Bilateral renal angiomyolipoma with venous invasion: A case report.

Renal angiomyolipoma (AML) is a rare benign tumor of the kidney, often detected incidentally on radiological images as the presence of macroscopic fat characterizes them. In the majority of the cases, they are usually sporadic. Despite their benign nature, venous invasion, a rare occurrence in renal AMLs, poses management challenges. We present a case of bilateral renal AML in a 52-year-old female with a right renal vein and hepatic inferior vena cava invasion.

A Rare Case of Transplanted Kidney Lymphangiectasia in a Patient With Joubert Syndrome.

Renal lymphangiectasia is one of the rarest surgical complications in post-transplant kidney patients. A few patients may clinically complain of nonspecific symptoms, and the other few might be diagnosed incidentally. We report the case of a 32-year-old female patient with a known case of Joubert syndrome who presented with nonspecific clinical manifestations. The patient underwent ultrasound, magnetic resonance imaging (MRI), and nuclear medicine (NM) imaging to confirm the diagnosis, which showed radiologic features of renal lymphangiectasia. Conservative medical management was delivered to the patient.

Multifocal Nodular Fatty Sparing Mimicking Hepatic Tumors.

Hepatic steatosis is frequent; however, it may present with unusual patterns, resulting in a diagnostic dilemma. Herein, we present a case of fatty liver and multifocal nodular hepatic lesions that were found to be due to multifocal nodular fatty sparing, which mimics metastasis or primary multifocal tumors. As the differential diagnosis of such lesions can be difficult based on ultrasound alone, the knowledge of Magnetic Resonance Imaging (MRI) findings is crucial. It enables the radiologists to make the correct diagnosis and alleviate the patient from unnecessary biopsies.

Fat-Containing Renal Cell Carcinoma Mimicking Angiomyolipoma: A Radiological and Histopathological Diagnostic Challenge.

A well-marginated fat-containing renal lesion gives strong suspicion of renal angiomyolipoma (RAML) that usually requires no surgical intervention. Radiologically, renal masses with a large amount of fat can rule out renal cell carcinoma (RCC). Calcifications are very infrequent in RAML. However, the presence of calcifications in a fat-containing renal lesion is highly suggestive of RCC. These lesions should undergo surgical resection and histopathological assessment to reach the right diagnosis and avoid poor outcomes if diagnosed late. We present a case of bilateral renal tumors, in which one of them radiologically contained abundant fat with calcifications on CT scan, which was confirmed to be an RCC on histopathological examination.

MRI of failed total hip replacement caused by abductor muscle avulsion.

OBJECTIVE: Our purpose is to describe the use of MRI and associated metal artifact reduction techniques to detect abductor muscle avulsion from the greater trochanter, a complication unusual to the anterolateral approach for total hip replacement. CONCLUSION: MRI facilitates the detection of abductor muscle avulsion in patients who have undergone the anterolateral approach during total hip replacement. MRI is considered a valuable diagnostic tool when this condition is suspected.
