    Imaging of congenital diaphragmatic hernias
    (2009) Taylor, G. A
    Congenital diapharagmatic hernias are complex and life-threatening lesions that are not just anatomic defect of the diaphragm, but represent a complex set of physiologic derangement of lung, the pulmonary vasculature, and related structures. Imaging plays an increasingly important role in the care of these infants. Prenatal sonograpyh and MRI have allowed early and accurate identification of the defect and associated anomalies. These tools have also been the key to defining the degree of pulmonary hypoplasia and to predicting neonatal survival and need for aggressive respiratory resue strategies. In the postnatal period, conventional radiography supplemented by cross-sectional imaging in selected cases can be very useful in sorting out the diffential diagnosis of intrathoracic masses, in the detection of associated anomalies, and in the management of complications. Understanding the pathogenesis of diaphragmatic defects, the underlying physiologic disturbances, and the strengths and limitations of current imaging protocols is essential to the effective and accurate management of thses complex patients

    Factors influencing the pratcie of hydrostatic reduction of intussusception amongst radiologists in a developing country
    (2009) Lawal, T. A.; Atalabi, O. M.; Adekanmi, A. J.; Ogundoyin, O. O
    Background: Intussesception is a mojor cuase of intestinal obstruction in children and can be treated operatively or non-operatively. Surgery is associated with mortality rates, in dveloping countries of 8.5% to 18%. Hydrostatic reduction is a cost effective treatment that can lower the mortality rate in resource poor settings. However, the teachnique is not widely performed inspite of the advantages. Objectives: We reviewed factors influencing the current practice of hydrostatic reduction of intussusception by radiologists in Nigeria. Materials and Methods: A survey of radiologists was conducted using structured self adminsitered questionnaires. Strenght of assocition between the practice of hydrostatic reduction and variables related to the workforce was evaluated using Fisher's exact test. Result: Fifty-one participants were studied. Three (18.8%) hospitals have at least one consultant radiologist focusing on pediatric surgeon or more. Hydrostatic reduction is practiced in hospitals with a radiologist with interest in pediatric radiology, (p=0.002). Lack of expertise was given as the main reason why hte other hospitals have not commenced the procedure.

    The yield from routine chest X-rays in stage 3 breast cancer patients
    (2008-04) Agunloye, A. M; Elumelu, T.; Adenipekun, A.,; Atalabi, O. M.
    Context: Cancer of the breast is a common malignancy in Nigeria women and various imaging examinations, including the chest radiograph are routinely requested in all patients with this disease. Objective: The objective of the study was to determine the positive yield from routines chest radiographs in Nigeria patients with locally advanced stage 3 breast cancers but who had no clinical symptoms or signs of plumonary or pleural metastatic disease. Methods: This descriptive retrospective study evealuated clinical records and chest radiographs of 61 female Nigerian patients with local stage 3 historically diagnosed breast cancers, who presented at the radiotherapy unit of the University College Hosiptal, Ibadan, over a 12 month period. All abnormalities on the chest radiographs were documented. Results: The ages of the study group ranged from 25 to 67 years with a mean of 47years. Fourty-seven (77%) of the patients had normal chest radiographs. Of the 14 abnormal radiographs, bilateral lung parenchymal metastases were seen in 4 cases one of whom also had bilateral pleural affusion. Other abnormal findings included hilar adenopathy, right lower lobe collapse, lymphagitis carcinomatosis and cardiomegaly. Conclusion: The authors conclude that a 23% detection rate from thses screening chest radiographs is high and should be recommended as over 70% of Nigerian patients with breat cancers present with advanced tumors.

    A lethal form of gorham disease associated with extensive musculoskeletal pneumatosis: cse report and review of the literature
    (2008) Atalabi, O. M; Fishman, S. J.; Kozakewich, H. P.; Alsamarah, A. Y.; Alomari, A. I.
    We report here the imaging finding of a rare case of a lethal form of gorham disease in a yound female patient. Multimodality imaging findings over 13 years- follow-up demostrated progressive wide spread skeletal and soft tissue abnormalities with permeative osteolysis, pathological fractures and severe sketal deformities. Unusual extensive osseous and soft tissue pneumatosis was illustrated on cross-sectional studies. The progressive nature of this form of gorham disease and the subsequent complications eventually culminated in patients's death.

