The purpose of this study was to aid in diagnosis of salivary gland disease by comparing the sialogram with the scintigram. In this study, 47 patients (52 glands) who had taken the sialography and the scintigraphy were examined. The result of two methods was compared with the clinical and operative diagnosis. The following results are obtained. 1. In inflammatory diseases of the salivary gland, the scintigraphy can be a valuable substitution for a sialography. 2. In inflammatory diseases of the salivary gland, we can get more informations in case of the combined use of the sialography and the scintigraphy. 3. In tumorous lesion of the salivary gland, the sialography is superior to the scintigraphy. But both methods are less valuable in diagnosing the extraglandular tumors.

Gallium-67 scintigraphy is helpful in the assessment of active extrapulmonary sarcoidosis. Muscular involvement of sarcoidosis is often asymptomatic or nonspecific, and laboratory examinations do not provide convincing evidence of muscular involvement We report a case of muscular sarcoidosis, which was detected by gallium-67 scintigraphy. In a patient who was suffering from fever and arthralgia of knee joint, gallium-67 scintigraphy showed mediastinal and hilar involvement of sarcoidosis with unexpected extensive muscular uptake. Magenetic resonance imaging revealed the detailed depiction of intramuscular infiltration of sarcoid granuloma. Gallium-67 scintigraphy is useful in detecting inflammatory muscular involvement of sarcoidosis as well as other multiorgan involvement.

In Graves' disease, changes in orbital tissue and structure are casued by inflammatory infiltation, which induces increase of capillary permeability and breakdown of blood-tissue barriers. Using the uptake of $^{99m}Tc-DTPA$ in inflammatory lesion, Eye/Brain radioactivity ratios in brain scintigraphy were evaluated in 15 normal controls and 40 Graves' patients. The results were as follows; 1) Eye/Brain radioactivity ratio was significantly higher in Graves' ophthalmopthy group than in control group (p < 0.005). 2) In Graves' ophthalmopathy, Eye/Brain radioactivity ratio was significantly higher in active (progressive) group than in inactive (non-progressive) group (p < 0.05). 3) There was no correlation between class of ATA classification of Graves' ophthalmopathy and Eye/Brain radioactivity ratio. 4) There was no correlation between Eye/Brain radioactivity ratio and serum activity of TBII. In conclusion, Eye/Brain radioactivity ratio using $^{99m}Tc-DTPA$ brain scintigraphy may be useful to determine the activity of Graves' ophthalmopathy and whether treatment of Graves' ophthalmopathy is necessary or not.

Ga-67 scintigraphy demonstrated increased uptake in the lungs and stomach in a 26-year-old man with hypercalcemia. A primitive neuroectodermal tumor was confirmed by bone marrow examination. Tc-99m MDP uptake in the same locations as Ga-67 revealed by bone scintigraphy was consistent with metastatic calcification. Although the mechanism of Ga-67 uptake in metastatic calcification is not understood, the presence of an inflammatory process is suggested.

Hypertrophic pulmonary osteoarthropathy classically consists of clubbing of the fingers and toes, periosteal new bone formation in the tubular bones, painful swelling of limbs, arthralgia and arthritis. Its pathogenesis is uncertain, but it is usually associated with malignant or inflammatory intrathoracic disease. We recently experienced a patient with the characteristic findings of this rare disease on bone scintigraphy using $^{99m}Tc-MDP$(methylene diphosphonate).

Computed tomography (CT) seems to be the best imaging modality to diagnose an enterovesical fistula, but is not always able to demonstrate enterovesical fistula itself. In this case report, we present Tc-99m HMPAO white blood cell (WBC) scintigraphic findings of an enterovesical fistula complicating Crohn's disease. A 22 year-old male presented with a one-month history of urinary symptoms such as dysuria, hematuria, and frequency. The patient had intermittent right lower quadrant pain, diarrhea and hematochezia. Enterovesical fistula was highly suggestive in pelvic CT which showed air density in the urinary bladder, but cystoscopy failed to find an opening of the fistula. Tc-99m HMPAO WBC scintigraphy for evaluation of inflammatory bowel disease incidentally demonstrated enterovesical fistular tract. Crohn's disease was later confirmed by histologic examination of the surgical specimen. In our patient, Tc-99m HMPAO WBC imaging was helpful in determining the location of the fistula as well as assessing the disease activity and extent of the Crohn's disease.

