We report a 26-year-old male patient who was admitted to our emergency department after a traffic accident and who suffered from neck pain. We have found accidentally a dorsal spinous process schisis, a very rare vertebral abnormality, that we recognized in the X-rays imaging performed for the study of the lung parenchyma.

Cerebral venous air embolism is a relatively rare condition that arises from iatrogenic or traumatic introduction of air into the venous system. We describe the ultrasonographic findings in a 1-day-old infant with iatrogenic retrograde cerebral venous air embolism, which to our knowledge, is the earliest case reported in the literature to date. This case highlights the role of cerebral ultrasonography in the detection and surveillance of cerebral venous air embolism in neonates.

Zhen Kang, Xiangde Min, Liang Wang
Local fat infiltration of the thoracic cavity is a rare initial presentation of Bochdalek hernia. We report a case of Bochdalek hernia in a child with leukemia that demonstrated initial local fat infiltration of the thoracic cavity on computed tomography scan and progressed to an obvious diaphragmatic hernia on subsequent follow-up. We suggest that initial local fat infiltration of the thoracic cavity on computed tomography scan may indicate a potential diaphragmatic hernia.

Immunoglobulin G4-related disease (IgG4RD) is an immune-mediated condition characterized by lymphoplasmacytic infiltrates and fibrosis of affected organs. IgG4RD may affect many different organs either individually or together in a multiorgan condition and, thus, incorporates a wide range of fibroinflammatory phenotypes with shared pathologic features. Although IgG4RD most commonly occurs in late adulthood, it may affect children and adolescents. Only one case of IgG4RD presenting as isolated submandibular gland involvement has been reported in the pediatric population...

Postmortem magnetic resonance imaging (MRI) is emerging as a valuable tool to accompany traditional autopsy and has potential for use in cases when traditional autopsy is not possible. This case report will review the use of postmortem MRI with limited tissue sampling to differentiate between metastatic neuroblastoma and hepatoblastoma which could not be clearly differentiated with prenatal ultrasound, prenatal MRI, or emergent postnatal ultrasound. The mother presented to our institution at 27 weeks gestation after an obstetric ultrasound at her obstetrician's office identified a large abdominal mass...

Burkitt lymphoma (BL) is the most frequent non-Hodgkin lymphoma in pediatric patients, accounting for approximately 34% of the cases of lymphoma in children. This subtype of non-Hodgkin lymphoma was first described in 1958 as a monoclonal proliferation of B cell lymphocytes. Cardiac involvement of BL in association with osseous compromise and lymphadenopathy is rare and poorly documented. We report a case of femur primary BL in an 8-year-old boy with metastatic cardiac involvement, retroperitoneal and iliofemoral lymphadenopathy, and hepatosplenomegaly...

A 58-year-old man was diagnosed with advanced hepatocellular carcinoma with portal vein tumor thrombosis (PVTT). The tumors were multiple and existed in both lobes. Drug-eluting beads transcatheter arterial chemoembolization (DEB-TACE) was performed for the tumors in the left lobe. Embosphere and Hepasphere were selected for embolization of the arterioportal shunt, followed by loaded epirubicin infusion into the left hepatic artery. Computed tomography showed reduction of PVTT. However, liver failure progressed, and the patient died 67 days after DEB-TACE...

Calciphylaxis is a rare devastating medical condition commonly associated with end-stage renal disease and characterized by extensive microvascular calcifications. We describe a case of calciphylaxis presenting on Tc-99m MDP bone scan imaging with asymmetric radiotracer uptake within the lower extremities corresponding to extensive soft tissue calcifications on Computed tomography. Familiarity with the classic clinical presentation and imaging features of this rare entity may help its early identification and treatment...

We describe the bone scan and single-photon emission computed tomography/computed tomography findings in calcific tendinitis of the gluteus maximus and discuss its pathophysiology. Although this tendinopathy is mostly self-limiting, awareness of this disease is important for 2 reasons. First, it may explain acute hip symptoms in patients in the resorptive phase of the calcifications. Second, it should be considered as a differential diagnosis for bone scan hot spots in the vicinity of the gluteus maximus tendon and for cortical erosion seen in that region on X-rays or CT...

I-131 uptake in the breast has been described with a variety of normal and pathologic conditions. We present the case of a 38-year-old female who received 317 millicuries of radioactive I-131 treatment for papillary thyroid carcinoma. Post-treatment scan demonstrated I-131 uptake in an area of fat necrosis in the breast.

