RESUMEN
Hydatic disease caused by Echinococcus granulosus is an endemic disease and an important public health problem in some countries of the world. The results of surgical treatment are associated with a high rate of mortality, morbidity, postoperative recurrence and a long period of hospital stay and the medical treatment results are still controversial. Although the percutaneous aspiration and treatment of liver hydatid cysts were considered to be contraindicated due to risks of anaphylactic shock and dissemination of clear-crystal fluid into the abdomen, several reports of successful percutaneous treatment of liver hydatid cysts have been published in the literature. Today, percutaneous treatment of liver hydatid cysts is the most effective and reliable treatment procedure in the selected cases. In this review, indications, contraindications, method and techniques, healing criteria, complications, results and importance of the percutaneous treatment of liver hydatid cysts are discussed.

Duplication of the gallbladder, a rare congenital anomaly, is important in clinical practice because it may cause some clinical, surgical, and diagnostic problems. We present imaging findings of a double gallbladder including coronal reformatted computed tomographic sections, to our knowledge not previously presented, and discuss the radiologic signs that may be helpful in diagnosis. We also present another case of a double gallbladder in which only one gallbladder was imaged 10 years after cholecystectomy.

OBJECTIVE: To determine the interobserver and intraobserver variations in sonographic measurement of thyroid volume in children. DESIGN: Thyroid volumes of 30 healthy children were measured by three separate observers. Additionally each observer measured thyroid volumes of ten separate children three times. METHODS: The data were used to assess intraobserver and interobserver variations in measurement of thyroid volume. Interobserver and intraobserver variations in measuring each diameter of the thyroid gland were also determined. The effect of thyroid size on interobserver and intraobserver variations was analyzed. RESULTS: Intraobserver variation in measurement of thyroid volume was 8.4+/-6.7% (mean+/-s. d.). Interobserver variation was 13.3+/-8.2%. The widest interobserver variation was encountered in determining the craniocaudal diameter of the thyroid gland. No correlation was found between thyroid volume and interobserver variation (r=-0.12, P=0.27), whereas a slight but statistically significant correlation was found between thyroid volume and intraobserver variation (r=-0.26, P=0.012). CONCLUSION: Significant interobserver and intraobserver variation occurs in sonographic measurement of thyroid volume in children.

OBJECTIVE: The purpose of this study was to determine the diagnostic value of diuretic duplex Doppler sonography in distinguishing between obstructive and nonobstructive hydronephrosis in children by calculating the resistive indices (RI) before and after administration of furosemide. MATERIAL AND METHODS: We prospectively evaluated 28 kidneys (2 solitary) in 15 patients with unilateral or bilateral neonatal hydronephrosis. All patients underwent diuretic renography and duplex Doppler sonography before and after administration of furosemide. RESULTS: According to the half-time drainage patterns at diuretic renography, 13 kidneys were classified as nonobstructed and 15 as obstructed. At baseline, the mean RI values of nonobstructed and obstructed kidneys were not significantly different (0.66 and 0.64, respectively). Ten minutes after the injection of furosemide, the mean RI values of the nonobstructed and obstructed kidneys were 0.68 and 0.70, respectively. The increase in RI over the baseline 10 min after the diuretic injection was statistically significant (p<0.00001) in the obstructed kidneys. CONCLUSION: The baseline RI value of 0.70 is not a definite value for distinguishing obstructed from nonobstructed systems. An increase in RI of at least 10% over the baseline seems to be a more reliable criterion, especially when it is used in conjunction with diuretic renography.

A small, fibrotic, and even calcified spleen is the hallmark of homozygote sickle cell disease in adults. Such a condition is very rare in sickle-thalassemia and, to our knowledge, not previously reported in a sickle cell trait. We report two heterozygote sickle cell siblings with splenic calcifications, one sickle cell trait and one sickle-beta+-thalassemia, without any history suggestive of splenic vasooclusive-infarctive crisis.

Ascariasis is a well-known cause of acute cholangitis and cholecystitis; however, very rarely do worms penetrate and colonize the liver parenchyma. Here we present the unique radiological demonstration (US, CT and ERCP) of hepatobiliary ascariasis in which worm was first alive in the parenchyma of the liver and subsequently died and formed liver abscess.