Recently ultrasound and scintigraphic study are most useful modality for diagnosis of scrotal diseases. They are able to determine the nature, anatomic extent of the lesion, and possible to differential diagnosis of the scrotal lesion. The ultrasound and scintigraphic findings were analyses in 59 patients of confirmed scrotal disease at Seoul Red Cross Hospital from June 1986 to Aug. 1989. The results were as follows. 1) Most patients were below the 30 years old age (69.4%), and most prevalent age was $11\sim30$ Yrs. in trauma, $31\sim40$ Yrs. in inflammation, and $51\sim60$ Yrs. in mass lesion of scrotum. 2) The diagnostic accuracy of scrotal disease was 94.9% in ultrasound and 72% in scintigraphic study. The ultrasound study showed high accuracy in all kind of scrotat disease, but scintigraphy showed only high detection rate in inflammatory disease. 3) Scrotal ultrasound is first choice of study for the diagnosis of scrotal lesion, and useful determine the cystic or solid lesion and anatomic extent of disease. However it can't be differentiate the acute epididymitis with acute testicular torsion. 4) Scrotal scintigraphy is useful study for the diagnosis of acute painful scrotal disease, and showed specific findings in acute epididymitis and acute torsion for differential diagnosis. 5) In consideration of age, history and clinical findings of patient, appropriate study will be chosen firstly in ultrasound and scintigraphy, and combined all of findings of these studies will be helpful for the accurate diagnosis and adequate treatment of scrotal disease.

Sjogren's syndrome is a chronic inflammatory disease that predominantly affects salivary, lacrimal and other exocrine glands. We report a case of Sjogren's syndrome combined with MALT (mucose associated lymphoid tissue) lymphoma which occured in the parotid gland. A 57-year-old female with the complaint of painful swelling and lymph node enlargement was referred to our department. Sialograms of both parotid glands showed globular collections of contrast material uniformly distributed throughout the parotid gland. Salivary scintigraphy showed decreased uptake of the parotid gland. CT scan showed larger, slightly more dense parotid gland than normal and honeycomb glandular appearance. Also, It showed discrete, slightly more enhanced round mass in the left parotid gland. Histopathological finding showed replacement of salivary gland parenchyma with dense small lymphocytic infiltration having the feature of epimyoepithelial islands. Kappa light chain restriction of interglandular plasma cell could be seen.

Sternocostoclavicular hyperostosis (SCCH) is a chronic, nonsuppurative inflammatory disease involving sternum, clavicle, upper ribs and its adjacent soft tissue. It is a relatively newly described syndrome, characterized by ossification in the region between the clavicle and the first rib, and hyperostosis of the medial end of the clavicle with simultaneous involvement of the sternum and juxtasternal ribs. We experienced one case of sternocostoclavicular hyperostosis, diagnosed by pinhole bone scintigraphy. This paper describes characteristic pinhole scintigraphic findings of SCCH, with comparative study with radiographic and pathologic findings.

Juvenile dermatomyositis is a common inflammatory muscle disease of childhood, characterized by weakness in proximal muscles and specific skin rash. In case of juvenile dermatomyositis without characteristic clinical features, non-invasive imaging tools such as $^{99m}Tc$-HDP three-phase bone scan are very helpful in diagnostic workup of myopathies. We report a case of 13-year old female with juvenile dermatomyositis, in which $^{99m}Tc$-HDP three-phase bone scan was useful in diagnosis and assessing therapy response.
