1/15. Large bilateral star-shaped calculi in the seminal vesicles.

    calculi in the seminal vesicles (SV) are extremely rare. A patient having large bilateral star-shaped calculi in the SV is reported. They were seen on plain x-ray and confirmed by computed tomography. On the reconstructed CT scans the large stone on the right side measured about 35 X 35 X 50 mm and the one on the left, 30 X 20 X 45 mm. They were not felt on rectal examination, as they were situated laterally.

2/15. Resolution of ephedrine stones with dissolution therapy.

    A patient with a history of ingesting large quantities of an over-the-counter stimulant developed renal calculi that on further analysis, after stone passage, revealed increased amounts of ephedrine. Over the course of 7 months, all of the patient's ephedrine stones were managed successfully by alkalinization. Similar to previously reported ephedrine calculi, these stones were radiolucent on x-ray imaging, but their course was monitored on serial nonenhanced computed tomography scans. We believe this to be the first reported use of alkaline therapy for the dissolution of renal stones containing ephedrine.

3/15. Pulmonary alveolar microlithiasis: a report on four cases.

    The accidental discovery of a diffuse but sharply defined micro-nodular pattern on routine chest x-ray of an asymptomatic patient makes the diagnosis of pulmonary alveolar microlithiasis more likely whereas the finding of different sized microliths that are located in alveolar spaces, in a lung biopsy specimen, confirm the diagnosis. Four cases are reported in this context.

4/15. Uterine lithiasis.

    We report a case of uterine lithiasis in a 73-year-old Latin American woman. The patient underwent vaginal hysterectomy and colporrhaphy for complaints related to secondary uterine prolapse and cystocele. The 70-g, 8 x 5 x 3.5 cm uterus had a normal shape. Ten white, starlike, 0.5 x 0.5 x 0.2 cm, calcified structures were found within the endometrial cavity. Chemical analysis of one of these by x-ray diffraction showed it to be composed of calcite, one of the crystalline forms of calcium carbonate. To our knowledge, this is the first report of human uterine lithiasis in the literature.

5/15. Extracorporeal piezoelectric shockwave lithotripsy of multiple pancreatic duct stones under ultrasonographic control.

    The first ultrasonographically controlled fragmentation of multiple pancreatic duct stones of up to 14 mm size by means of extracorporeal, piezoelectric shockwave lithotripsy is reported. On account of the ultrasound localization and continuous control during therapy a nasopancreatic tube for instillation of contrast medium and frequent x-ray checks were not necessary. The 48-year-old patient did not experience any pain during the four treatment sessions and during the follow-up period. No complications were noted.

6/15. Buccal hemangioma with phleboliths. Report of two cases.

    Two cases of buccal hemangioma with phleboliths were reported. angiography, angioxerography, and computerized tomography were carried out before the procedures were planned. One patient was treated by means of surgical excision of the tumor after ligation of the left external carotid artery. The second patient was treated by means of surgical excision alone. Histologic examinations suggested that the thrombi in the blood vessels of hemangiomas might become the core of the phleboliths. Analysis of the phleboliths by means of x-ray diffraction and infrared spectrometry confirmed calcium phosphate and calcium carbonate as the main components of the phleboliths.

7/15. Mucoid impaction (inspissated secretions) in segmental bronchial obstruction.

    Localized persistent mucoid impaction as seen on the chest radiograph is a fairly common roentgen finding that always implies segmental bronchial obstruction. Collateral ventilation apparently permits air to enter the lung distal to the obstruction, outlining bronchi distended with trapped mucus or other secretions. This mucoid impaction sign has been seen in a variety of obstructing conditions, including primary and metastatic carcinoma of the lung, bronchial adenoma, tuberculous bronchostenosis, bronchial adenoma, tuberculous bronchostenosis, broncholithiasis, bronchial atresia, sequestration, pulmonary bronchogenic cyst, and foreign body. The roentgen appearance of the impacted mucus is variable, depending to a considerable degree on its orientation in relation to the direction of the x-ray beam. The presence of unexplained localized mucoid impaction is an indication for immediate study to demonstrate or exclude an obstructing bronchial lesion.

8/15. Calcification of basal ganglia and cerebellar roof nuclei in mentally defective patient with hidrotic ectodermal dysplasia. Analysis of intracranial concretions by electon microprobe.

    This report describes, for the first time, an analysis by electron microprobe of concretions in the brain of an individual with striopallidodentate calcification. We also report the unique association of this intracranial syndrome with hidrotic ectodermal dysplasia. An institutionalized male with impaired intellectual function and hidrotic ectodermal dysplasia was known since the age of 3 years to have bilateral radiopaque densities in the region of the basal ganglia on skull roentgenogram. He died at age 29 in congestive heart failure from rheumatic pancarditis. At autopsy, concretions were identified in globus pallidus, caudate nuclei, thalamus, and dentate nuclei. Mineral deposits within the brain, analyzed by energy dispersive x-ray microanalysis, consisted predominately of calcium and phosphorus. Trace amounts of magnesium, iron, and silicon also were detected.

9/15. Vaginal calculus in female with myelodysplasia.

    A case report of vaginal calculus formation in a nine-year-old girl with myelodysplasia is presented. Etiologic factors in the formation of such calculi include fistulous communication between the vagina and the bladder, neuropathic urethrovesical dysfunction, anatomic conditions causing vaginal outlet obstruction, and/or vaginal pooling of urine and urease-producing bacterial infection. A correct preoperative diagnosis can be made by using oblique x-ray films and cystoscopy. Surgical treatment is simple and successful.

10/15. Bone scintigraphy in pulmonary alveolar microlithiasis: a comparative study of radioactivity and density distribution.

    A histologically proven case of pulmonary alveolar microlithiasis that demonstrated intense lung uptake of Tc-99m-MDP on a bone scan is presented. The spatial distribution within the lungs of the radioactivity and density was assessed either by single photon emission computed tomography (SPECT), or x-ray computed tomography (CT) respectively, and the regional magnitude of the two parameters were compared. The quantitative study of regional radioactivity and density revealed that both the parameters distributed symmetrically, showing gradual increase in magnitude from the upper to the lower lung regions. The radioactivity-density association observed in our patient may indicate on-going formation of microcalculi throughout the lungs, the degree of which is greater at the sites of more severe involvement.
