RETROPERITONEAL TUMORS SIMULATING GENITAL TRACT NEOPLASMS

Obstetrical & Gynecological Survey, 1946
Summary The subject of retroperitoneal and mesenteric tumors has been discussed. Both have common derivation in the extracoelomic mesenchyme. Lacking a satisfactory grouping encompassing all these tumors, a suggested classification is proposed. Tivelve cases front our records (an incidence of 1:1,093) are tabulated.

Castleman disease mimicking an aggressive retroperitoneal neoplasm

Abdominal Radiology, 1994
A case of Castleman disease of the retroperitoneum in a 26-year-old woman is presented. Sonography, computed tomography, and magnetic resonance imaging demonstrated a large retroperitoneal mass with somewhat heterogeneous imaging characteristics. Although a definitive preoperative diagnosis was not possible, magnetic resonance imaging was useful in ...

Retroperitoneal germ cell neoplasm: MR and CT

Magnetic Resonance Imaging, 1992
A case of germ cell neoplasm in an undescended retroperitoneal testicle is reported. CT revealed a large mass most consistent with a chronic hematoma. MRI demonstrated findings typical for neoplasm, and this was confirmed on biopsy.

Adrenal Myelolipoma Simulating a Retroperitoneal Malignant Neoplasm

Journal of Urology, 1981
We describe a case of a large myelolipoma (15 by 12 cm. maximum diameter) that was removed surgically and resembled clinically and semeiologically a malignant retroperitoneal tumor. The patient also had chronic pancreatitis and cholelithiasis. Experimental findings, as well as the frequent association of myelolipomas (usually small) with several ...

Rare Primary Retroperitoneal Neoplasms.

The Israel Medical Association journal : IMAJ, 2020
Primary retroperitoneal neoplasms (PRN) arise from diverse retroperitoneal tissues. Soft tissue sarcomas (STS) comprise the majority and are well studied. Other non-sarcomatous PRN are very rare and less familiar.To evaluate the clinicopathologic and radiologic features of non-sarcomatous PRN, as well as the outcome of complete tumor resection (TR ...

[Nonorganic retroperitoneal neoplasms of the pelvis].

Khirurgiia, 1989
The results of observations over 116 patients with nonorganic retroperitoneal tumors of the pelvis in the diagnosis of which computerized and ultrasonic tomography were used among other methods showed these methods to expand the possibilities of early diagnosis significantly. Analysis of 83 operations conducted on patients with nonorganic tumors of the

[Computed tomography of retroperitoneal neoplasms].

Zhonghua zhong liu za zhi [Chinese journal of oncology], 1993
CT findings of retroperitoneal neoplasma in 50 cases (51 tumors) were reviewed. There were 28 (55%) malignant tumors and 23 (45%) benign ones. MFH and liposarcoma were the most common malignant tumors and neural origin tumors were the most common benign ones. Differentiation is difficult on the basis of CT features alone.
