Sinus of Valsalva aneurysm dissecting and forming sinus tract into interventricular septum is an extremely rare complication of sinus of Valsalva aneurysm. Echocardiography and conventional angiography were used earlier to diagnose ruptured sinus of Valsalva aneurysm. Cardiac CT has emerged as a valuable non-invasive diagnostic tool for evaluation of complications of sinus of Valsalva aneurysm. In this article, we report two cases of ruptured sinus of Valsalva aneurysm arising from right and left coronary sinuses into the interventricular septum without aorto-cardiac shunt formation evaluated using 256 slice cardiac CT imaging. After diagnosis on cardiac CT, these findings were confirmed perioperatively and were repaired surgically.

A cholesteatoma is a non-neoplastic lesion of the petrous temporal bone commonly described as “skin in the wrong place.” It typically arises within the middle ear cavity, may drain externally via tympanic membrane (mural type), or may originate in the external auditory canal (EAC). The latter type is rarely encountered and typically affects the elderly. EAC cholesteatoma poses diagnostic challenges because it has numerous differential diagnoses. The present case describes a 19-year-old male who presented with gradually progressive diminution of hearing in a previously naïve right ear since 8 months. A soft tissue attenuation lesion confined to the right EAC with erosion of the canal on computed tomography prompted magnetic resonance imaging (MRI). The lesion showed restricted diffusion on MRI. Thus, a diagnosis of spontaneous EAC cholesteatoma was established. The case elucidates the rarity of spontaneous EAC cholesteatoma in a young male. In addition, it describes the role of imaging to detect, delineate the extent, and characterize lesions of petrous temporal bone. The case also discusses common differential diagnoses of EAC cholesteatoma, as well as the importance of diffusion weighted imaging in EAC cholesteatoma similar to its middle ear counterpart.

Osseous metaplasia of the endometrium is a rare condition characterized by the presence of mature or immature bone in the endometrium. Most cases present with secondary infertility following an abortion or chronic endometritis. Some patients are asymptomatic, while others have menstrual abnormalities such as menorrhagia or oligomenorrhea. Removal of the bony fragments helps in spontaneous conception. We hereby present two cases of osseous metaplasia of the endometrium with radiological and pathological correlation.