A 78-year-old male presented to the Emergency Department complaining of a 1-week onset of increasing fatigue and anorexia. The patient was previously well but had a history of depression, chronic diarrhea, and hypertension. His examination was remarkable for mild fever (100.1°F). He had no acute neurologic deficits. The patient felt better after intravenous fluids and was discharged to follow-up with the primary care provider. With no resolution of symptoms and new memory loss, the patient's primary care doctor ordered an MRI which revealed abnormal signal/patchy enhancement of the left temporal lobe indicative (pathognomonic) of herpes simplex encephalitis...

Primary intracranial choriocarcinoma (PICCC), a type of germ-cell tumor, is a very rare primary tumor of the central nervous system that generally arises in the pineal or suprasellar region. We present a case of a teenage boy with PICCC of the bilateral basal ganglia, an anatomic site for which we were unable to find the previous reports. We offer discussion of the differential diagnosis, imaging characteristics, and prognosis of PICCC and germ-cell tumors of the basal ganglia, in the hope that it will increase awareness and allow for early detection...

Isolated traumatic oculomotor nerve palsy without internal ophthalmoplegia is a rare condition after closed head trauma. The nerve strain leads to intraneural edema with nerve swelling on T2-weighted magnetic resonance (MR) images and traumatic disruption of the blood peripheral nerve barrier with contrast enhancement on T1-weighted MR images. In this patient, susceptibility-weighted MR imaging allowed the direct visualization of the intraneural hemorrhage after suspected traumatic diffuse neuronal axonal injury...

Yunsuk Her, Jin Pyeong Jeon, Hyuk Jai Choi, Yong Jun Cho
Endovascular treatment of deeply located bilobulated aneurysms in elderly patients is still challenging because of the acute angulation of the carotid siphon and poor microcatheter support. In particular, generating a frame coil to cover each lobe is difficult in bilobulated aneurysms with narrow isthmus in the fused portion. Here, we report a successfully treated bilobulated aneurysm using a modified coil protection technique with stent assistance.

We report a rare case of disseminated coccidioidomycosis with multifocal musculoskeletal involvement. The patient presented to the emergency department with left shoulder pain and swelling. Magnetic resonance imaging of the left shoulder revealed enhancing soft tissue masses, bony lesions, and fluid collections in and around the glenohumeral joint with involvement of the proximal humerus, glenoid, and rotator cuff musculature. Multiple additional areas of involvement were subsequently discovered. Fungal cultures confirmed coccidioidomycosis infection at all surgical sites with superimposed polymicrobial bacterial infection in the left shoulder...

Tarsal coalition is a condition described by partial union between tarsal bones. Its clinical significance is the potential cause for chronic pain in the ankle and foot. Diagnosis of this condition may be delayed until adolescence or early adulthood, and is often made incidentally on examination for other purposes. Treatments for this condition can range from conservative options to surgical approach. The calcaneonavicular and talocalcaneal subtypes make up the majority of this condition, with involvement among other tarsal bones much rarer in comparison...

We report 2 cases of obturator internus muscle strains. The injuries occurred in young male athletes involved in kicking sports. Case 1 details an acute obturator internus muscle strain with associated adductor longus strain. Case 2 details an overuse injury of the bilateral obturator internus muscles. In each case, magnetic resonance imaging played a crucial role in accurate diagnosis.

A case of a right knee intra-articular osteolipoma in a 64-year-old man is reported. The patient presented for evaluation of a 1-year history of nontraumatic, mechanically-exacerbated, medial-sided right knee pain. Radiographs demonstrated a partially calcified 3.0 cm mass anterior to the distal medial femur at the suprapatellar fossa. Magnetic resonance imaging examination confirmed a 4.0 × 3.6 cm well-circumscribed mass deep to the medial patellofemoral ligament, with predominantly fat characteristics on T1-weighted and T2-weighted sequences...

Joelle R Harwin, Michael L Richardson
We report a typical case of "tennis leg", in which the main finding was a fluid collection between the medial head of the gastrocnemius and soleus muscles. Since the first clinical description of this entity in 1883, the injury has been attributed to rupture of the plantaris tendon. However, recent studies of this condition with sonography and magnetic resonance imaging have shown that most of these cases are actually due to injury to the gastrocnemius and/or soleus muscles, and up to 10% are due to deep venous thrombosis masquerading as muscle injury...
