Acute hydrops of the gallbladder is described in one patient who had mucocutaneous lymph node syndrome. During the course of her illness, acute addominal pain, vomiting and right upper guadrant tenderness were developed. Diagnosis was readily made with ultrasonography, and the patient was followed with this te-chnique. We managed her conventionally without surgical intervention. The galbladder returned to normal size within about 3 weeks. Related literatures are briefly reviewed.

Intravascular ultrasound (IVUS) imaging was performed to assess the coronary wall morphology in detail at 22 months after the onset of Kawasaki disease in a girl who had developed coronary aneurysms at 4 yr of age. The sites of persistent aneurysms demonstrated a dilated lumen with a marked symmetrical or asymmetrical thickening of the intima-media complex. This pathologic finding was also present in angiographically normal vessels near an aneurysm but with a mild thickening. Coronary artery calcification was observed at one site in the aneurysms. The sites of normal coronary artery far from an aneurysm showed normal intravascular ultrasound findings with no measurable intima-media complex. Our case indicates that the healing process may continue via cell proliferation, with extension to the proximity of the coronary aneurysms. IVUS is useful to evaluate the coronary wall morphology and may be valuable in the long-term follow-up of coronary lesions due to Kawasaki disease.

A female patient with mucocutaneous lymph node syndrome is presented. During the course of her illness, she developed acute abdominal pain secondary to hydrops of gallbladder. The diagnosis was facilltated by ultrasound. We managed her conventionally without surgical intervention. It is interesting that the age of patients complicated by gallbladder hydrops is high compared with the age frequency of MCLS. Related literatures are briefly reviewed.

We evaluated clinical factors such as age, gender, predisposing diseases and ultrasonographic findings that determine clinical outcome of acute acalculous inflammatory gallbladder diseases in children. The patients were divided into the four age groups. From March 2004 through February 2014, clinical data from 131 children diagnosed as acute acalculous inflammatory gallbladder disease by ultrasonography were retrospectively reviewed. Systemic infectious diseases were the most common etiology of acute inflammatory gallbladder disease in children and were identified in 50 patients (38.2%). Kawasaki disease was the most common predisposing disease (28 patients, 21.4%). The incidence was highest in infancy and lowest in adolescence. The age groups were associated with different predisposing diseases; noninfectious systemic disease was the most common etiology in infancy and early childhood, whereas systemic infectious disease was the most common in middle childhood and adolescence (P = 0.001). Gallbladder wall thickening was more commonly found in malignancy (100%) and systemic infection (94.0%) (P = 0.002), whereas gallbladder distension was more frequent in noninfectious systemic diseases (60%) (P = 0.000). Ascites seen on ultrasonography was associated with a worse clinical course compared with no ascites (77.9% vs. 37.7%, P = 0.030), and the duration of hospitalization was longer in patients with ascites (11.6 ± 10.7 vs. 8.0 ± 6.6 days, P = 0.020). In conclusion, consideration of age and predisposing disease in addition to ultrasonographic gallbladder findings in children suspected of acute acalculous inflammatory gallbladder disease might result in better outcomes.

Kawasaki disease (KD) is a systemic vasculitis that occurs predominantly in infants and young children. The etiology of KD is unknown and coronary heart disease is a major complication of KD. Acute scrotum is a rare complication of acute KD, and not as well recognized as other manifestations of the disease. We report a 2-month-old boy with acute scrotum in the acute phase of KD. He was treated with intravenous immunoglobulin (total 2 g/kg) and aspirin (50 mg/kg/day). The treatment was effective in resolving his fever and other clinical symptoms, but 2 days after starting treatment he experienced scrotal swelling. Scrotal ultrasound and transillumination were used in the diagnosis of acute scrotum. After 2 months, a follow-up testicular ultrasound revealed a remission of the acute scrotum. Subsequently, he has been followed up for KD.

Retinoblastoma, the most common primary intraocular malignancy of childhood, usually presents in the first three years of life. Atypical presentation of retinoblastoma can masquerade as virtually any ocular or orbital pathology, which may lead to diagnostic dilemmas especially in the presence of other systemic diseases. We report a 20-month-old boy who was diagnosed with coronary aneurysm as a complication of Kawasaki disease, and presented with sudden left eye redness. His mother noticed the presence of white pupillary reflex three months earlier. Atypical acute ocular presentation secondary to Kawasaki disease was initially suspected, but the presence of multiple calcification and mild proptosis on imaging suggested characteristics of advanced retinoblastoma. Histopathological examination of the enucleated eye, which revealed a classical rosette pattern appearance, confirmed the diagnosis. Atypical presentations of retinoblastoma are usually associated with advanced disease. The presence of other systemic conditions further complicates the diagnosis. Early diagnosis is important to reduce the mortality and morbidity.

We report a 38-year-old man with previous Kawasaki disease who presented with exertional dyspnoea and was found to have multivessel coronary aneurysm and stenoses on coronary angiography. Coronary artery bypass surgery was subsequently performed. This case highlights the angiographic and intravascular ultrasonographic imaging features of this relatively uncommon condition presenting to an adult general cardiology service in Singapore.

The incidence of coronary artery disease requiring coronary intervention in patients with Kawasaki disease is high. Because coronary artery lesions in Kawasaki disease commonly involve severe calcification and aneurysmal changes which can progress with time, in contrast with adult atherosclerotic coronary artery lesions, the indication or technique of catheter intervention for adult patients cannot be directly applied. However, the experience of coronary intervention in Kawasaki disease is extremely limited compared to that with intervention in adults, which provides satisfactory therapeutic results. There are several kinds of percutaneous coronary intervention techniques in Kawasaki disease including balloon angioplasty, stent implantation, rotational ablation, and directional coronary atherectomy. Satisfactory acute results for coronary balloon angioplasty can be obtained in patients in a relatively short interval from the onset of disease, especially within 6 years. However, the incidence of restenosis after angioplasty is still high. Stent implantation acquires larger luminal area, less restenosis rate and less aneurysmal formation than balloon angioplasty. Rotational ablation is a good interventional option with high success rate for longstanding Kawasaki disease with severe calcification. Intravascular ultrasound imaging provides valuable information for the selection of the appropriate interventional procedure and the assessment of postprocedural outcomes. To obtain good result and optimal decision making, cooperation between pediatric and adult cardiologists is essential. Postprocedural anticoagulation or antiplatelet regimens are required for proper long-term management.