    Hydrostatic reduction of intussusception under ultrasound guidance: an initial experience in a developing country
    (2007-07) Atalabi, O. M; Ogundoyin, O. O,; Ogunlana, D. I,; Onasanya, O. M.; Lawal, T. A.; Olarinoye, A. S.
    Background: Intussusception is one of the most common causes of acute intestinal obstruction in children. Hydrostatic reduction with barium enema is the widely accepted and preferred mode of treatment of uncomplicated intussuception. The aim of this study was to report our initial experience with hydrostatic reduction of intussusception. Patients and methods: We present our initial experience in which 8 patients had ultrasound guided hydrostatic reduction of intussusception over a period of 2 years. All patients that presented within 48hours of onset of symptoms were recruited into the study. Clinical diagnosis of intussusceptions was made in all of them while abdominal ultrasound was used to confirm the diagnosis. Results: Half of the patients presented after 24 hours of onset of symptoms. Five patients (62.5%) had a successful reduction of thier instussusception while was completed by surgery. There was only one (12.5%) recurrence and there was no peritonitis. Conclusion: Ultrasound guided hydrostatic reduction of intussusceptions in this environment is possible when patients present early with low risk of complication and low recurrence rate.

    Malignant haemangiopericytoma of the left thigh with metastases to the bones and lungs: A case report
    (2006) Atalabi, O. M; Ibinaiye, O. P.; Obajimi, M. O.; Ogunseyinde, O.; Akang, E. E. U.
    Haemangiopericytoma is an uncommon mesenchymal neoplasm. Haemangiopericytoma is believed to arise from the pericytes, contractile spindle cells that surround the capillaries and post-capillary venules. We present an unusal case of histologically confirmed malignant haemangiopericytoma of the thigh in a 70 year old male with metastasis to the lungs and left femoral bone.

    Clinicoradiologic and sonographic patterns of metastasis in hepatocellular carcinoma
    (2006) Otegbayo, J. A.; Atalabi, O. M.; Yakubu, A.
    Hepatocellular carcinoma(HCC) is usually diagnosed at an advanced stage, when little remedy could be offered. There is a need for relatively affordable, available and non- invasive tests for diagonsis, staging and detection of metastasis among individuals at risk. A clinical, chest radiographic (CXR) and abdominal ultrasonographic examination was carried out to detect and evaluate the pattern of metastasis among 53 untreated patients. One patients had clinical paraparesis with no outward evidence of metastasis. CXR revealed lund metastasis in 11(20.8%), with multifocal deposit in one. Two (3.8%) patients had perihilar lymphadenopathy and consolidation, respectively, while 18 (34%) patients had elevated right hemidiaphragm and four (7.5%) had pleural effusion. One right hemidiaphragm and four (7.5%) had pleural effusion. One had right basal pneumonitis, multiple cavitatory lesions in the lungs fields and soft-tissue wasting. No abnormality was seen in 17 (32.1%) cases. Abdominal ultrasonograph showed probe tenderness in 22(41.5%), hepatomegaly in 49(92.5%), with 33(62.3%) of these having nodularities of varying sizes. The spleen was enlarged in 10(18.9%) cases, with para-aortic lymphadenopathy. Portal hepatic lymphadenopathy was demostrated in two (3.8%) cases, while pleural effusion was detected in seven (13.2%). Metastasis is common in HCC at presentation, the lung is the commonest site of spread. Clinically visible metastasis appears uncommon in HCC.

    Renal Length, packed cell volume and biochemical parameters in subjects with chronic renal failure: a preliminary report
    (2006-12) Salako, B. L; Atalabi, O. M.; Amusat, A. M.; Adeniji-Sofoluwe.
    The constellation of laboratory and imaging findings that distinguish progressive chronic kidney disease (CKD) from acute renal failure are bilaterally small kidneys, elevated PTH, creatol, carbamylated haemoglobin levels, anaemia, hyperphosphataemia and hypocalcemia with elevated parathyroid hormone levels, and a urinary sediments that reveal proteinuria and broad casts. There has been a documented significant correlation between renal legth and GFR, but, the relationship between length and other ureamic and biochemical parameters is still unclear. This study assessed the relationship between renal length and serum biochemistry among chronic renal failure and patients seen at the University College Hospital, Ibadan. Patients withchronic renal failure who presented for the first time in predialytic phase were recruited.Renal ultrasound was used to assess renal length and based on this subjects were classified into those with shrunken kidneys and those with normal kidneys. Blood chemistry including PCV, serum urea and creatinine were performed. Creatinine clearance was calculated using Gault and Cockroft equation. The data were processed using the Statistical Package for the Social Sciences (SPSS) by comparing the means of biochemical parameters of the two groups. Twenty-one patients completed the study; there were 14males and 7 females with age range between 24-72 years, means age of 44.2 (15.4SD) years. Thriteen (61.9%) of them haad kidney length in the abnormal rannge (less than 9cm). No patients had enlarged kidneys. Majority of the patients in this study had bilateral shrunken kidneys but there were no correlations between kidney length and serum creatinine, urea, PCV and creatinine clearance.
