Fortuitous findings of Tc-99m PIPIDA hepatobiliary scintigraphy.

Hepatobiliary scintigraphy using Tc-99m labeled radiopharmaceuticals is employed primarily for the diagnosis of acute cholecystitis and for demonstration of biliary tract potency. This produce may also provide diagnostic information in the identification of unusual or atypical hepatobiliary disorders; frequently, this occurs as an incidental result of the test. We present five cases in which trauma, infection, or obstructive abnormalities were diagnosed fortuitously.

Treatment of medullary carcinoma of the thyroid with I-131.

We present a patient with radioiodine concentration in pulmonary metastases presumably arising from medullary carcinoma of the thyroid. Transient symptomatic improvement occurred after treatment with a large dose of sodium iodide (I-131). Although radioiodine concentration in medullary carcinoma of the thyroid is rare, the findings in this patient and in other recent reports suggest that an attempt should be made to determine whether a medullary carcinoma concentrates radioiodine. If so, I-131 treatment might be beneficial.

Cholescintigraphy: gallbladder nonvisualization secondary to neoplasm.

Whereas the diagnosis of acute cholecystitis is characterized by nonvisualization of the gallbladder with Tc-99m iminodiacetic acid derivatives, nonvisualization is not specific for acute cholecystitis. The first reported case of nonvisualization of the gallbladder due to neoplasm is added to an expanding list of causes of nonvisualization other than the more frequent causes: acute and chronic cholecystitis.

99mTc-PIPIDA cholescintigraphy in the diagnosis of gallbladder disease.

The efficacy of 99mTc cholescintigraphy in the diagnosis of gallbladder disease was studied in 116 patients. Sixty-one demonstrated gallbladder visualization (normal) and 55 had nonvisualization. In patients with acute abdominal pain, test sensitivity is 100%, specificity is 77%, and accuracy is 83% for the diagnosis of acute cholecystitis; no patient with gallbladder visualization had acute cholecystitis. Test sensitivity for any form of gallbladder disease is 66%, specificity is 82%, and accuracy is 71%; excluding patients with laboratory evidence of hepatobiliary disease, the predictability of acute or chronic cholecystitis increases to 100%. Cholescintigraphy demonstrated common bile duct patency in all eight post-cholecystectomy patients referred for evaluation of possible choledocholithiasis. Thus, gallbladder visualization with 99mTc-PIPIDA virtually excludes the diagnosis of acute cholecystitis, an abnormal test is a good predictor of gallbladder disease because of high specificity, and cholescintigraphy is extremely safe and simple to perform and may be used to demonstrate common bile duct patency.

Computed tomography in acquired absence of thoracic pedicle.

A patient with an acquired absence of a thoracic pedicle is presented, and the contribution of CT examination is demonstrated. A brief anatomical and radiographic review of congenital and acquired absence of pedicles is provided.