PURPOSE: To describe the percutaneous treatment of an orbital hydatid cyst as an alternative approach to conventional surgery. METHODS: In a 21-year-old man with diplopia and right proptosis, radiologic studies disclosed a 25 x 25 x 20-mm purely cystic mass in the right retrobulbar area. Based on the presumptive diagnosis of hydatid cyst, the cyst was treated percutaneously under ultrasonographic guidance with aspiration, 15% hypertonic saline injection, and reaspiration without any complication. RESULTS: A substantial decrease in the size of the cyst was observed in the 3 months after treatment. Nine months after treatment, the shrunken cyst had a volume of only 0.5 ml, and the patient was asymptomatic. Twenty-one months after the procedure, the findings were consistent with those at 9 months of follow-up. CONCLUSION: Percutaneous treatment of orbital hydatid cysts, which is more satisfactory to both the patient and the physician, may be a safe and effective alternative to surgical extirpation.

Percutaneous treatment of a huge congenital splenic cyst in a 23-year-old man is presented. The cyst had been catheterized and drained two times within a 3-month period without injecting any sclerosing agent into the cavity. On the third attempt, catheter drainage and injection of alcohol into the cyst cavity were performed because of insufficient response to drainage alone. He was discharged symptom-free after the procedure. The cyst diminished in size considerably 9 months after the treatment with alcohol. The volume of the cyst was reduced from 5200 to 8 ml. Although percutaneous treatment of a congenital splenic cyst with tetracyclin has been reported, to our knowledge this is the first case of a congenital splenic cyst treated with alcohol as a sclerosing agent. Percutaneous treatment of splenic cyst can obviate the need for partial or total splenectomy and may be an alternative to surgical treatment.

We report a case of bilateral multilocular cystic adrenal masses in a neonate who demonstrated somatic hypertrophy and macroglossia, which are considered to constitute an incomplete form of Beckwith-Wiedemann syndrome (BWS). After surgical removal of the masses, histological study revealed benign hemorrhagic macrocysts with cortical cytomegaly. There was no evidence of tumor or adrenal apoplexia. Although very rare, association of unilateral hemorrhagic adrenal macrocysts with BWS has been reported before; this is the first case of bilateral benign adrenal macrocysts associated with BWS.

PURPOSE: To evaluate the ultrasonographic and CT findings of tuberculous peritonitis. MATERIAL AND METHODS: Ultrasonographic and CT findings of 11 patients with the ascitic type of tuberculous peritonitis were reviewed. RESULTS: All patients had ascites, and ultrasonography (US) demonstrated fine complete and incomplete mobile septations in 10 patients. In 5 of them, the ascites had a lattice-like appearance. Diffuse regular peritoneal thickening was detected in all patients by CT and in 10 patients by US. CT demonstrated infiltration of the greater omentum in 9 patients, whereas US showed omental thickening in only 5 patients. CONCLUSION: Peritoneal and omental thickening detected by CT and ascites with fine, mobile septations shown by US strongly suggest the ascitic type of tuberculous peritonitis. The 2 imaging modalities should be used together for accurate diagnosis of tuberculous peritonitis.

PURPOSE: To evaluate the long-term effectiveness of percutaneous treatment of liver hydatid cysts. MATERIALS AND METHODS: Thirty-one patients (19 female patients and 12 male patients; age range, 8-78 years; mean age, 41 years) with 57 liver hydatid cysts underwent percutaneous treatment. The cysts were treated with hypertonic saline (15% NaCl) and/or absolute alcohol. Sonographic and/or fluoroscopic guidance was used. RESULTS: Repeated sonography revealed a gradual decrease in cyst size. Volume reduction was 18%-99% (mean, 83%). With the disappearance of the fluid component, pseudotumor appearance occurred. In all treated cases, the cyst wall became irregular and thicker during follow-up. No mortality occurred. No abdominal dissemination was encountered during follow-up. Major complications were infection of the cavity, hypersensitivity reaction, and development of biliary fistula. One cyst recurred 11 months after primary drainage. CONCLUSION: Long-term results indicate that percutaneous treatment of liver hydatid cysts is an effective and safe method in selected cases.

Ascaris lumbricoides is the most common roundworm in warm and temperate areas. Although radiological features of Ascaris lumbricoides are well defined, there are only a few reports on the ultrasonographic findings of intestinal ascariasis. In our two patients with no acute abdominal symptoms, intestinal ascariasis was initially diagnosed by abdominal ultrasonography. In both patients, tubular structures in the segments of the small intestine were demonstrated by ultrasonography.

Hyperoxaluria is characterized by nephrocalcinosis and nephrolithiasis on radiological examination and may also result in diffuse deposition of calcium oxalate crystals in multiple extrarenal organs (oxalosis). In two cases, the renal findings of primary hyperoxaluria were diagnosed by ultrasound and computed tomography scans. In addition to renal involvement, both patients had liver involvement, and one patient had cardiac involvement.
