Osteomyelitis from a retained foreign body should be included in the differential diagnosis of any osteolytic lesion of the foot. We report here a case of a 59-year-old man who presented with swelling over the dorsolateral aspect of the right foot. Plain x-ray showed an osteolytic lesion that mimicked a pseudotumor. Magnetic resonance imaging (MRI) showed multilocular fluid collection over the right cuboid with a hypointense lesion over the plantar fascia. The patient underwent surgery and a rubber fragment (1 cm × 0.8 cm) was removed from his foot that had been present for two years following a stabbing injury. The patient fully recovered without complication or disability.

Paraspinal Abscess

Here presented is a case involving a 44-year-old man with a chief complaint of sharp lateral right-sided rib pain with notable radiation to the anterior portion of the thorax and minor radiation around the lateral back. The etiology of the pain and radiculopathy, which was initially attributed to a right-sided rib fracture, was later accurately credited to a paraspinal abscess discovered on a lateral X-ray of the thoracic spine. Subsequently, studies including Magnetic Resonance Imaging (MRI), Computed Tomography (CT), and bone scan all confirmed the diagnosis of a paraspinal abscess between the right lobe and its neighboring T9 and T10 vertebrae. The mass was biopsied and methicillin sensitive Staphylococcus aureus was isolated. Appropriate surgical and medical intervention was possible due to the early diagnosis of the abscess.

Objective Intraocular foreign body (IOFB), a frequent cause of ocular trauma, causes serious damage to the eyes. This study was designed to elaborate and compare the characteristics of different magnetic resonance imaging (MRI) sequences in detecting wooden IOFBs in rabbits. Methods The right vitreous of 24 healthy rabbits was randomly implanted with diverse wooden foreign bodies (diameter φ = 0.2 mm). The T1-weighted imaging (T1WI), T2-weighted imaging (T2WI), proton density-weighted imaging (PDWI), and susceptibility-weighted imaging (SWI) sequences were applied individually 2 weeks after the implantation. Results IOFBs were detected as linear low signals on T1WI, T2WI, PDWI, and SWI (SWI image). The detectable rates of poplar wood with a length of 0.5 mm were 0%, 50%, 0%, and 67% for T1WI, T2WI, PDWI, and SWI, respectively. SWI and T2WI sequences exhibited higher sensitivity than T1WI and PDWI. The detectable rates of the first three SWI sequences (magnitude, phase, and SWI) were all 67%, which was higher than that of the minimum intensity projection sequence (33%). Conclusion MRI is practicable in the diagnosis of wooden IOFBs. SWI and T2WI are optimal for the integrated diagnosis of wooden IOFBs and could be used for diagnosis and immediate treatment.

Calcific tendinitis of the shoulder joint, also known as chemical furuncle of the shoulder, causes intense shoulder pain and usually occurs within 1–2 cm from the insertion of the rotator cuff. We experienced a rare case of calcific tendinitis in the posterosuperior labrum of the shoulder joint in a 39-year-old male patient who presented with severe pain and weakness in the right shoulder. Radiographs and magnetic resonance imaging (MRI) findings showed calcific tendinitis in the posterosuperior labrum of the shoulder joint. A 1-week attempt at conservative treatment failed, so the calcified deposit in the posterosuperior labrum was arthroscopically removed. The patient’s symptoms were completely relieved, and satisfactory clinical outcomes were achieved. Postoperative follow-up X-ray and MRI showed no recurrence of calcific tendinitis.

To identify and localize an intraorbital wooden foreign body is often a challenging radiological issue; delayed diagnosis can lead to serious adverse complications. Preliminary radiographic interpretations are often integrated with computed tomography and magnetic resonance, which play a crucial role in reaching the correct definitive diagnosis. We report on a 40 years old male complaining of pain in the right orbit referred to our hospital for evaluation of eyeball pain and double vision with an unclear clinical history. Computed tomography and magnetic resonance scans supposed the presence of an abscess caused by a foreign intraorbital body, confirmed by surgical findings.

Abstract A 54-year-old man with a right hemiparesis was found to have an intrasellar intercarotid communicating artery associated with agenesis of the right internal carotid artery. Magnetic resonance imaging (MRI) studies demonstrated the spatial relationship of the anomalous artery to the surrounding structures, thus suggesting an embryonic enlargement of the capsular artery as a source of this anomalous artery.

