We present a case of pulmonary embolism that occurred during the injection of lipiodol during transcatheter arterial chemoembolization under general anaesthesia. A 7-year-old child suffering from a large hepatoblastoma was admitted for arterial chemoembolization and carcinostatic administration. Pulmonary embolism due to lipiodol during arterial chemoembolization was evident by a sudden fall in oxyhaemoglobin saturation from 100 to 90%. This was associated with a spread of lipiodol into both lungs, particularly the middle lung zones and detected by chest fluoroscopy. Arterial blood gases returned to normal values 1 day later but pulmonary infiltration persisted for 7 days before final clearance. Pulmonary embolism caused by lipiodol during arterial chemoembolization is infrequent, but such a complication could prove fatal. Understanding the risk of pulmonary embolism in patients receiving lipiodol, during and after arterial chemoembolization, and late onset pulmonary injury is important and a close follow-up for several days after arterial chemoembolization is advisable.

Wilms tumor is the most frequent pediatric renal malignancy, and its usual presentation is an abdominal mass or hematuria. Unusual presentations have also been reported, such as paraneoplastic syndromes (acquired von Willebrand disease, sudden death due to pulmonary embolism, and Cushing syndrome). These conditions can precede, occur concomitantly, or present in a later phase of tumor development. Precocious puberty, as paraneoplastic endocrine syndrome, has already been described in children with malignant tumors (brain, gonadal, adrenal tumors, and hepatoblastoma). However, little is known about central precocious puberty, as paraneoplastic manifestation of nephroblastoma or secondary to its specific chemotherapy. Here, we report a case of Wilms tumor and simultaneous precocious puberty in a 5-year-old girl. The initial diagnosis was premature telarche, but the clinical and biological pubertal progression changed our diagnosis to idiopathic central precocious puberty. Chemotherapy and nephrectomy were well tolerated, and we began treatment with a gonadotropin-releasing hormone agonist which showed favorable outcomes over the short term. We highlight the need for early diagnosis and work-up in all patients of precocious puberty, in order to institute timely management.

Although hepatoblastoma is rare, it is the most malignant tumour of childhood. Treatment is usually done by surgical resection and chemotherapy. The mortality and morbidity have decreased due to improvements in the treatments. In this process, hepatic resection has a risk of pulmonary embolism, and this condition could be fatal. In this case, a 9-month-old patient who was treated with chemotherapy and then underwent hepatectomy was presented. We used non-invasive methods such as the perfusion index (PI), the plethysmographic variability index (PVI) (Massimo Radical 7) and non-invasive total haemoglobin measurement (SpHb) rather than invasive measurements. During closure of the surgical skin incision, the end-tidal CO2 (ETCO2) value dropped, after which arrhythmia and bradycardia resulted in cardiac arrest. Cardiopulmonary resuscitation (CPR) was initiated. However, the patient did not respond to CPR. We concluded that heparin may be administered to reduce the risk of thrombosis in patients undergoing liver surgery.
