Brain Magnetic Resonance Imaging Findings in Patients with Developmental Delay in Addis Ababa, Ethiopia.

Background: Developmental delay is a major health problem throughout the world causing significant individual disability. Even though physical examination and patient history are the most important and basic evaluations of patients with developmental delay, additional investigations are usually required in supporting or reaching a diagnosis among which is neuroimaging. This study aims to assess brain Magnetic resonance imaging (MRI) patterns in patients presented with developmental delay. Method: A retrospective analysis of 164 patients who had undergone brain Magnetic Resonance Imaging (MRI) evaluation for the developmental delay was done. The study was conducted between March to November 2021 G.C at Tikur Anbessa Specialized Hospital (TASH). The patients' clinical history and magnetic resonance imaging reports were reviewed from their medical records. All patients with developmental delay who had brain MRI evaluation at TASH and at one private diagnostic center in Addis Ababa were included in the study. Results: A total of 164 patients were included in this study of which 95(57.9%) were male and 69(42.1%) female patients were seen. A total of 120 patients (73.2%) showed abnormal brain MRI studies. Previous neurovascular insults were the most common abnormalities seen in 75(45.7%) patients followed by imaging findings of congenital and developmental abnormalities seen in 20(12.2%) patients. Conclusion: Brain MRI is an important input in the evaluation of patients with developmental delay. It can give evidence for the cause of developmental delay, especially in the diagnosis of perinatal/hypoxic-ischemic insults, and congenital and developmental malformations.

Imaging Findings of Concomitant Pulmonary and Central Nervous System Sarcoidosis: A Case Report.

Background: Sarcoidosis is a multisystem idiopathic granulomatous disorder characterized by the development of noncaseating infiltrative granulomas in various body organs. The central nervous system (CNS) is one of the sites to be affected by sarcoidosis. We present a case of sarcoidosis with concomitant involvement of lung and CNS with emphasis on neuroimaging findings. Case: A 45-year-old Ethiopian male patient was sent to our radiology department at Tikur Anbessa Specialized Hospital for chest computed tomography (CT) and brain Magnetic resonance imaging (MRI) evaluation for an indication of panhypopituitarism, nasal congestion, and decreased vision. The chest CT reveals the perilymphatic distribution of multiple soft tissue attenuating pulmonary nodules which is a pattern seen in sarcoidosis. The brain MRI also revealed thickening and gadolinium enhancement of hypothalamus/optic chiasm which is also a common site of involvement in neurosarcoidosis. The nasal biopsy finding of granulomatous inflammation with the above imaging findings supports the diagnosis of sarcoidosis. Conclusion: As sarcoidosis is a systemic disease that can affect any organ in the body, multimodality imaging is important in the diagnosis of sarcoidosis. Brain MRI with gadolinium contrast is a preferred imaging modality that can assess different patterns and areas of CNS involvement in sarcoidosis.

A Retrospective Analysis on Cervical Spine Magnetic Resonance Imaging Findings in Patients with Neck Pain in a Tertiary Hospital, Addis Ababa, Ethiopia.

BACKGROUND: Neck pain is a common health problem throughout the world causing significant individual disability and economic burden on health care facility. Many factors are mentioned as a cause or association in relation to neck pain, of which degenerative and posttraumatic cause are the main ones. The aim of this study is to assess cervical spine Magnetic Resonance Imaging (MRI) patterns in patients presented with neck pain. METHODS: A retrospective analysis of 160 patients who had cervical spine Magnetic Resonance Imaging (MRI) for evaluation of a neck pain was done. The study was conducted between February to August 2018 at Tikur Anbessa Specialized Hospital. The patients' clinical history and magnetic resonance imaging reports were reviewed from their medical records. All patients who have cervical spine Magnetic Resonance Imaging (MRI) for a neck pain were included in the study. Those patients with acute traumatic neck pain were excluded. RESULTS: From a total of 160 patients, 71(44.4%) were males and 89(55.6%) were females. Degenerative cervical spine findings such as intervertebral disc degenerations were seen in 127(79.4%) patients. Non-degenerative imaging findings such as neoplasm and infection were seen in 10(6.3%) patients only. The MRI was normal in 23(14.4%) of them. CONCLUSION: The most common cause of neck pain from this study is degenerative changes of the cervical spine, which was predominant in the older age groups. Non-degenerative causes such as neoplasm and infection were less common findings.
