An Incidental Detection of Breast Cancer Osteolytic Bone Metastasis Using a 99m Tc-TRODAT-1 SPECT Scan.

This report presents a case of suspected Parkinson disease in a 76-year-old woman with a history of slurred speech, general weakness, unstable gait, and bradykinesia for months. A 99m Tc-TRODAT-1 SPECT scan revealed a symmetrically decreased bilateral nigrostriatal system, including bilateral putamen and caudate nuclei. The scintigraphic findings may reflect normal aging or atypical parkinsonism.

Rare finding of primary aortoduodenal fistula on single-photon emission computed tomography/computed tomography of gastrointestinal bleeding: A case report.

Background: Primary aortoduodenal fistula is a rare cause of gastrointestinal (GI) bleeding consisting of abnormal channels between the aorta and GI tract without previous vascular intervention that results in massive intraluminal hemorrhage.

Case Summary: A 67-year-old man was hospitalized for coffee ground vomiting, tarry stools, and colic abdominal pain. He was repeatedly admitted for active GI bleeding and hypovolemic shock.

Zollinger-Ellison syndrome: Revelation of the gastrinoma triangle.

Zollinger-Ellison syndrome is a complex condition in which one or more tumors form in the patient's pancreas or upper duodenum. These tumors, called gastrinomas, secrete excessive amounts of gastrin, and almost all develop ulcers. The vast majority of gastrinomas are present within the "gastrinoma triangle," which is composed of the porta hepatis, duodenal sweep, and pancreatic head.

Bisphosphonate-related osteonecrosis of the jaw complicated by Ludwig's angina.

Ludwig's angina is a life-threatening cellulitis that involves the submandibular and sublingual spaces. It often occurs after an infection of the roots of the teeth. However, modern dental care and use of antibiotics for oral infections have made Ludwig's angina rare.

Unusual site of metastasis detected with FDG PET/CT in a case of recurrent rectosigmoid cancer.

Metastatic colon cancers to the oral cavity are unusual, involving a majority of the mandible rather than the oral soft tissues. We describe a rare site of gingival metastasis in a case of rectosigmoid cancer. The patient was a 74-year-old woman who developed swelling and persistent bleeding of the right mandibular gingiva after tooth extraction.

Hallucal sesamoiditis manifested on bone scan.

The first metatarsal articulation bears one third of the weight of the forefoot. The hallucal sesamoids are embedded in the flexor hallucis brevis and connected by the intersesamoid ligament and plantar plate. The sesamoid apparatus acts as a pulley to help pull the big toe down against the ground during walking.

Gorham's disease: the disappearing bone.

Gorham's disease is a rare disorder characterized by proliferation of vascular channels. The clinical presentation of Gorham's disease is variable and depends on the site of involvement. A high index of clinical suspicion is needed for accurate diagnosis, and recognition of distinctive radiologic and histopathologic features can help facilitate and expedite diagnosis.

Compartment syndrome following robotic-assisted prostatectomy: rhabdomyolysis in bone scintigraphy.

Major urologic surgery performed in the lithotomy position sometimes results in the serious complication of rhabdomyolysis. A 56-year-old man was admitted to the hospital for prostate adenocarcinoma. A whole-body bone scan was performed to exclude bony metastases, which demonstrated no bone lesions but showed intense soft-tissue activity in gluteus maximus muscles, findings suggestive of a myopathy.

Supernumerary breast masquerading as metastasis on serial 67Ga scan.

We report the incidental discovery of supernumerary breast changes on sequential ⁶⁷Ga scans in a woman with dermatofibrosarcoma protuberans excised 5 years before. The appearance of the accessory breast fluctuated with physiological ⁶⁷Ga uptake of the breast tissue was evident. Awareness of the concomitant changes in accessory breast with breast tissue could help narrow the differential diagnosis.