History Of Depression

A 27-year-old woman presented to the emergency room after having witnessed generalized tonic clonic seizure while asleep. Birth and development were normal. She had suffered a single febrile seizure at 13 months of age, but had no other seizure risk factors. She was otherwise well except for a history of depression for which she was taking sertraline. Depressive symptoms had been well controlled over the past 3 months, but she had been under increased stress working to finish a doctoral thesis. Neurological examination was normal. Magnetic resonance imaging (MRI) showed modest asymmetry of the hippocampi, slightly smaller on the right, but no abnormal signal and well-preserved laminar anatomy. An electroencephalogram was negative. She was discharged from the emergency room with no treatment. Three weeks later, the patient's boyfriend witnessed an episode of behavioral arrest with lip smacking and swallowing automatisms lasting 45 seconds, after which the patient was confused for 20–30 minutes. The next morning she and her boyfriend kept a previously scheduled appointment with a neurologist.

Acoustic Emission Analysis

The knee joint, being the largest joint in the human body, is responsible for a great percentage of leg movements. The diagnosis of the state of knee joints is usually based on X-ray scan, ultrasound imaging, computerized tomography (CT), magnetic resonance imaging (MRI), or arthroscopy. In this study, we aimed to create an inexpensive, portable device for recording the sound produced by the knee joint, and a dedicated application for its analysis. During the study, we examined fourteen volunteers of different ages, including those who had a knee injury. The device effectively enables the recording of the sounds produced by the knee joint, and the spectral analysis used in the application proved its reliability in evaluating the knee joint condition.

Enteric duplication cysts are rare congenital anomalies that are prenatally diagnosed through antenatal ultrasonography (US). In female patients, however, attention must be paid since these formations might be confused with ovarian cysts. Herein, we present a case of a low birth weight female infant with an enteric duplication cyst. A cystic lesion was detected in the right abdomen of the fetus on antenatal US and magnetic resonance imaging (MRI). Serial US and MRI examinations performed after birth showed a single cyst that wandered from side to side in the abdomen; the initial diagnosis was thought to be an ovarian cyst. During laparotomy, however, it was found to be an enteric duplication cyst with volvulus. To our knowledge, there has been no report of an enteric duplication cyst presenting as a wandering abdominal mass. Our experience indicates that early intervention is necessary for patients who have a wandering abdominal mass to avoid complications and urgent surgery, whether it is an ovarian cyst or an enteric duplication cyst.

Progressive Dysphagia

A 52-year-old woman was referred for a progressive neurological condition which started a year before with continuous irregular twitching of the right facial and arm muscles as well as the tongue and palate, followed by progressive dysphagia, right hemiparesis, ataxia, dysphasia and dysarthria. Though magnetic resonance imaging (MRI) at clinical presentation and a year after were both normal (Figure A1), Rasmussen's encephalitis (RE) was strongly suspected and treatment with corticosteroids and immunoglobulins were begun. A third MRI, two years after onset, revealed mild T2 hyperintense subcortical white matter changes over the left perisylvian region (Figure A) which confirmed our initial suspicion of RE as she now met clinical, electrophysiological and morphological criterias for RE. While waiting for a cerebral biopsy after unsatisfactory response from antiepileptic drugs, corticosteroids and immunoglobulins, her condition markedly worsened less than three years after onset with the sudden occurrence of status epilepticus requiring intubation and continuous infusions of midazolam and propofol.

In vivo dynamic changes in the interosseous membrane (IOM) during forearm rotation were studied using magnetic resonance imaging (MRI). The right forearms of 20 healthy volunteers were examined in five different rotational positions. Axial slices were obtained at the proximal quarter, the middle and the distal quarter of the forearm. The changes in shape of the IOM during rotation were observed in an axial MR plane. For each image, we measured the interosseous distance and the length of the interosseous membrane. Images of the tendinous and membranous parts of the IOM could be differentiated by thickness. There were minimal dynamic changes in the tendinous part on the MRI while the membranous part showed numerous changes during rotation. The interosseous distance and the length of the interosseous membrane were maximum from a neutral to a slightly supinated position. The tendinous part is considered to be taut during rotation to provide stability between the radius and the ulna, but the membranous part which is soft, thin and elastic, allows smooth rotation.
