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.

[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.

Frozen abdomen complicated with midline heterotopic peritoneal ossification: case report.

Background: Heterotopic ossification consists in abnormal differentiation of mesenchymal cells into osteoblastic cells, which may occur in the abdominal cavity.

Case Report: A 54-year-old male who presents with small bowel obstruction, performing a laparotomy, adhesiolysis, and managed with an open abdomen with Bogota bag; the abdominal wall was closed on the 5 post-operative day. Due to recurrent symptoms of intestinal obstruction, he required a re-laparotomy after 14 days, finding a frozen abdomen with midline calcified peritoneum.
