“…Abdominal PGLs are mostly a single irregular mass in the organ of Zuckerkandl or bladder base [ 16 – 18 ]. These current results show the 51 cases were all solitary, and most of them were located around the retroperitoneal abdominal aorta, which was consistent with previous reports [ 19 ]. Previous literature [ 20 , 21 ] reported an average age of 49.8 (16–76) years and with an equal incidence in male and female.…”

Background and Objectives. Recurrence and metastasis are the most important factors influencing the survival rate of patients with paragangliomas (PGLs). Accurate preoperative prediction of the risk factors and developing a reasonable therapy strategy can reduce the recurrence rate. Computed tomography (CT) is regarded as the preferred imaging modality for the initial evaluation of PGLs. However, only a few studies have investigated the relationship between CT features and the invasiveness of PGLs. Therefore, we investigated the prognostic importance of CT features for PGLs. Methods. We studied 51 abdominal PGL patients at the First Affiliated Hospital of Bengbu Medical College, Tongde Hospital, and Sir Run Shaw Hospital, Hangzhou, Zhejiang Province, China, from June 2009 to May 2019. Thereafter, the clinical research data, tumor biomarkers, and CT features were compared between the aggressive PGLs and the nonaggressive PGLs using independent-samples t-tests and chi-square tests. Results. Of the 51 cases, 43 were benign and 8 had malignant tendencies. Postoperative recurrence and metastasis were more likely to occur when the tumor diameter was >8 cm or/and the enhancement degree was not obvious. Clinical symptoms, tumor markers, sex, age, and CT image characteristics including morphology, presence of cystic degeneration, “pointed peach” sign, calcification, hemorrhage, enlarged lymph nodes, and peritumor and intratumor blood vessels were not significantly different between the two groups p > 0.05 . Conclusion. Our findings suggest that CT features, including size >8 cm and enhancement degree, could provide important evidence to assess risk factors for aggressive PGLs.

“…After adapted imaging including an assessment of extension, the standard of care is to perform a pre-operative CNB to adapt the medical and surgical strategy in the MTB [ 3 , 4 ]. In our case, MDM2 amplification by FISH was useful to differentiate WD LPS vs. other benign lipomatous tumors that can grow in the retroperitoneum [ 7 ]. The fact that influenced the therapeutic strategy was that the thigh sarcoma was MDM2 negative on immune histochemistry (IHC) and molecular biology proved that the two sarcomas (the thigh sarcoma and the retroperitoneal sarcoma) were two different types of sarcomas and that one was not the metastasis of the other one, which could have led to a non-surgical treatment [ 3 ].…”

Sarcoma is a rare type of tumor that can arise in the different types of connective tissues. Symptoms vary depending on the size, type, and location of the tumor. Management and surgery should be performed in a referral sarcoma center with a molecular biology platform and a dedicated medical staff. A preoperative percutaneous core needle biopsy (CNB) is required to tailor the medical and surgical strategies. In this report, we describe the case of a well-differentiated retroperitoneal liposarcoma (WD LPS) discovered in the context of recurrent cystitis on an abdominal CT scan, synchronously occurring, with another different type of sarcoma, undifferentiated pleomorphic sarcoma (UPS) developing in the thigh, discovered because of sciatic pain. This extremely rare condition was confirmed by the molecular analysis and justifies a specific strategy taking account of the differential risk. This event should also encourage genetic counseling.

“…In our case, the images were interpreted as a retroperitoneal tumour intimately related with the diaphragm and the left adrenal gland was normal. During the diagnostic work-up of a retroperitoneal mass, a percutaneous biopsy is of utmost importance to help guide the therapeutic strategy 12. Having discarded the possibility of a functional tumour, we effectively did a percutaneous biopsy using a posterior approach.…”

Intradiaphragmatic bronchogenic cyst: report of a rare new case

et al. 2022

View full text Add to dashboard Cite

Bronchogenic cysts (BCs) are congenital abnormalities commonly found within the mediastinum. Diaphragmatic location is extremely rare. We present a woman in her 60s with an asymptomatic intradiaphragmatic BC. The patient underwent complete surgical resection with primary closure of the left hemidiaphragm. BCs should remain a differential diagnosis of any soft-tissue mass in the region of the diaphragm. Complete surgical resection is recommended even in asymptomatic patients to avoid complications such as infection, rupture, bleeding or malignant transformation.
