#4651 Neuroendocrine hyperplasia of infancy (NEHI) vs. diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH): What is the difference?

Introduction: Neuroendocrine Hyperplasia of Infancy (NEHI) is a rare disease that belongs to the group of interstitial lung disease in children; characterised by hypoxemia, tachypnoea, and respiratory distress, often misdiagnosed as reactive airway disease or bronchiolitis. The diagnosis relies on histologic evaluation. We describe the clinical presentation and paraclinical characteristics of paediatric patients with NEHI.

#4631 Correlations between dosimetry and imaging in patients with neuroendocrine tumour treated with 177Lu-DOTATATE

Introduction: Tumour dose may be an important predictor of clinical response, but estimation of a clinically relevant tumour-absorbed dose without high risk of toxicity is challenging.

#4507 Biliary complications for metastatic patients with neuroendocrine tumours of the pancreatic head and their influence on survival: Is it necessary to change the current management?

Introduction: Neuroendocrine tumours of the pancreatic head (NETPH) can be associated with local complications. At the metastatic stage, surgery of the primary tumour (PT) is not a standard of care. But the biliary complications (BC) due to the untreated NETPH may complicate the management and deteriorate the prognosis.

#4247 Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia - A case report

Introduction: Idiopathic Diffuse Neuroendocrine Diffuse Neuroendocrine Hyperplasia is a rare, but increasingly recognized entity that primarily affects middle-aged and elderly women, Of available therapies, somatostatin analogs and mTOR are the most promising

#3842 Long response to 177-Lu DOTATATE of a long malignant metastatic pheochromocytoma survivor

Introduction: A 64-year-old man was admitted on November 2010 with a CT-scan showing a 9cm right adrenal mass and high 24-hour urine metanephrins and cathecolamins. The mass was resected in December 2010 confirming a pT3N1 pheochromocytoma (PHEO). In May 2013 he presented a local recurrence that was resected proving metastatic lymphatic tissue. On May 2014 biochemical progression preceded a CT scan showing retroperitoneal lymphadenophaties with MIBG uptake. He was then treated with 131I-MIBG (two cycles) until May 2015, having biochemical and radiological response. After lymphatic tumor progression in January 2018, he received two more cycles of 131I-MIBG therapy (cumulative dose 800mCi) with proven refractory disease. He continued follow-up until two new abdominal masses appeared in October 2020. A high uptake in the 99Tc octreotide scintigraphy showed somatostatin receptors expression. The patient refused to participate in a clinical trial, so he was treated off-label with 177Lu-DOTATATE (800mCi) four doses from February to July 2021 achieving a near-complete response.
