Bottom Line: A total of 253 IFs were found in 241 patients (18.8% of 1278).Extraspinal IFs are commonly detected during a routine lumbar MRI, and many of these findings are not clinically significant.However, IFs including clinically important findings are occasionally omitted from formal radiological reports.

ABSTRACT

Objective: The aim of the present study was to determine the prevalence and reporting rate of incidental findings (IF) in adult outpatients undergoing lumbar magnetic resonance imaging (MRI).

Materials and methods: Re-evaluation of a total of 1278 lumbar MRI images (collected from patients with a mean age of 50.5 years, range 16-91 years) captured between August 2010-August 2011 was done by a neuroradiologist and a musculoskeletal radiologist. IFs were classified according to organ or system (liver, gallbladder, kidney, bladder, uterus, ovary, lymph node, intestine and aorta). The rate of reporting of a range of IF was examined. The outcome of each patient's treatment was evaluated based on review of hospital records and by telephone interviews.

Results: A total of 253 IFs were found in 241 patients (18.8% of 1278). Among these, clinically significant IFs (n = 34) included: 2 renal masses (0.15%), 2 aortic aneurysms (0.15%), 2 cases of hydronephrosis (0.15%), 11 adrenal masses (0.86%), 7 lymphadenopathies (0.55%), 6 cases of endometrial or cervical thickening (0.47%), 1 liver hemangioma (0.08%), 1 pelvic fluid (0.08%) and 2 ovarian dermoid cysts (0.15%). Overall, 28% (71/253) of IFs were included in the clinical reports, while clinically significant findings were reported in 41% (14/34) of cases.

Conclusion: Extraspinal IFs are commonly detected during a routine lumbar MRI, and many of these findings are not clinically significant. However, IFs including clinically important findings are occasionally omitted from formal radiological reports.

Mentions: The presence of a renal mass was detected in two cases. In one of the patients, the positron emission tomography (PET) examination revealed a mass in the lung and brain metastasis and one month later the patient died. Meanwhile, nodular lesion in the retroperitoneal area was detected in the other case (Fig. 3) and this patient had 2 IFs. The hospital records contained no record of the surgical intervention in this case and the patient could not be reached by phone.
