Teach you how to identify hamartoma

Since hamartoma is not a common disease, many people do not have basic knowledge about this disease. Once they suffer from hamartoma, they have no way to identify it, let alone timely treatment. Therefore, we should learn more about various diseases in life. The following article will teach you how to identify hamartoma.

Differential diagnosis of renal hamartoma

1. Renal cell carcinoma

It also manifests as low back pain, lumbar and abdominal masses and hematuria, but painless intermittent macroscopic hematuria is more obvious. Lumbar and abdominal masses are often discovered late. Shock and acute abdomen caused by tumor rupture and bleeding are very rare. Ultrasound examination often shows low echo or uneven echo. Renal artery angiography can show enlarged renal shadow and contrast agent accumulation in the parenchymal phase. IVU shows that the renal pelvis and calyces are mostly destroyed. CT can show uneven density in the kidney, irregular edges, and a substantial mass that is unclearly demarcated from the surrounding normal tissue. The CT value of the mass is slightly lower than that of normal renal parenchyma. Enhanced scanning shows that the CT value of the mass is higher than that of normal renal parenchyma.

2. Wilms tumor

Its main clinical manifestation is also a progressively enlarging abdominal mass, but it mostly occurs in children. The disease progresses rapidly and is accompanied by cachexia. Ultrasound examination shows small scattered low-echo spots, and IVU shows obvious destruction or loss of the renal pelvis and calyces.

3. Polycystic kidney disease

Low back pain and lumps in the waist and abdomen are similar to this disease, but the disease progresses slowly, and hematuria, hypertension and renal function impairment are more obvious. IVU shows enlarged kidneys with irregular edges, elongated and deformed calyces. Ultrasound examination shows multiple round anechoic dark areas in the renal parenchyma. CT examination shows enlarged kidneys, and numerous cystic masses of varying sizes with smooth edges can be seen in the renal parenchyma.

4. Rupture of intra-abdominal solid organs

Symptoms include sudden abdominal pain, rebound tenderness and abdominal muscle tension, and shock due to severe bleeding. It is easy to be confused with spontaneous rupture and bleeding of renal hamartoma. However, there is a primary organ lesion before the bleeding, such as liver cancer. Trauma or strenuous activity is often the cause of rupture and bleeding. There is no hematuria. IVU shows normal morphology of renal pelvis and calyces, and ultrasound examination of the kidneys shows normal sound and image.
