Article Abstract

An 81-year-old woman was evaluated for a stroke. CT showed no intracranial abnormalities but diffuse patchy aspect of the neurocranium. An MRI and F-NA PET/CT were performed to differentiate between metastases, Paget disease, hyperostosis frontalis interna, and primary malignancy. MRI yielded no additional findings. F-NA PET/CT showed diffusely increased uptake in the skull and 4 spots with intense uptake. No other suspicious skeletal foci were seen elsewhere. Low-dose CT showed no sign of malignancy elsewhere. Image findings together with elevated serum alkaline phosphatase levels, slightly increased calcium levels, and normal phosphorus levels were interpreted as pathognomic for monostotic Paget.

In a 2015 study of mutation carriers who had initial negative bone scintigraphy, we found that the rate of development of Paget's disease of bone (PDB) over 5 yr was low. We report here an additional 8-yr follow-up of this cohort, exploring the hypothesis that the rate of development of PDB would increase as the cohort aged. In the current study, 21 of 24 subjects from 2015 who had a negative bone scintiscan at baseline and at first follow-up, had a repeat scintiscan and measurement of total serum alkaline phosphatase activity.

Purpose: The aims of the current study were to describe clinical and biochemical features of patients with Paget disease of bone (PDB) followed at our medical center, and to examine the long-term effectiveness of zoledronate.

Methods: Retrospective cohort study included consecutive patients≥18 years with a diagnosis of PDB, followed in the Rabin Medical Center (RMC) Institute of Endocrinology from 1973 to 2023. The cohort comprised two groups: patients treated/not treated with zoledronic acid (ZOL/NZOL).

Background: Paget Disease (PD) is usually asymptomatic and discovered incidentally, it is known that it is exhibited low to high grade increased F-18 FDG uptake.

Aim: In this study, we investigated the distinguishability of FDG PET/CT in incidental PD cases from other bone diseases and at different stages of the disease.

Patients And Methods: In this cross-sectional, descriptive study, "Paget" identification associated with PET/CT reports was found in 69 of 18,119 studies (~3.

Background/objective: Denosumab is a monoclonal antibody that inhibits bone resorption and is indicated for the treatment of osteoporosis, bone metastases, and giant cell tumor of bone. We describe a woman with symptomatic Paget disease of the skull whose headaches and monostotic disease of the skull improved after receiving denosumab for concomitant low bone density.

Case Report: A 75-year-old woman presented with unremitting headache of 1 month.

Introduction: Patients with Paget's disease develop abnormal bony anatomy which can result in significantly altered lower limb alignment predisposing them to early secondary osteoarthritis. Due to the severe extra-articular deformity, total knee arthroplasty (TKA) in these patients is challenging. Conventional knee arthroplasty using intramedullary guides is not an option and can lead to erroneous limb alignment postoperatively.
