Patient presents with complaints possibly indicative of a right renal cyst.  Symptoms, if present, may include flank pain, hematuria, or hypertension, though right renal cysts are often asymptomatic and discovered incidentally during abdominal imaging for unrelated reasons.  Physical examination findings are typically unremarkable.  Differential diagnoses include renal neoplasm, renal abscess, and other cystic renal lesions.  Imaging studies, such as abdominal ultrasound, CT scan of the abdomen and pelvis without contrast, or MRI of the abdomen, were performed to evaluate the right kidney.  The imaging revealed a simple renal cyst on the right kidney, demonstrating characteristic features such as a smooth, thin wall, anechoic fluid content, and posterior acoustic enhancement on ultrasound, or a well-circumscribed, homogeneous, low-attenuation lesion without contrast enhancement on CT.  Based on the imaging characteristics, the diagnosis of a benign simple right renal cyst is confirmed.  No evidence of complex features, such as septations, calcifications, or solid components, suggesting malignancy, were observed.  The patient was counseled on the benign nature of simple renal cysts and provided with information regarding observation and follow-up.  No specific treatment is indicated at this time, as the cyst is asymptomatic and uncomplicated.  Patient education included discussion of symptoms to monitor for, such as persistent pain, fever, or hematuria, which would warrant further evaluation.  Follow-up imaging may be considered in the future if clinically indicated.  ICD-10 code N28.1, right renal cyst, is documented for billing and coding purposes.
