Reninoma: A Rare Cause of Endocrine Hypertension.

[Reninoma: A Rare Cause of Endocrine Hypertension]. Acta Med Port. 2019 May 08;: Authors: Marques B, Couto J, Lemos MC, Rodrigues F Abstract Juxtaglomerular tumours are rare causes of secondary hypertension. They typically present with difficult-to-manage hypertension, hypokalemia, hyperreninemia and secondary hyperaldosteronism. The authors describe a clinical case of a 45 years old female patient, with personal history of difficult-to-manage hypertension and hypokalemia since age 35, medicated with four types of anti-hypertensive agents. An analytical study was performed, which revealed secondary hyperaldosteronism [aldosterone 44.3 ng/dL (4 - 28 ng/dL), renin> 1000 mIU/mL (4.4 - 46.2 mIU/mL)]. Abdominal computed tomography scan identified a heterogeneous nodule located in the middle third of the right kidney, with 3.7 cm. Partial nephrectomy was performed and histological analysis confirmed the diagnosis of reninoma. After surgery, the patient had normal levels of aldosterone (9.2 ng/dL) and renin (1.20 mIU/mL), as well as normal blood pressure. The authors want to highlight this potentially curable cause of endocrine hypertension. Surgical resection is the treatment of choice and leads to normalization of blood pressure.

Abstract Kidney cancer is one of the 10 most common cancers in the United States with 90% being attributed to renal cell carcinoma. Men, especially black men, are more likely to be affected than women. Renal masses, either cystic or solid, are best detected with contrast-enhanced, triple-phase computed tomography. Renal tumors are often detected incidentally during a computed tomography scan of the abdomen or chest that was ordered for unrelated symptoms. Hematuria serves as a warning sign that necessitates further evaluation and imaging leading to a diagnosis and treatment plan. Treatment options include active s...

A 37-year-old male, who at the age of 8 years had been treated for right-sided Wilms ’ tumor with nephrectomy, radiotherapy, and chemotherapy, presented with noncirrhotic portal hypertension (NCPH), grade 2 esophageal varices, and ascites. A CT scan demonstrated hypoplasia of liver segments 2 and 3. A liver biopsy showed portal tract fibrosis without cirrhosis, with histological f eatures of NCPH. Liver vein catheterization showed a normal portal pressure gradient of 5 mm Hg while spleen to hepatic vein pressure was 29 mm Hg. NCPH after therapy for Wilms’ tumor is described in children within the first few year...

Conclusions: As a conclusion, laparoscopic radical nephrectomy and IVC thrombectomy is a complex and technically demanding surgery. With advancement of surgical skills as well as technology, more cases of minimally invasive laparoscopic radical nephrectomy and IVC thrombectomy can performed to improve the perioperative outcomes of carefully selected patients in a high volume center.

A 40-year-old male with chronic hypertension since his teens presented to the Emergency Department following a motor vehicle collision. CT scan demonstrated an incidental 1.8 cm renal mass. Partial nephrectomy revealed a vascular tumor with predominantly monomorphic epitheliod cells arranged in sheets and trabeculae with foci of nuclear pleomorphism. Tumor cells were positive for vimentin, CD34, and c-KIT. Juxtaglomerular cell tumor is a rare, benign neoplasm typically found in young adults. Pleomorphism is uncommon and, in combination with older age at diagnosis, can lead to an inaccurate malignant diagnosis.

We describe and analyze the clinical course and imaging findings of a case of a renal inflammatory myofibroblastic tumor (IMT) that is similar to cystic renal cell carcinoma. “Solitary cysts” on the left kidney were found during a health examination of a 60-year-old female. The patient also had hypertension. She had undergone surgeries twice for limb trauma fracture and had no definite record of hepatitis. There was no tenderness with percussion of the kidney area or edema in the lower extremity. The renal function results, including serum creatinine, blood urea nitrogen, and blood urea, were within the normal ...
