adrenal cyst

Introduction

Introduction to adrenal cysts The size of adrenal cysts can range from a few millimeters to more than 20 centimeters, mostly unilateral, and bilateral cysts account for 8% to 10%. Most of the clinical asymptomatic, for the accidental discovery, a small number of large adrenal cysts can produce compression symptoms. When the adrenal cyst is large, it may cause non-specific symptoms such as waist and abdomen pain and gastrointestinal discomfort due to compression of surrounding organs. A small number of patients may cause acute abdomen due to cyst rupture and hemorrhage. basic knowledge The proportion of sickness: 0.01% Susceptible people: no specific population Mode of infection: non-infectious Complications: Adrenal tumors Adrenal crisis

Cause

Causes of adrenal cysts

Adrenal cysts are divided into four pathological types: (1) Endothelial cysts: 45%, divided into lymphoma and hemangioma, and the lining of the wall is characterized by smooth and flat endothelial cells. (2) pseudocyst [2]: 39%, mainly due to adrenal tissue or intratumoral hemorrhage, can also be caused by cystic degeneration of the tumor, the wall of the capsule consists of dense fibrous tissue, no epithelial lining. Scholars believe that the most common pseudocyst in the clinic. (3) Epithelial cysts: 9%, including embryonic cysts, adrenal cystadenoma, true or retention cysts, and the inner wall is lined with glandular epithelial cells. (4) parasitic cysts: 7%, the most common with echinococcosis cysts, showing wall thickness, multiple calcification, and visible head section.

Prevention

Symptom

First, abdominal mass: This is also an important factor in judging renal cysts. As the cysts are exposed to the kidneys, the kidneys have problems, the kidney function is weakened, and the larger the cysts, the worse the function of the kidneys.

Adrenal cysts second, high blood pressure: Because the cyst squeezes the kidneys, the kidneys will develop ischemia, which leads to an increase in the amount of renin secretion, which causes an increase in blood pressure. About 50% of patients will develop hypertension. .

Third, the waist, abdominal pain and pain: Because of the expansion and enlargement of the kidney tumor, the tension of the kidney capsule is increased, causing the organs around the kidney to be squeezed and painful. In addition, the cyst is filled with a lot of water, and the sagging also makes Or if it is abdominal pain, it is characterized by dull pain, dull pain, and colic.

Fourth, hematuria: hematuria is also a major symptom of renal cysts, hematuria can be divided into microscopic hematuria and gross hematuria, and hematuria often presents periodicity. Hematuria occurs due to the presence of a large number of arteries under the patient's cyst, which are ruptured by some pulling or squeezing and blood is flowing into the urine.

Examine

Examination of adrenal cysts

1. For <3cm, cysts without clinical symptoms and without endocrine function may not be treated.

2, for the symptoms of tumor compression, cyst diameter > 5cm or hydatid cysts, tumor cysts, once found, need early surgical treatment.

3, for asymptomatic, simple cysts <4cm in diameter, can continue to observe clinically, such as increased or symptomatic surgery.

Diagnosis

Diagnosis and identification of adrenal cysts

Except for a small number of tumor-derived adrenal cysts, adrenal cysts do not affect adrenal function, and there are no abnormal changes in laboratory tests. Therefore, the diagnosis of adrenal cysts mainly relies on imaging examination. If the cysts are small, the diagnosis is more difficult, but for comparison. Large cysts, whether by color Doppler ultrasound or CT examination, may be confused with cystic lesions of surrounding organs such as hepatic cysts [4], renal cysts and pancreatic cysts. Moreover, adrenal cysts are rare lesions that are easily ignored by doctors and are one of the causes of misdiagnosis. Therefore, for the posterior retroperitoneal cystic lesions should also consider whether it is derived from the adrenal gland, ultrasound is the preferred means of examination, economical painless safety, and can greatly improve the diagnosis rate, but also provide patients with the best time for diagnosis and treatment.
