Case ReportsBilateral fatigue fractures of the radial shaft in a gymnast.
A 24-year-old female gymnast had a 3-month history of bilateral forearm pain. A Tc-99m MDP bone scan demonstrated focally increased activity in the radial shafts on blood pool and delayed images, characteristic of fatigue fractures. ⋯ Upper extremity fatigue fractures, in contrast, are uncommon and usually involve the humerus or ulna. Fatigue fracture of the radial shaft from gymnastic exercise has not been previously reported.

Case ReportsScintigraphic findings of osteomyelitis after intraosseous infusion in a child.
A case of unilateral tibial osteomyelitis in a 20-month-old child after bilateral intraosseous infusion (IOI) needle placement is presented. A review of the indications, potential complications, and scan findings is discussed. This case also shows the lack of significant uptake in the noninfected side, suggesting that a three-phase bone scan is of value in differentiating reactive bone from infected bone in patients with IOI.

Case ReportsIntrathoracic splenosis mimicking metastatic lung cancer.
A case of posttraumatic intrathoracic splenosis mimicking lung cancer is presented. The diagnosis was made by a radiocolloid liver-spleen study followed by a heat-damaged Tc-99m labeled red cell scan. A favorable change in the staging of the patient's real contralateral lung cancer resulted.

Case ReportsMediastinal uptake of I-131 in a hiatal hernia mimicking recurrence of papillary thyroid carcinoma.
I-131 is used to image patients diagnosed with papillary or follicular carcinoma of the thyroid after thyroidectomy to observe for metastatic disease or residual thyroid tissue. I-131 is excreted in gastric mucosa and is seen in the esophagus after the swallowing of saliva. The authors describe a patient in whom radiopharmaceutical activity in the mediastinum was subsequently shown to be due to a hiatal hernia.

Case ReportsHiatal hernia on whole-body radioiodine survey mimicking metastatic thyroid cancer.
Total body I-131 scanning done on a 67-year-old woman with thyroid cancer revealed abnormal tracer uptake within the mid-thorax, thought to represent metastasis in the mediastinum or thoracic spine. Single-photon emission computed tomography images of the thorax showed contiguity between the thoracic uptake and the normal, physiologic uptake of radioiodine in the stomach, suggesting physiologic accumulation within a hiatal hernia. ⋯ A hiatal hernia was also observed as an incidental finding on chest radiographs and an MRI. This case illustrates the potential for an abnormal anatomic configuration to mimic metastatic thyroid cancer and shows how SPECT and oral Tc-99m SC images may be useful in making this distinction.
