Multiphasic CT and MR Imaging Findings of an Isolated Transverse Colon Hemangioma

Colonic hemangiomas are rare benign mesenchymal tumors but can potentially cause a life-threatening bleeding. Although phlebolith on simple radiography or CT scan is a pathognomonic sign of colonic hemangioma, it may not be always present. With wider use of cross-sectional images, it is necessary to know the imaging findings of the colonic hemangiomas on multiphasic scan and MRI for the correct diagnosis and management of the disease.

Appendiceal intussusception

Appendiceal intussusception (AI) is an unusual and rarely reported clinical entity. It was first described by McKidd in a 7-year-old boy in 1858. Since then the literature on it has been confined to a few case reports and very small cases series, in totally about 300 cases being published. Because of variations of clinical symptoms and lack of pathognomonic sign, rarety of the pathology and diversity of causing factors, accurately detection of the presence or absence of appendiceal pathology is difficult. However, imagistic and endoscopic methods may be useful in AI detection and play a large and important role in differential diagnosis. Treatment of AI differs significantly depending on underlying pathological condition, benign or malignant.

Differential Laboratory Diagnosis of Acute Fever in Guinea: Preparedness for the Threat of Hemorrhagic Fevers

Acute febrile illnesses occur frequently in Guinea. Acute fever itself is not a unique, hallmark indication (pathognomonic sign) of any one illness or disease. In the infectious disease context, fever’s underlying cause can be a wide range of viral or bacterial pathogens, including the Ebola virus. In this study, molecular and serological methods were used to analyze samples from patients hospitalized with acute febrile illness in various regions of Guinea. This analysis was undertaken with the goal of accomplishing differential diagnosis (determination of causative pathogen) in such cases. As a result, a number of pathogens, both viral and bacterial, were identified in Guinea as causative agents behind acute febrile illness. In approximately 60% of the studied samples, however, a definitive determination could not be made.

Pediatric Abusive Head Trauma: A Systematic Review

Abusive head trauma (AHT) represents a commonly misdiagnosed condition. In fact, there is no pathognomonic sign that allows the diagnosis in children. Therefore, it is such an important medico-legal challenge to evaluate reliable diagnostic tools. The aim of this review is to evaluate the current scientific evidence to assess what the best practice is in order to diagnose AHT. We have focused particularly on evaluating the importance of circumstantial evidence, clinical history, the use of postmortem radiological examinations (such as CT and MRI), and the performance of the autopsy. After autopsy, histological examination of the eye and brain play an important role, with attention paid to correlation with symptoms found in vivo.

Primary Intramedullary Hydatid cyst

Hydatid cysts or Hydatid disease is caused by Echinococcus granulosus infestation. Dogs, wolves, and other carnivores are the definitive host, and human being the accidental intermediate hosts. This disease commonly involves the liver and lungs and rarely involves other organs of the body. Primary intramedullary hydatid cysts are extremely rare and few cases before us have been reported in the literature. There is no pathognomonic sign or symptom for spinal hydatid cyst, mostly compression related symptoms, e.g. radiculopathy, myelopathy, local pain, and pathologic fractures are found. So preoperative diagnosis of spinal hydatid requires the correlation of all the aspects including clinical features, radiology, and lab reports. Surgical management is the best treatment for spinal hydatid cyst with complete excision without cyst rupture being the primary target along with complete neural elements decompression. Here we report a case of a 26-year old male with paraparesis with MRI finding directing towards D9-D10 intramedullary cystic lesion (cystic astrocytoma) which was completely excised and histopathology report favored intramedullary hydatid cyst.

Presentation of a Rare Case: Acute Kidney Failure Developed Following Complete Urinary Bladder Herniation and Management of Postoperative Voiding Dysfunction

Inguinal bladder herniation is seen in 1% -4% of all inguinal hernia cases; most of them are asymptomatic and come up with swelling in the groin. In symptomatic cases, nonspecific findings such as lower urinary tract symptoms or pain due to strangulation of the hernia sac are seen. Two-stage micturition (manual pressure to the scrotum to empty residual urine) is a pathognomonic sign for the advanced case. Vesicoureteral reflux (VUR), bilateral hydronephrosis, urinary tract infection, acute kidney failure and bladder wall necrosis are complications that may be seen if the problem is not appropriately managed. Preoperative diagnosis rates are low (<7%) and 16% of the cases are diagnosed in the postoperative period, and most cases are detected intraoperatively. Radiologic examination performed for other indications such as non-contrast abdominal computed tomography (CT) may diagnose the bladder herniation. CT, cystography and ultrasonography are the techniques that can be used in the diagnosis and differential diagnosis. Intraoperatively, reduction of the herniated bladder with herniorrhaphy is a routine procedure. Partial cystectomy has to be made in case of bladder wall necrosis, presence of a tumor in the herniated bladder and narrow bladder neck which don"t allow reduction. In this case report, our aim is to explain the management of left inguinoscrotal complete bladder herniation and postoperative voiding problem.

Karhart’s notch in ear diseases

According to the literature and our research, Karhart’s notch, as a local increase in bone conduction thresholds at frequencies of 500-3000 Hz, is observed not only in otosclerosis, but also in other diseases of the middle ear, especially – with adhesive and secretory otitis. Therefore, it is not appropriate to use the presence of a Karhart’s notch as a pathognomonic sign of otosclerosis. Audiometric diagnostics of non-purulent ear diseases should definitely be supplemented with impedance audiometry.
