We report the case of a large lumbar schwannoma eroding the vertebra and originating from spinal canal with invasion of the retroperitoneal space. We also review all the cases in literature reporting lumbar schwannomas eroding the vertebral bodies and invading the retroperitoneal space focusing on the surgical strategies to manage them. Spinal CT-scan revealed a 44 mm × 55 mm inhomogeneous soft...

Retro peritoneum is the potential space between transversalis fascia of the posterior abdominal wall and posterior parietal peritoneum. It extends from diaphragm to the pelvic brim in its supero-inferior aspect. Retroperitoneal space is sub divided into 3 areas by fascial planes-Anterior renal and posterior renal fascia, which join together lateral to kidneys on either side to form later conal ...

A 66-year-old afebrile man presented with a 10-day history of general fatigue. He had a history of autoimmune pancreatitis and tubulointerstitial nephritis diagnosed from a kidney biopsy of the left kidney. He had been treated with oral glucocorticoids (prednisolone 25 mg/day) for 3 months. He had normal hepatic function, renal insufficiency (creatinine 122 lmol/L) and a leucocyte concentration...

Castleman disease or giant node hyperplasia is a rare disorder of the lymphoid tissue most often involving the mediastinal lymph nodes. We report a case of localized retroperitoneal hyaline-vascular type of Castleman disease. A 35-year old woman presented with mild epigastric pain with radiation to the back. Amild anemia was the only abnormal associated finding. Abdominal ultrasound and CTscan ...

BACKGROUND Abdominal and retroperitoneal Castleman's disease could present either as a localized disease or as a systemic disease. Castleman's disease is a lymphoid hyperplasia related to human Herpes virus type 8, which could have an aggressive behavior, similar to that of malignant lymphoid neoplasm mainly with the systemic type, or a benign one in its localized form. METHODS The authors re...

Retroperitoneal liposarcoma is a rare tumor. The dimension and weight of liposarcoma are variable; those over 20 kg are called 'giant liposarcoma'. Herein, we report giant retroperitoneal liposarcoma measuring 45 cm in diameter and 25 kg in weight encasing the entire left kidney and adherent to adjacent structures. A 71-year-old woman presented for a regular checkup. Image study revealed a huge...

BACKGROUND Although is complex to identify the factors responsible for the important growth in obesity all over the world, the main causes are increased consumption of energy, highly saturated fats and sugars, and reduced physical activity. AIM To compare rats with normal and supplemented diet with sucrose in relationship to body mass, weight of gonadal and retroperitoneal fat and Lee index. ...

BACKGROUND To determine whether MRI feature analysis can differentiate benign retroperitoneal extra-adrenal paragangliomas and schwannomas. METHODS The MRI features of 50 patients with confirmed benign retroperitoneal extra-adrenal paragangliomas and schwannomas were retrospectively reviewed by two radiologists blinded to the histopathologic diagnosis. These features were compared between two...
