Adrenal Myelolipoma, Cholelithiasis and Calcified Spleen: Retrospective Diagnosis of Sickle Cell Anemia Using a Novel Triad of Abdominal Imaging Findings
Sickle cell anemia is an inherited abnormality of the globin chain with very high prevalence in the Indian subcontinent. A significant proportion of these patients present late in life and are at a risk of complications like acute chest syndrome and painful episodes till a definitive diagnosis is reached and appropriate treatment is started . We report a novel triad of abdominal imaging findings which is not reported in literature until now and which may suggest a diagnosis of sickle cell anemia in retrospect. Patients with this triad of abdominal findings should be suspected to have an underlying hemoglobinopathy and should be referred for further hematological workup. Although in our case the patient was diagnosed to have sickle cell anemia depending on the abnormal morphology of red cells and hemoglobin electrophoresis, it should be remembered that this triad of findings may be seen in other hemoglobinopathies which induce a state of chronic anemia. Key words: sickle cell anemia, adrenal myelolipoma, gall stones, calcified spleen
Hirayama's disease: The importance of flexion magnetic resonance imaging
Hirayama′s disease is a form of juvenile muscular atrophy
affecting young individulas in their second to third decade. The
underlying pathogenetic mechanism is believed to be an imbalanced
growth between the individuals′ vertebral column and the spinal
canal contents, which causes abutment of the anterior spinal cord
against the vertebral column and detachment of the posterior dura,
leading to microcirculatory disturbances and ischemic changes in the
cord. This mechanism is exiquisitely demonstrated on magnetic resonance
imaging (MRI), but requires additional imaging, with the neck in the
flexed position. Neurphysiological imaging studies have provided
supporting evidence by demonstrating changes in the N13 potential, with
neck flexion. Nonetheless, few studies have also reported contradictory
findings with MRI and somatosensory evoked potentials, in Hirayamas
Disease. This condition is underdiagnosed because most clinicians are
not familiar with this disorder and do not request a flexion MRI. Early
recognition of this entity and differentiation from other causes of
focal cord atrophy is important, because limitation of neck flexion by
using a simple neck collar can prevent its further progression. We
report the classical MRI findings in a young patient with
Hirayama′s disease with neutral and flexion MRI
Imaging Findings of Disseminated Cysticercosis with Unusual Involvement of Spleen and Pancreas
In this study, we present a case of disseminated cysticercosis involving the brain, orbit, myocardium, muscle, subcutaneous tissues, pancreas, and spleen. Imaging studies are described with emphasis on pancreatic and splenic involvement which is a rare manifestation of a rather common disease and has been radiologically demonstrated only once previously. Although the involvement of the pancreas by parasites leading to pancreatitis has been described previously, in our case there was no clinical or biochemical evidence of pancreatitis due to infection by cysticerci
