Background: Osteoid osteoma is a benign tumor, predominantly affects the younger age group with characteristic nocturnal symptoms, relieved by rest and anti-inflammatory drugs. It can affect any bone; most common site is shaft of long bones of lower limb (90%). It is quite uncommon to find osteoid osteoma in acromion of scapula.
Background: Radioiodine therapy has long been used in the treatment of hyperthyroid patients. Salivary complications secondary to radioactive iodine (RAI) treatment are well documented, there is little in the literature addressing salivary gland duct obstruction. We present a rare case of salivary gland duct obstruction developed 2 months after RAI treatment.
Case Presentation: We describe a 50-year-old male, treated with RAI for hyperthyroidism. He developed pain and swelling in the left submandibular region, 2 months after receiving RAI treatment (25 mCi). His salivary gland scintigraphy was done after injecting 370 MBq (15 mCi) of Tc99m pertechnetate in supine position. It revealed retention of radiotracer in the left submandibular gland with no drainage through the duct system, even on giving lemon stimulus, favoring submandibular gland duct obstruction.
Conclusion: We report this rare complication of submandibular gland duct injury occurring after RAI therapy. The occurrence of this complication even after low dose of radioiodine administration may be listed in gamut. All necessary measures must be taken to reduce such potential complications.
Background: Gallbladder agenesis is an extremely rare, usually asymptomatic anatomic variation. Enterogastric reflux (EGR) in a patient with gallbladder agenesis was not reported previously. We report a rare case of EGR in a patient with gallbladder agenesis, diagnosed on 99mTc HIDA (hepatobilliary iminodiacetic acid) SPECT-CT (single-photon emission computed tomography-computed tomography) scintigraphy.
Case Presentation: A 35-year-old female was referred to Nuclear Medicine Department for Tc99m HIDA scan. She had history of surgical exploration to remove the gallbladder due to suspicion of chronic cholecystitis. But intraoperatively gallbladder was not localized and the patient was referred for Tc99m HIDA scan. Tc99m HIDA scan along with SPECT-CT showed reflux of tracer into the stomach and non-visualized gallbladder. Further imaging by magnetic resonance cholangiopancreatography confirmed the diagnosis of congenital absence of the gallbladder.
Conclusion: We conclude that 99mTc HIDA SPECT-CT scintigraphy is helpful in evaluating the true etiology of biliary colic. It should be cautiously reported, mentioning the EGR if present as it may be the true etiology of biliary colic in patients with and without gall bladder. It prevents the added morbidity of surgery, performed with the suspicion of cholecystitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
