Presurgical hypogastric lymph node marking under CT guidance, aided by hidrodissection].

Introduction: Pre-surgical lymph node marking is an established medical procedure of vital importance in the treatment of cancer patients.

Materials: A 60-year-old man with a history of prostatic adenocarcinoma in a plan for resection of hypogastric adenopathy. Image guided pre-surgical marking was indicated.

[Hypoxemia, pleural and pericardial effusion after splanchnic neurolysis. A case report.].

Introduction: Alcohol neurolysis of splanchnic nerves is a valuable tool for treating visceral intractable pain from the upper abdomen in cancer patients. It is a safe and effective procedure, yet not risk free. It’s most common adverse effects are mild and self-limited.

[Retroperitoneal lymphadenopathy trans-vertebral image-guided biopsy: a case report].

Introduction: Transosseous biopsy allows sampling of lesions that are difficult to access with conventional techniques. Its use avoids surgeries.

Objective: To present a clinical case in which retroperitoneal percutaneous biopsy with trans vertebral approach was used.
