Osteofibrous dysplasia or ossifying fibroma is an uncommon benign fibro-osseous lesion of childhood, commonly described in the maxilla and the mandible. Among long bones, it usually presents in the tibia as a painless swelling or anterior bowing. Ossifying fibroma of clavicle has never been reported in English literature, to the best of our knowledge. Here, we would like to present an unusual case of osteofibrous dysplasia of clavicle clinically mimicking chronic osteomyelitis.

Primary tumors of spine are rare accounting for less than 5% of new bone tumors diagnosed every year. These tumors may exhibit characteristic imaging features that can help in early diagnosis and improved prognosis. Plasmacytoma/multiple myeloma and lymphoproliferative tumors are the most common malignant primary spinal tumors. Hemangioma is the most common benign tumor of the spine. Computed tomography is useful to assess tumor matrix and osseous change. Magnetic resonance is useful to study associated soft tissue extension, marrow infiltration, and intraspinal extension...

Hip replacement surgery helps millions of people worldwide walk painlessly each year. With increasing life spans and decreased clinical threshold for surgery, this number will continue to rise. With the increase in the number of surgeries and the longevity of implants, the need for early and prompt diagnosis of complications is also rising. This essay underlines the fact that magnetic resonance imaging on a 1.5T scanner with specialized metal artefact reduction sequences is a viable technique to image the post-arthroplasty hip and has vast potential in the prompt and early diagnosis of complications in these patients...

We report a rare case a 15 year old boy who presented with recurrent hemoptysis. There was past history of pancreatitis. A CT scan of thorax revealed a small collection in the region of the tail of the pancreas and a tract from it extending across the diaphragm into the posterobasal segment of left lower lobe, suggesting a pancreatico-pleuro-pulmonary fistula. The fistula was embolised by percutaneous injection of glue into the collection and fistula, which resulted in good symptom control.

Central venous catheterization through internal jugular vein is done routinely in intensive care units. It is generally safe, more so when the procedure is performed under ultrasound guidance. However, there could be inadvertent puncture of other vessels in the neck when the procedure is not performed under real-time sonographic guidance. Closure of this vessel opening can pose a challenge if it is an artery, in a location difficult to compress, and is further complicated by deranged coagulation profile. Here, we discuss the removal of an inadvertently placed catheter from subclavian artery with closure of arteriotomy percutaneously using arterial suture-mediated closure device...

The Amplatzer Vascular Plug (AVP) is a cylindrical plug made of self-expanding nitinol wire mesh with precise delivery control, which can be used for a variety of vascular pathologies. An AVP is an ideal vascular occlusion device particularly in high-flow vessels, where there is high risk of migration and systemic embolization with traditional occlusion devices. We performed 28 embolizations using the AVP from 2009 to 2014 and achieved complete occlusion without complications.

PURPOSE: The OUTBACK(®) catheter is a reentry device that enables reentry into a vessel lumen from the subintimal space during subintimal angioplasty. It is reserved for cases where reentry has not been possible using conventional wire and catheter techniques. We report a two-center experience in recanalization of the chronic total occlusions of the common iliac (CIA) and the superficial femoral artery (SFA) using the OUTBACK(®) catheter in cases where other techniques were unsuccessful...

Ectopic thyroid is a rare developmental anomaly with lingual thyroid accounting for majority of the cases. The presence of ectopic thyroid tissue lateral to the midline is very rare, and very few cases located in the submandibular region have been reported. The simultaneous finding of submandibular ectopic thyroid tissue and a functional orthotopic thyroid gland is even rarer. In the differential diagnosis of an ectopic submandibular thyroid, it is fundamental to exclude a metastasis from well-differentiated thyroid cancer, even when primary thyroid carcinoma is not demonstrable...

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...

The number of women undergoing breast implant procedures is increasing exponentially. It is, therefore, imperative for a radiologist to be familiar with the normal and abnormal imaging appearances of common breast implants. Diagnostic imaging studies such as mammography, ultrasonography, and magnetic resonance imaging are used to evaluate implant integrity, detect abnormalities of the implant and its surrounding capsule, and detect breast conditions unrelated to implants. Magnetic resonance imaging of silicone breast implants, with its high sensitivity and specificity for detecting implant rupture, is the most reliable modality to asses implant integrity...

We report a rare case of esophageal lung in a neonate who presented with repeated chest infections and respiratory distress. Chest radiograph revealed increased opacification of the right lung with reduced lung volume and air bronchograms. Further evaluation with computed tomography (CT) showed the presence of only left mainstem bronchus at the tracheal bifurcation. Right mainstem bronchus originated from distal esophagus and aerated the right lung. Nasogastric tube was inserted into the stomach with injection of small amount of dilute barium through it, which established the communication of right mainstem bronchus with esophagus...

Dual left anterior descending artery is a rare coronary artery anomaly showing two left anterior descending arteries. Short anterior descending artery usually arises from the left coronary artery, while long anterior descending artery has anomalous origin and course. Dual left anterior descending artery with origin of long anterior descending artery from the pulmonary artery (ALCAPA) is a very rare coronary artery anomaly which has not been reported previously in the literature. We present the computed tomography coronary angiographic findings of this rare case in a young female patient who presented with atypical chest pain...

The present case report is computed tomography (CT) coronary angiographic depiction of an exceedingly rare entity-single right coronary artery arising from the right sinus of Valsalva with the absence of equivalent left coronary artery system branches and associated mitral valve prolapse. Even though a statistical rarity, it is potentially fatal and can cause myocardial ischemia, sudden cardiac death, and warrants immediate clinical attention. Further, the report reveals the decisive role of CT coronary angiogram in the diagnosis of such rare entities, in contrast to catheter angiography, which may be inconclusive...

Chronic thromboembolic pulmonary hypertension is a morbid condition associated with complications such as hemoptysis, right heart failure, paradoxical embolism, and even death. There is no known association of chronic thromboembolic pulmonary hypertension with pulmonary arteriovenous malformation. Possible hypothesis for this association is an increased pulmonary vascular resistance leading to the compensatory formation of pulmonary arteriovenous malformation. We present one such case presenting with hemoptysis that was managed with endovascular treatment...

Sternal variations and anomalies have been identified in the past during autopsy or cadaveric studies. Recently, an increasing number of minor sternal variations have been reported with the advent of multidetector computed tomography (CT). Although there are many sternal variations that occur with varying appearance and prevalence, most of them are not recognized or are underreported during routine imaging of thorax. Identification of sternal variations is important to differentiate from pathological conditions and to prevent fatal complications prior to sternal interventions like marrow aspiration or acupuncture...

Crohn's disease (CD) is a chronic inflammatory bowel disease that often requires frequent imaging of patients in order to detect active disease and other complications related to disease activity. While endoscopy is the gold standard for diagnosis, it may be contraindicated in some patients and has a limited role in detecting deep submucosal/mesenteric diseases and intra abdominal complications. In recent years, magnetic resonance enterography (MRE) has evolved as a noninvasive, radiation free imaging modality in the evaluation of patients with CD...
