An 80-year-old woman presented to a regional emergency department with postprandial pain, weight loss and diarrhoea for 2 months and a Computed Tomography (CT) report suggestive of descending colon malignancy. Subsequent investigations revealed the patient to have chronic mesenteric ischaemia (CMI) with associated bowel changes. She developed an acute-on-chronic ischaemia that required emergency transfer, damage control surgery and revascularisation. While the patient survived, this case highlights the importance of considering CMI in elderly patients with vague abdominal symptoms and early intervention to avoid potentially catastrophic outcomes.

Radiographic Interpretation

A radiographic interpretation is essential to the diagnosis of invasive cervical resorption (ICR) and the difficulty in distinguishing this lesion from internal root resorption has been highlighted in the literature. This paper reports the use of cone beam computed tomography (CBCT) in the diagnosis of ICR. The cases reports describe how CBCT can be used to make a differential diagnosis and also show that the use of this technology can provide relevant information on the location and nature of root resorption, which conventional radiographs cannot. As a result, the root canal treatment was not initially considered. The patients will be monitored and will undergo a scan after a short period of time to detect any small changes. It was observed that both cases benefited from CBCT in the diagnosis of ICR, because this imaging modality determined the real extent of resorption and possible points of communication with the periodontal space.

Interpretation Of Results

ABSTRACTSubarachnoid hemorrhage (SAH) is an important but uncommon condition in the differential diagnosis of acute headache. Most authorities recommend that patients with suspected SAH undergo noncontrast computed tomography (CT) as a first diagnostic intervention. If the results of the CT scan are negative, a lumbar puncture should be performed. Many nonurban Canadian hospitals do not have CT scanners and must either transfer patients or consider performing lumbar puncture prior to CT. In selected patients, performing lumbar puncture first may be an option, but timing of the procedure and the interpretation of results is important.

Abstract Background Talaromyces marneffei (TM) primarily infects patients with co-morbidities that cause immunodeficiency, but non-secretory myeloma (NSMM) is rare. TSM and NSMM are associated with fever, osteolysis, and swollen lymph nodes, thereby making it difficult for clinicians to make differential diagnosis. In this case, we describe TM infection coexisting with NSMM. Case presentation We retrospectively reviewed the case of a male (without human immunodeficiency virus infection) with fever, thoracalgia, swollen lymph nodes, and subcutaneous nodules who presented to the First Affiliated Hospital of Guangxi Medical University in February 2014. Chest computed tomography revealed patchy infiltration and positron emission tomography/computed tomography showed increased metabolic activity in the lower-right lung, lymph nodes, left ninth rib, and right ilium. Pathological examination of the lung, lymph nodes, subcutaneous nodules, and bone marrow showed no malignancy, he was diagnosed with community-acquired pneumonia. His clinical symptoms did not improve after anti-bacterial, anti-Mycobacterium tuberculosis, and anti-non-M. tuberculosis treatment. Later, etiological culture and pathological examination of the subcutaneous nodule proved TM infection, and the patient was re-diagnosed with disseminated TSM, which involved the lungs, lymph nodes, skin, bone, and subcutaneous tissue. After antifungal treatment, the patient showed significant improvement, except for the pain in his bones. Imaging showed aggravated osteolysis, and bone marrow biopsy and immunohistochemistry indicated NSMM. Thus, we conclusively diagnosed the case as NSMM with TSM (involving the lungs, lymph nodes, skin, and subcutaneous tissue). His condition improved after chemotherapy, and he was symptom-free for 7 years. Conclusion TM infection is rare in individual with NSMM. Since they have clinical manifestation in common, easily causing misdiagnosis and missed diagnosis, multiple pathological examinations and tissue cultures are essential to provide a differential diagnosis.

The adrenal incidentaloma is a lesion of a different etiology and found incidentally in patients who underwent a diagnostic study not about the disease of this organ. Lesions can be both hormonally inactive and hormonally active, can arise from different zones of the adrenal gland or have non-specific organ affiliation, can be benign or malignant. Computed tomography characterization of these lesions, especially the differential diagnosis of benign and malignant, is extremely important for the correct diagnosis in order to provide adequate management of the patient. The article presents the key computed tomography criteria that allow radiologist to characterize the lesion most accurately and consider appropriate diagnosis.
