Radiation Pneumonitis	D017564	[Inflammation of the lung due to harmful effects of ionizing or non-ionizing radiation.]
Radicular Cyst	D011842	[Slow-growing fluid-filled epithelial sac at the apex of a tooth with a nonvital pulp or defective root canal filling.]
Radiculopathy	D011843	[Disease involving a spinal nerve root (see SPINAL NERVE ROOTS) which may result from compression related to INTERVERTEBRAL DISK DISPLACEMENT; SPINAL CORD INJURIES; SPINAL DISEASES; and other conditions. Clinical manifestations include radicular pain, weakness, and sensory loss referable to structures innervated by the involved nerve root.]
Radiodermatitis	D011855	[A cutaneous inflammatory reaction occurring as a result of exposure to ionizing radiation., Acute skin manifestations at the site of previous exposure to ionizing radiation. It is triggered by the administration of certain drugs days or years after the initial radiation exposure.]
Radius Fractures	D011885	[Fractures of the RADIUS.]
Ranula	D011900	[A form of retention cyst of the floor of the mouth, usually due to obstruction of the ducts of the submaxillary or sublingual glands, presenting a slowly enlarging painless deep burrowing mucocele of one side of the mouth. It is also called sublingual cyst and sublingual ptyalocele.]
Rare Diseases	D035583	[A large group of diseases which are characterized by a low prevalence in the population. They frequently are associated with problems in diagnosis and treatment., Rare diseases that have not been well studied.]
Rat-Bite Fever	D011906	[A syndrome characterized by recurring fever, rash, and arthralgias occurring days to weeks after a rat bite. The causative agents are either Streptobacillus moniliformis or Spirillum minus.]
Raynaud Disease	D011928	[An idiopathic vascular disorder characterized by bilateral Raynaud phenomenon, the abrupt onset of digital paleness or CYANOSIS in response to cold exposure or stress.]
Rectal Diseases	D012002	[Pathological developments in the RECTUM region of the large intestine (INTESTINE, LARGE).]
Rectal Fistula	D012003	[An abnormal anatomical passage connecting the RECTUM to the outside, with an orifice at the site of drainage.]
Rectal Neoplasms	D012004	[Tumors or cancer of the RECTUM.]
Rectal Prolapse	D012005	[Protrusion of the rectal mucous membrane through the anus. There are various degrees: incomplete with no displacement of the anal sphincter muscle; complete with displacement of the anal sphincter muscle; complete with no displacement of the anal sphincter muscle but with herniation of the bowel; and internal complete with rectosigmoid or upper rectum intussusception into the lower rectum.]
Rectocele	D020047	[Herniation of the RECTUM into the VAGINA.]
Rectovaginal Fistula	D012006	[An abnormal anatomical passage between the RECTUM and the VAGINA.]
Recurrence	D012008	[The return of a sign, symptom, or disease after a remission.]
Recurrent Laryngeal Nerve Injuries	D061226	[Traumatic injuries to the RECURRENT LARYNGEAL NERVE that may result in vocal cord dysfunction.]
Red-Cell Aplasia, Pure	D012010	[Suppression of erythropoiesis with little or no abnormality of leukocyte or platelet production.]
Refeeding Syndrome	D055677	[A condition of metabolic imbalance that is caused by complications of initially feeding a severely malnourished patient too aggressively. Usually occurring within the first 5 days of refeeding, this syndrome is characterized by WATER-ELECTROLYTE IMBALANCE; GLUCOSE INTOLERANCE; CARDIAC ARRHYTHMIAS; and DIARRHEA.]
Reflex Sympathetic Dystrophy	D012019	[A syndrome characterized by severe burning pain in an extremity accompanied by sudomotor, vasomotor, and trophic changes in bone without an associated specific nerve injury. This condition is most often precipitated by trauma to soft tissue or nerve complexes. The skin over the affected region is usually erythematous and demonstrates hypersensitivity to tactile stimuli and erythema.
