Localized primary breast amyloidosis is a very rare benign disease characterized by abnormal protein deposition in the mammary glands. Amyloidosis may mimic the appearance of a number of pathologies, both benign and malignant. Clinically, the patient may present with a breast mass or simply with increased breast density and skin thickening. Herein, we report the case of a 45-year-old woman who presented with a breast mass and was ultimately diagnosed with primary breast amyloidosis, and the mass diagnosed with amyloidosis increased in size and there were a greater number of amorphous and irregular microcalcifications on mammography and ultrasound at the 1-year follow-up. To conclude, we presented changes in a case of localized primary breast amyloidosis on mammography and ultrasound images over a period of 1 year. The current standard of care of primary breast amyloidosis is surgical resection; however, the patient should be followed after surgery to monitor the possibility of recurrence of malignancy.

Spinal subdural hematoma is a rare condition presenting with symptoms of back pain and neurologic deficits. The etiology is largely idiopathic, followed by anti–coagulant use and vascular malformation. Traumatic subdural hematomas associated with compression fractures are rare, with only a few old case reports. Magnetic resonance imaging is the modality of choice for the diagnosis of spinal subdural hematoma. Treatment is surgical decompression when neurologic deficits exist; however, conservative management is a good option in patients without neurologic symptoms with reported spontaneous hematoma regression. Herein, we report 3 cases of spinal subdural hematoma, 2 spontaneous cases related to anti–platelet agent use and 1 with acute traumatic compression fracture. T1-weighted fat-saturated images clearly showed the hematoma and increased the confidence level of the diagnosis. In summary, we suggest that magnetic resonance imaging can clearly visualize the spinal subdural hematoma and is excellent for diagnosis and follow up. Anti–platelet agent use and compression fracture are probable etiologies of spinal subdural hematoma.
