Posterior reversible encephalopathy syndrome in a adult female

Posterior reversible encephalopathy syndrome is a clinico-neuroradiologic diagnosis, with rapidly evolving neurologic condition, characterized by headache, confusion, altered mental status, seizures, cortical blindness, lethargy, stupor, and occasionally, focal neurological signs accompanied by a typical computed tomography or magnetic resonance imaging pattern. With early recognition and treatment, complete resolution of symptoms occurs. Typical imaging findings characteristically involve the white matter bilaterally in the parieto-occipital regions. Atypical imaging finding of contrast enhancement of lesion can occur, but is less common. A 20-year-old primiparous lady presented with posterior reversible encephalopathy syndrome. To the best of our knowledge, this is the first documented case in Nigeria. This case-report highlights the importance of recognizing the salient imaging features in this lethal but reversible entity with prompt management.

Traumatic diaphragmatic hernia masquerading as left- sided hydropneumothorax: a case report

Abstract Traumatic diaphragmatic rupture (TDR) is rare in children and can be easily overlooked because of lack of awareness of late presentation and concomitant injuries. A 4-year-old girl presented with respiratory distress 2 months after a road traffic accident. The initial differential diagnosis was pneumonia or pulmonary tuberculosis with associated pleural effusion. On further assessment, a diaphragmatic hernia was suspected. The initial radiograph showed left hydropneumothorax. Fluoroscopy, follow-up chest radiographs and barium swallow confirmed the diagnosis of left TDR. Surgery was undertaken but unfortunately she did not survive. Awareness of delayed presentation of TDR is essential for prompt management.

Neuroimaging of young adults with stroke in Ilorin Nigeria

BACKGROUND Stroke in young adults is relatively uncommon. Computed tomography (CT) and magnetic resonance imaging (MRI) are the most valuable tools for the diagnosis of stroke. Recent data on stroke in young adults in Nigeria is sparse. The aim of this study is to document the imaging pattern in young patients aged 15-45 years with suspected cerebrovascular accidents (CVA) in the Nigerian environment. MATERIALS AND METHODS This was a retrospective study of 69 patients aged 15-45 years, with clinical diagnosis of stroke, referred for neuro-imaging, from October 2008 to November 2013. All patients with the clinical diagnosis of stroke within this age group were recruited into the study. Images were obtained from a four slice channel general electric CT machine and a 0.2 Tesla Siemens Magnetom Concerto MRI scanner. RESULTS A total of 69 patients (44 males and 25 females) were studied. Sixty out of 69 (87.0%) patients were accurately diagnosed with CVA, with 9 (13.0) cases of misdiagnoses. A total of 21 (35%) out of the 60 cases confirmed on imaging had intracerebral hemorrhage (ICH), 10 (16.7%) had subarachnoid hemorrhage (SAH) and 29 (48.3%) had cerebral infarct (CI). Hypertension was the common risk factor for all stroke subtypes. The most common location for ICH, was the basal ganglia in 8 (38.8%), while the commonest pattern for CI, was lacunar infarct in the basal ganglia (51.7%). CONCLUSION The incidence of hemorrhagic CVA (ICH and SAH combined) was slightly higher than ischemic CVA in this study. Lacunar infarcts in the basal ganglia and also ICH in the basal ganglia were the most common patterns, both are strongly linked to hypertension. A diagnostic protocol of stroke in young adults, to include neuroimaging and other ancillary investigations is advocated for stroke in young adults as some of the etiologies are treatable.

Congenital giant hydroureteric cistern in a duplex system of an infant.

Duplex collecting system is a congenital genitourinary anomaly commonly found incidentally. Our experience with a duplex system associated with giant hydroureter presenting as mobile abdominal swelling that was noticed from birth, constipation, and failure to thrive is described. Ultrasound and IVU did not assist in making the diagnosis, while a barium enema suggested a colonic duplication. Congenital giant hydroureter should be considered as a differential diagnosis in infants with cystic abdominal swelling. A preserved renal moiety attributed to a dilated ureteric cistern was a unique theory in this case.

Fulminant tuberculosis: Simultaneous shoulder and pulmonary involvement

Fulminating tuberculosis (TB) of the shoulder joint and lung occurring concurrently is rare. A case diagnosed by plain radiograph in a 60-year-old peasant who had left shoulder swelling, pain and limitation of movement of this joint for six months is presented. This is for radiologist and clinicians to be wary of TB in cases of non-resolving osteoarticular infection especially in TB endemic regions. Despite growing advances in radiological methods, plain radiograph should remain a valuable investigation. The patient had satisfactory response to 12-month anti-tuberculous regimen.
