INCIDENTALOMA - WHAT IT IS ?
Definition :- Tumor found by coincidence (incidentally) without
clinical symptoms or suspicion .
Definition excludes :- Patients undergoing imaging procedures as a part of staging &
workup for cancer.
With increase of “whole – body CT scanning “ as a part of screening programs – incidence of incidentaloma expected to increase.
37% patients receiving whole body CT scan may have abnormal findings which need further evaluation.
INCIDENCES
Up to 20-50% of mediastinal tumors are detected incidentally.
Most of the Solitary Pulmonary Nodules are incidentally detected ( 0.2% of chest X-rays images).
According to the American Cancer Society, lifetime odds to develop lung cancer –
1 in 13 – men 1 in 16 – woman
Of these between 20% and 30% will present as an Solitary Pulmonary Nodule.
Master Health Check up at patient request
Carefully studied routine investigations – probably essential to pick some life threatening conditions at early ( probably curable ) stage .
HOW WE DETECTED….
Study period :- February 2008 to July 2013
We reviewed the record of the patients retrospectively.
Asymptomatic and Routine Master Health Checkup
As part of pre employment
As part of requirement for VISA

SIGNIFICANCE OF DETECTING AND ??? MANAGEMENT
For Patients :- Potentially lethal conditions can be diagnosed
early. Can be treated with curative intent Decreases the morbidity Improves outcome and survival.
For Doctors :- Medico –Legal consequences
WHAT DO I MEAN ?
Medico – Legal consequences ……
A 44-year-old female received a routine chest X-ray prior to hernia surgery; an incidental finding of a lung nodule was not reviewed by the ordering clinician, and was never followed up, resulting in a delayed cancer diagnosis and a poor prognosis
Allegation
The patient’s estate sued the surgical resident and the hospital, alleging that negligent failure to act upon an abnormal chest X-ray resulted in a three-year delay in diagnosing the cancer. The suit claimed that the delay allowed a potentially very treatable/curable cancer to advance to a terminal stage for this patient.
Disposition
This case settled for more than $2 million against the hospital and the surgical resident.
CONCLUSION
Routine full body health check up’s may not necessarily be unnecessary.
Even the tiniest of the lesion can be devastating if not addressed appropriately
