Detection of melorheostosis in a young lady with upper limb pain on Three Phase Bone Scintigram/SPECT-CT.

Melorheostosis is a benign, noninheritable bone dysplasia characterized by its classic radiographic features of dense, flowing hyperostosis. It frequently affects one limb, usually the lower extremity and rarely the axial skeleton. A 26-year-old lady with obesity, polycystic ovarian syndrome and scalp dandruff presented with a long standing history of upper extremity pain and inability to adduct the arm completely.

Coil embolization of posttraumatic pseudoaneurysm of the ophthalmic artery causing subarachnoid hemorrhage. Case report.

The authors report a unique case of subarachnoid hemorrhage caused by a traumatic pseudoaneurysm of the ophthalmic artery, which was successfully treated with coil embolization. Clinical and imaging features, as well as the relevant literature, are described.

Temporary balloon occlusion to test adequacy of collateral flow to the retina and tolerance for endovascular aneurysmal coiling.

Two carotid ophthalmic artery aneurysms with incorporation of the artery into the neck were referred for endovascular assessment. Temporary balloon occlusion at the aneurysm neck was performed in an attempt to assess the adequacy of collateral flow to the retina. During inflation, the patients reported visual deterioration that resolved upon deflation, which indicates that collateral blood flow was insufficient.

Gadolinium leakage into the surgical bed mimicking residual enhancement following spinal cord surgery. Case report.

Intramedullary spinal cord surgery can disrupt the blood-spinal cord barrier and cause intravascular contents to leak into the surgical cavity. Immediate postoperative Gd-enhanced magnetic resonance (MR) imaging can demonstrate leakage of contrast into the surgical bed and complicate the assessment of whether a residual enhancing tumor is present. The authors report a case in which the preoperative lesion was nonenhancing and not expected to enhance on postoperative imaging.
