retroperitoneales Schwannom

Total

laparoscopic resection by medial-retroperitoneal approach using virtual navigation: two case reports of primary retroperitoneal schwannoma. a CT showed a well-defined round 27 × 24 mm cystic mass (yellow arrowhead). b T2-weighted MRI showed a high-intensity lesion with the main feeder being a branch of the right third lumbar artery (yellow arrow). c PET-CT showed a mass with low FDG uptake. d The locations of the tumor and main feeder were identified before surgery on 3D images

laparoscopic resection by medial-retroperitoneal approach using virtual navigation: two case reports of primary retroperitoneal schwannoma. a CT showed a tumor (white arrowhead) on the dorsal side of the IVC. b T2-weighted MRI showed a high-intensity lesion. c A mass with low FDG uptake was observed on PET-CT. d SYNAPSE VINCENT was used to convert DICOM data of the CT images to 3D images

Laparoscopic

resection of a retroperitoneal schwannoma located in the hepatic hilus. The CT scans of the past 3 years. (A) March, 2011. (B) March, 2012. (C) April, 2013. (D) January, 2014.

Laparoscopic

resection of a retroperitoneal schwannoma located in the hepatic hilus. The results of Abdominal ultrasonography and weighted images of MRI. (A) Abdominal ultrasonography revealed a 2.8 × 2.5 cm solid tumor between hepatic hilus and common hepatic artery. (B) T1-weighted image of MRI showed a heterogenous low-intensity lesion. (C) T2-weighted image of MRI showed a heterogenous high-intensity lesion except for the central area. (D) PET/CT showed a low FDG-uptake mass (max SUV = 3.6).
