Right adrenal tumors can be divided into functional and non-functional tumors. Functional tumors are common in pheochromocytoma, and non-functional tumors often include neuroblastoma and ganglion cell neuroma. 1. Pheochromocytoma: Hypertension is the hallmark manifestation of the disease, which can be categorized into paroxysmal, persistent or continuous hypertension paroxysmal exacerbation. There are also metabolic disorders leading to elevated blood glucose and decreased glucose tolerance. Larger tumors may be palpable as a mass in the abdomen. Diagnosis can be made by CT, ultrasound and MRI. Surgery is the only effective treatment for this disease. 2. Neuroblastoma: The most common symptom is lumps in different parts of the body, and the common parts are abdomen and chest cavity. In addition, patients may have paroxysmal high blood pressure, palpitation (rapid heartbeat, often accompanied by panic), flushing and other symptoms in the late stage. 3. Ganglion cell neuroma: the main symptom is local mass, the symptom is hidden, only when the tumor grows up, there will be corresponding compression symptoms. It can be diagnosed by ultrasound, CT and biopsy. For the diameter <3cm tumors are usually not treated, and only tumors >3cm are treated surgically. For patients diagnosed with right adrenal tumor, they should go to relevant departments of regular hospitals as soon as possible, and under the guidance of professional physicians, in order to avoid delaying the condition and leading to adverse consequences.
