Bilateral Renal Lymphangiectasia

Bilateral Renal Lymphangiomatosis: A Case Report and Literature Review

Renal lymphangiomatosis is a rare congenital condition characterized by the abnormal development of lymphatic channels in the kidney, resulting in cystic dilatations. While more commonly observed in children, it can occur in adults but is extremely rare. Clinical manifestations range from asymptomatic cases to symptoms such as abdominal pain, hypertension, and renal dysfunction. In this case report, we present a rare case of bilateral renal lymphangiomatosis in an eight-year-old male with high blood pressure. Renal ultrasound revealed bilateral kidney enlargement and perinephric hypoechoic collections with septations consistent with lymphangiomatosis. The diagnosis was confirmed through CT imaging which shows bilateral non-enhancing perinephric collections. As a part of the patient's management plan, bilateral perinephric cystic lesions were successfully aspirated without complications. In conclusion, accurate diagnosis is crucial for appropriate management decisions, and treatment primarily focuses on conservative measures to manage associated hypertension, reduce lymphatic fluid accumulation, and alleviate pain, reserving invasive interventions for severe cases or complications.

Renal lymphangiectasia in pediatric population: case series and review of literature

Renal lymphangiectasia is a rare disorder where perirenal, parapelvic, and/or intra-renal lymphatics are dilated. The clinical presentation of renal lymphangiectasia can range from asymptomatic to renal failure. Ultrasound, computed tomography and magnetic resonance imaging have been used for the diagnosis. Management of such cases varies from conservative to nephrectomy. We report three cases of pediatric renal lymphangiectasia that were managed by recurrent sclerothera-pies and medical supportive treatment at our institution. A literature review is also presented. To the best of our knowledge, there are 83 reported cases in the literature, 60 adults and 23 pediatrics.

Renal Lymphangiectasia: An Unusual Mimicker of Cystic Renal Disease - A Case Series and Literature Review

Cystic renal lesions are commonly seen on a daily basis in abdominal imaging. Even though most cystic renal lesions are benign simple cysts, complex and multifocal cystic renal diseases are also common with a vast number of differentials. One of the rare mimickers of this condition is renal lymphangiectasia, and the disease can be diagnosed if radiologists are aware of the imaging findings, and this can help the physician to offer the appropriate treatment. We report a case series of five cases in our hospital and also review the literature on renal lymphangiectasia, including its pathophysiology, clinical presentation, imaging appearances, complications, treatment, and differentials.

Posttransplant Intrarenal Lymphangiectasia

Renal lymphangiectasia is an extremely rare benign condition in the setting of transplanted kidneys. We describe a 50-year-old female with a past medical history of lupus nephritis and renal transplants who presented with right lower quadrant pain and was found to have intrarenal lymphangiectasia on imaging and laboratory tests. The patient was treated with percutaneous drainage initially and then wide peritoneal fenestration and omentoplasty. An extremely rare adult case with intrarenal lymphangiectasia thirteen months after kidney transplant was described in this study. Imaging, particularly computed tomography (CT) and magnetic resonance imaging (MRI), plays a key role in the diagnosis of renal lymphangiectasia.

Refractory hypertension due to unilateral renal lymphangiectasia: An uncommon case with a surgical solution

We describe a case of unilateral renal lymphangiectasia (RLM) in a 30-year-old male with severe, refractory hypertension (HTN) and end-organ effects despite five anti-hypertensives. After diagnostic testing, the patient ultimately underwent a successful right laparoscopic nephrectomy with significant improvement of HTN. We review the literature regarding the pathophysiology and management strategies of HTN in patients with renal lymphangiectasia.

•

Renal lymphangiectasia (RLM) is an uncommon cause of secondary hypertension.

•

RLM is diagnosed using conventional imaging which notes dilated perinephric and/or peri-pelvic lymphatic channels.

•

RLM is believed to be an uncommon benign and congenital developmental malformation of the renal sinus lymphatics.

•

Clinically the condition is most often asymptomatic, but symptoms may include flank pain, hematuria, ascites, weight loss, HTN, or other vague constitutional symptoms.

•

Antihypertensive therapy is the mainstay of treatment, but refractory drainage and/or nephrectomy may improve BP control.
