“…Ultrasound examination mainly manifested as round lowecho mass with clear boundaries, and some internal echoes were uneven. CDFI showed speckled and striped blood flow signals within the mass (9). Previous study showed that BPGs were solitary, and 40% were located on the dome.…”

“…BPG is a rare tumor derived from the medullary tissue of the bladder wall sympathetic nervous system, which mostly occurs in the submucosa and muscularis mucosa (8). The majority of BPGs are benign, and the only absolute criterion for malignancy is the presence of metastases at sites where chromaffin tissue is not usually found (9). BPGs could be divided into functional and non-functional according to catecholamine content and active degree of release (8).…”

Background: To investigate the imaging findings of bladder paraganglioma (BPG) and improve the imaging recognition and diagnostic accuracy of the disease. Methods:The clinical and imaging data of 10 cases of BPG confirmed by operation and pathology were retrospectively analyzed from the aspects of tumor location, size and morphology, presence or absence of necrosis, cystic change and calcification, and enhancement methods.Results: Of the 10 cases, 7 cases underwent basal and contrast enhanced computed tomography (CT) scan examination, 1 case underwent basal and contrast enhanced MRI scan examination, and 9 cases underwent ultrasonography examination; 5 cases were located in the right wall of bladder, 3 cases were located in the left wall, and 2 cases were located in the bottom wall; 2 cases showed necrosis, 1 case had cystic degeneration, and 2 cases had arcuate and semicircular calcification; both contrast enhanced CT and MRI examinations showed significant post-contrast enhancement; in 9 cases of ultrasonography examination, 5 cases had hypoechoic mass, 3 cases had moderate echoic mass, and 1 case had hyperechoic mass. Conclusions:The imaging findings of BPG have certain characteristics, and combining with clinical history is helpful for accurate preoperative diagnosis.

“…Therefore, these paragangliomas are occasionally diagnosed incorrectly; thus, surgeons are unprepared and the surgery to remove paragangliomas may result in an intraoperative hypertensive crisis and increase the mortality rate (7). Several reviews have been published on paragangliomas of the urinary bladder (8,9); however, non-functioning paragangliomas of the urinary bladder have rarely been reported (10). The present study reports the case of an asymptomatic patient with non-functioning paraganglioma of the bladder, which was detected as a mass on urinary ultrasonography scans.…”

Abstract. Paraganglioma, also termed extra-adrenal pheochromocytoma, may be observed at the base of the skull and neck as well as within the mediastinum and periaortic region. The clinical symptoms of paraganglioma of the urinary bladder include intermittent hypertensive attacks, micturition, headaches and palpitations due to high catecholamine levels; these types of paragangliomas are extremely rare. However, certain bladder paragangliomas do not present with any of these symptoms; thus, surgeons are not pre-warned on how to prepare for their resection. Surgery to remove pheochromocytomas may therefore result in an intraoperative hypertensive crisis and increase the mortality rate. This infrequent type of paraganglioma is only recognized through histo logical examination following surgery. The current study reports the case of a 61-year-old male with urinary bladder paraganglioma. The patient presented with hypertension, which was controlled to within a normal range using diovan and norvasc treatment; in addition, the patient's blood pressure was not altered with urination or postural changes. The patient was not administered an α-blocking agent or a blood volume expander prior to the surgery, and during the partial cystectomy no hypertensive crisis occurred.

“…Paraganglioma may be confused with nested variant urothelial carcinoma because of their nest structures; therefore, zellballen structures in the histopathological examination are very helpful in diagnosis. The majority of tumors have the characteristic zellballen pattern consisting of nest structures separated by thin fibrovascular septa at least focally [4].…”

Paragangliomas of the urinary bladder are rare tumors and can mimic urothelial carcinomas due to some features and can be misdiagnosed. A 71-year-old female was seen for hematuria and there was a solid lesion that measured 3 cm on the urinary bladder at cystoscopy. Treatment approaches for paraganglioma and urothelial carcinoma are very different from each other; therefore differential diagnoses should be made carefully. Although immunohistochemical studies are helpful in differential diagnosis, they may cause misdiagnosis in some cases. In this article, we will discuss the clinical, histomorphological, and immunohistochemical differences between paraganglioma and urothelial carcinomas under their differential diagnosis.
