Detection and Intervention of Clinically Masquerading Inferior Mesenteric Artery AVMs
We demonstrate a rare case of inferior mesenteric artery arteriovenous malformations leading to ischemic colitis in a 76-year-old female. Our patient presented with three months of nausea, vomiting, and diarrhea. Colonoscopy displayed diffuse mucosal vascular congestion while CTA and MRA displayed AVMs in the region of the IMA; however, cohesive clinical agreement on AVM from multiple specialties was difficult given its rare occurrence and nonspecific clinical, histopathologic, and directly visualized findings. The three noted dominant AVMs were eventually selected with coil and liquid embolization with successful cessation of symptoms and no major complications. Our discussion focuses on intervention and stressing the importance of radiologic findings, as IMA AVMs, rarely present as ischemic colitis and therefore can clinically masquerade as other etiologies.
Asymptomatic Familial Multiple Cerebral Cavernous Malformation in a 73-Year-Old Woman
Cerebral cavernous malformations (CCMs) are dilated blood vessels which can develop sporadically or in familial form and are the commonest malformations of blood vessels in the spinal cord and brain. The familial form is an autosomal dominant gene mutation disorder. This condition can be diagnosed with magnetic resonance imaging (MRI) and computed tomography (CT) scan, but the modality of choice is MRI because of its high sensitivity. We report a case of a 73-year-old woman with an asymptomatic multiple familial cerebral cavernous malformation (FCCM) which was previously misdiagnosed as multiple cerebral metastases on CT scan. A brain MRI performed correctly diagnosed her condition as FCCM based on the typical MRI appearances. In order not to misdiagnose brain lesions like CCM on CT scan, for cerebral metastases in resource-poor settings, radiologists must recommend advanced imaging modalities like MRI for further evaluation, thereby avoiding unnecessary invasive surgical biopsies.
Eye of the Tiger Sign in Pantothenate Kinase-Associated Neurodegeneration
Pantothenate kinase-associated neurodegeneration (PKAN) is a rare disorder associated with brain iron accumulation caused by a recessive mutation in pantothenate kinase 2 gene (PANK2). We present a case of an 11 year-old boy presenting extrapyramidal signs and developmental regression. T2-weighted images showed the classic eye of the tiger sign seen in pantothenate kinase-associated neurodegeneration.
Renal Cell Carcinoma Metastasis to the Breast: A Rare Presentation
Worldwide breast malignancy is the most common cancer in women; however, metastases to the breast from extramammary malignancies are very rare and only a few sporadic cases are reported in the international literature. In this article, the authors report a case of a 73-year-old woman, who underwent nephrectomy for clear cell renal cell carcinoma and 3 years later presented with a breast metastasis from renal cell carcinoma (clear cell type).
Gastrobronchial Fistula: A Rare Complication of Postlaparascopic Sleeve Gastrectomy—A Case Report and Literature Review
Introduction. Obesity is one of the leading causes of morbidity and mortality in countries all over the world, and its prevalence has been increasing dramatically in recent years. Bariatric surgery is considered the gold standard of care for patients who failed conservative management. Laparoscopic sleeve gastrectomy (LSG) is of increasing popularity. One of its vicious consequences is the development of acquired fistula between the stomach and the tracheobronchial tract due to intractable gastric leak. Case Report. We are presenting a case of a 25-year-old man who underwent laparoscopic sleeve gastrectomy for morbid obesity, which was complicated with the development of gastrobronchial fistula, despite an unremarkable postoperative course. Conclusion. Acquired gastrobronchial fistula due to bariatric surgery is not reported widely in radiologic literature; hence, there is lack of consensus of the diagnostic modality of choice. However, there is a myriad of tests available for diagnosing gastrobronchial fistula, with contrast study of the upper gastrointestinal tract which is the widely accepted diagnostic test.
Amyotrophic Monoplegia Secondary to Posttraumatic Rupture of the Brachial Plexus’s Roots: A Case Report and Review of the Literature
Brachial plexus lesions most often occur in multiple trauma. We report a case of a 37-year-old patient who presented an upper left limb total sensitivomotor deficit and amyotrophy after a cervical and upper limb trauma. Cervical magnetic resonance imaging (MRI) was performed. It noted pseudomeningoceles at the levels of C6-C7, C7-D1, and D1-D2 in T1 hyposignal , T2 and STIR hypersignal , not enhanced by the injection of Gadolinium extending in foraminal and extraforaminal spaces without visualization of the corresponding rootlets. Traumatic brachial plexus injury is a potentially serious debilitating injury which can be well explored on MRI.
