We present the case of a 56-year-old gentleman who presented with non specific malaise, myalgia and anorexia. Clinical examination revealed a large circumscribed palpable mass in the left iliac fossa. He underwent an intraabdominal pelvic biopsy, computed tomography (CT), magnetic resonance imaging (MRI) of abdominal wall and Positron Emmission Tomography (PET). Differential diagnoses included Gastro Intestinal Stromal Tumour (GIST) and sarcoma. He underwent a laparotomy and excision of the lesion. Histological analysis of the lesion demonstrated a dedifferentiated liposarcoma involving the colon and adjacent pericolic fat. Margins were clear and there was no nodal involvement. He declined adjuvant chemotherapy. He subsequently developed a local recurrence, which was deemed unresectable. He commenced chemotherapy but continued to deteriorate. He received palliative treatment and died 6 months following his initial surgery.

The palpable mass over the groin region include inguinal or femoral hernia, enlarged lymph nodes, aneurysm or pseudoaneurysm, synovial cyst and iliopsoas ganglion. Among these diagnoses, patients with femoral hernia are at risk of bowel obstruction or strangulation; so it should be treated as an emergency. Ultrasound and magnetic resonance imaging (MRI) are helpful for differential diagnosis. We report a case with a large iliopsoas ganglion located around the distal iliopsoas muscle and tendon with pseudopodia extending close to the joint capsule, mimicking femoral hernia clinically. The patient underwent excision and no recurrence was noted at one-year follow-up.

Management of invasive aspergillosis of the paranasal sinuses requires sufficient experience to initiate appropriate investigations and then utilize the correct treatment protocol. Computed tomography (CT) or magnetic resonance imaging (MRI) is essential to show the extent of the disease and diagnosis is confirmed by histological analysis. Aspergillus flavus is a ubiquitous soil saprophyte in the Sudan and is responsible for many cases originating from this area. The literature is reviewed and treatment options discussed.

Background: Risk factors for intracerebral hemorrhage (ICH) include hypertension and cerebral amyloid angiopathy (CAA). The objective of this study was to determine the autopsy prevalence of CAA and the potential overlap with other risk factors among patients who died from ICH and also the correlation of CAA with cerebral microbleeds. Methods: We analyzed 81 consecutive autopsy brains from patients with ICH. Staining for CAA detection was performed. We used an age- and sex-matched control group of routine brain autopsies of nonneurological patients to determine the frequencies of CAA and hypertension. Postmortem 3D T2-weighted gradient-echo magnetic resonance imaging (MRI) with a 1.5-T magnet was performed in 11 brains with ICH (5 with CAA and 6 without) and histological correlation was performed when microbleeds were detected. Results: Hypertension and CAA were found in 69.1 and 24.7% of cases respectively. Among patients with CAA, 65.0% also had hypertension. The prevalence of CAA was similar among non-hypertensive cases and controls (33.3 and 23.1%; p = 0.54), whereas a significant difference was found between hypertensive cases vs. controls (28.9% vs. 0; p = 0.01). MRI documented 48 microbleeds and all 5 brains with CAA had ≥1 microbleed, compared to 3/6 brains without CAA. Among 48 microbleeds on MRI, 45 corresponded histologically to microbleeds surrounding microvessels (23 <200 µm in diameter, 19 between 200 µm and 2 mm, 3 were hemosiderin granules). Conclusions: Both hypertension and CAA frequently coexist in patients with ICH. MRI-detected microbleeds, proven by histological analysis, were twice as common in patients with CAA as in those with hypertensive ICH.

To clarify the diagnostic capabilities of magnetic resonance imaging (MRI), it was compared with clinical and X-ray examinations. Were used such traditional methods as cranio, angiography, tomography. A total of 40 patients with brain pathology (tumors, vascular malformations, multiple sclerosis, etc.) were observed. The diagnosis was verified by the results of surgery and histological analysis.

AbstractWhen it comes to examining the brachial plexus, ultrasound (US) and magnetic resonance imaging (MRI) are complementary investigations. US is well placed for screening most extraforaminal pathologies, whereas MRI is more sensitive and accurate for specific clinical indications. For example, MRI is probably the preferred technique for assessment of trauma because it enables a thorough evaluation of both the intraspinal and extraspinal elements, although US can depict extraforaminal neural injury with a high level of accuracy. Conversely, US is probably the preferred technique for examination of neurologic amyotrophy because a more extensive involvement beyond the brachial plexus is the norm, although MRI is more sensitive than US for evaluating muscle denervation associated with this entity. With this synergy in mind, this review highlights the tips for examining the brachial plexus with US and MRI.
