Aim: The study's aim was to determine the utility of 68-Gallium DOTATATE positron emission tomography (PET)-CT scanning in patients with carcinoid-like symptoms and negative anatomical imaging.
Methods: Retrospective analysis of 22 of 196 patients with carcinoid-like symptoms and no evidence of primary neuroendocrine tumor (NET) based on anatomical imaging and endoscopy who underwent 68-Gallium DOTATATE PET-CT as part of a prospective clinical trial.
Results: Of the biochemically positive patients (n = 11), 18% (n = 2) had additional evidence of NETs based on 68-Gallium DOTATATE PET-CT. Of the patients identified by 68-Gallium DOTATATE PET-CT, 50% (n = 1) had a treatment change and 100% showed symptom improvement. Of the biochemically negative patients (n = 11), 68-Gallium DOTATATE PET-CT identified NETs in 64% (n = 7). Change in management occurred in 71% patients, and 57% of patients showed symptom improvement.
Conclusion: 68-Gallium DOTATATE PET-CT imaging is useful in detecting NETs in symptomatic patients with negative anatomical imaging and changes the treatments in these patients.

First reported case of multiple endocrine neoplasia type 1 in an Australian Aboriginal.
Endocrinol Diabetes Metab Case Rep
July 2024
Alice Springs Hospital, Alice Springs, Northern Territory, Australia.
Article Synopsis
- - The case study discusses a 48-year-old Aboriginal Australian woman diagnosed with Multiple Endocrine Neoplasia type 1 (MEN1), who faced significant health issues including hypercalcaemia, following a history of parathyroid surgery and several severe medical conditions, indicating the complexity of her case.
- - Genetic testing revealed a rare variant in the MEN1 gene, but cultural and logistical challenges hindered effective genetic counseling for her family, highlighting gaps in healthcare support for remote Aboriginal communities.
- - The case underscores the critical need for improved genetic counseling approaches and timely recognition of rare diseases in remote areas, as late diagnoses can lead to severe health consequences, as seen in her unfortunate passing in 2021.
Clinical characteristics and surgical outcomes of vertebral lesions associated with tumor-induced osteomalacia: report of 16 patients and review of the literature.

Department of Endocrinology, Key Laboratory of Endocrinology, National Commission of Health, Peking Union Medical College Hospital, Chinese Academy of Medical Science, No. 1 Shuaifuyuan, Wangfujing Street, Dongcheng District, Beijing, 100730, China.
Article Synopsis
- - Low detection rates and poor outcomes for vertebral tumors in tumor-induced osteomalacia (TIO) patients highlight the need for improved diagnostic methods, with Ga-DOTATATE-PET/CT showing a 100% sensitivity in detecting these tumors compared to traditional methods.
- - The study focuses on 16 adult TIO patients who underwent surgery for vertebral lesions, comparing the results of two surgical approaches: tumor curettage and segmental resection.
- - Segmental resection is recommended over tumor curettage as it results in higher recovery rates for patients with vertebral TIO, emphasizing the importance of selecting the right surgical method.
A Rare Cyclic Cushing Syndrome Mystery Illustrates Diagnostic Principles.

Pheochromocytomas predominantly produce catecholamines, and rarely also produce ACTH, causing Cushing syndrome (CS). Cyclic CS, an uncommon presentation of hypercortisolism, poses a diagnostic challenge. We report a 71-year-old woman who developed cyclic ectopic ACTH secretion from a pheochromocytoma.

Primary mesenteric neuroendocrine tumors represent a rare clinical entity, challenging to manage, while a combination of imaging is demanded in order to differentiate it from metastatic disease, and set the diagnosis. If the tumor is resectable, surgery is the fundament of the therapeutic approach. The appearance of a second primary mesenteric tumor suggests an unacquainted scenario.

The authors present the case of a 59-year-old lady diagnosed with lymphoepithelial carcinoma (LEC) of the left parotid gland. The primary tumour was identified using contrast-enhanced CT, and diagnosis was confirmed via fine needle aspiration cytology and immunohistochemistry. Staging using fluorine-18 fluorodeoxyglucose PET CT revealed regional nodal metastases, while no distant metastasis was evident.
