Introduction: Anorectal melanoma (ARM) is rare and highly lethal neoplasm. It has a poorer prognosis compared with cutaneous ones. Sentinel lymph node biopsy (SLNB) has become the preferred method of nodal staging method for cutaneous melanoma.

The aim of this study was to evaluate the potential effects of boron-doped nano hydroxyapatite grafts on craniofacial bone regeneration in critical bone defects in the mandibular corpus of rats, in terms of scintigraphic and histopathological aspects. Forty Wistar albino rats, with an average weight of 200-220 g, aged 16-18 weeks, and all male, were used in the study. The rats were randomly assigned to five groups, each containing 8 rats, as follows: group C1 (no procedure applied to the mandible), group C2 (surgical defect created in the mandible but no treatment applied), group nHA (nano hydroxyapatite applied to the surgical defect area), group nHA + B1 (nano hydroxyapatite + 1% boron applied to the surgical defect area), and group nHA + B2 (nano hydroxyapatite + 2% boron applied to the surgical defect area).

Thoracoabdominal duplication cysts are a congenital malformation of the posterior primitive foregut with synchronous thoracic and abdominal duplication cysts being found in up to 15% of cases. The presentation of duplication cysts depends on their location, size, and other factors, like the presence of ectopic functioning gastric mucosa, which is reported in 20%-30% of duplication cysts. 99mTc-pertechnetate scintigraphy along with SPECT/CT helps in the preoperative localization of ectopic functioning gastric mucosa in these duplication cysts.

Background: Bone scintigraphy is emerging as a confirmatory diagnostic tool for transthyretin cardiac amyloidosis (ATTR-CA). This study aimed to investigate the frequency and clinical characteristics of patients with incidental cardiac uptake and incidental ATTR-CA on bone scintigraphy.
Methods: All bone scintigraphic studies performed at a tertiary teaching hospital between 2011 and 2022 were reviewed retrospectively.

Article Synopsis
- - Insulinomas are rare but mostly benign tumors found in the pancreas, making their pre-operative localization tricky, with limited data on comparing various imaging techniques for identification.
- - A study involving 37 patients was conducted to examine clinical features and management challenges of insulinomas, revealing that newer imaging techniques like 68Ga Exendin-4 PET-CT showed the highest sensitivity and accuracy in locating the tumors compared to other methods.
- - The study concluded that 68Ga Exendin-4 PET-CT is a highly effective first-line imaging option for insulinomas, with most patients achieving a good prognosis and being cured after surgical removal of the tumors.
