Article Abstract
Aim: The aim of this study was to evaluate a new imaging method 68Ga-DOTATATE PET/CT as an alternative method to diagnose evidence of neuroendocrine tumors or their metastasis (if any) in patient with MEN 2A.
Methods: Three patients( 2F, 1M; age 28,46 and 50 years) with MEN 2A syndrome who underwent 68Ga-DOTATATE PET/CT scan were prospectively evaluated. PET/CT images were analyzed with measurement of maximum standardized uptake value (SUVmax).
Results: All patients had adrenal masses with increased uptake of 68Ga-DOTATATE (first case adrenal mass SUVmax: 9,1, second case adrenal mass SUVmax: 32,4(right), 30,3(left) and third case SUVmax:12,4). All of the patients had medullary thyroid carcinoma with increased uptake of 68Ga-DOTATATE (first case SUVmax: 3,3 second case SUVmax:7,7 and third case SUVmax: left thyroid nodule: 19,4, right thyroid nodule: 21,2). Third case has a parathyroid adenoma with SUVmax: 2,8.
Conclusions: New imaging method 68Ga-DOTATATE PET/CT may be an alternative method to diagnose MEN 2A patients. 68Ga-DOTATATE PET/CT can give a great opportunity to detecting the multiple neoplasia like MEN 2A with only one session.
Key Words: MEN 2A syndrome, 68Ga-DOTATATE PET/CT, Neuroendocrine tumors.

Port site metastasis is an uncommon but clinically relevant complication, particularly associated with minimally invasive surgery for abdomino-pelvic malignancies, often indicating poor prognosis and necessitating prompt evaluation for potential surgical intervention. Proposed mechanisms include direct tumor implantation, aerosolization during pneumoperitoneum, surgical wound contamination, and immune alterations. In this report, we describe a case of a 48-year-old man who developed SSTR-expressing port site metastases, occurring 4 years and 4 months following laparoscopic resection of an ileal neuroendocrine tumor (NET).

This case report presents a diagnostically challenging pulmonary typical carcinoid tumor with localized pleural involvement, initially misdiagnosed intraoperatively as small cell carcinoma. Despite the presence of pleural nodules, typically staged as M1a disease, histopathology confirmed a low-grade neuroendocrine tumor with favorable features, including a low Ki-67 index and absence of necrosis. Somatostatin receptor imaging using 68Ga-DOTATATE positron emission tomography/computed tomography (PET/CT) revealed no distant spread.

Purpose: This study aimed to elucidate the molecular and genetic factors contributing to negative Ga-DOTATATE PET imaging in neuroendocrine tumors (NETs). By integrating whole exome sequencing (WES) and single-cell RNA sequencing (scRNA-seq), we sought to unravel the interplay between negative results of Ga-DOTATATE PET and genetic mutations in NETs.
Methods: A total of 18 patients with lung, ileal, or pancreatic NETs who underwent Ga-DOTATATE and F-FDG PET/CT scans as part of their initial diagnostic workup were retrospectively reviewed.

A 6-year-old boy with refractory high-risk neuroblastoma underwent 68 Ga-DOTATATE PET/CT to evaluate the therapy response. The initial scan revealed multiple metastatic lesions, including bone, lymph nodes, and lung involvement. After 2 cycles of combination therapy, follow-up 68 Ga-DOTATATE PET/CT demonstrated an increase in both the number and extent of lesions compared with the baseline scan, indicating disease progression.

A 56-year-old male patient underwent total thyroidectomy, and pathology revealed multicentric papillary thyroid cancer. His post-operative stimulated thyroglobulin value was >500 ng/mL. F-fluorodeoxyglucose positron emission tomography (PET) computed tomography revealed hypermetabolic metastatic pulmonary nodules, cervical, and mediastinal lymph nodes.
