ABSTRACT
This study presents a rare case of Rosai-Dorfman disease (RDD) with nasal and nasopharyngeal involvement, illustrating the complexities in diagnosing this enigmatic histiocytic disorder. RDD, characterized by massive, painless cervical lymphadenopathy, poses diagnostic challenges due to its diverse clinical presentations. In this case, a 38-year-old woman presented with a year-long history of neck swellings, nasal congestion, headaches, and sinusitis-like symptoms. Radiological imaging and histopathological examination revealed RDD involvement in the nasopharynx and paranasal sinuses. RDD diagnosis was confirmed through immunohistochemistry. The patient's unique symptoms emphasize the importance of considering RDD in the differential diagnosis of sinonasal masses with recurrent or unusual complaints. This case underscores the need for increased awareness, multidisciplinary management, and further research to enhance understanding and treatment of RDD, especially in extranodal presentations.
ABSTRACT
AVID (Asymmetric ventriculomegaly, interhemispheric cyst, and dysgenesis of corpus callosum) spectrum is a rare phenomenon as such in its whole and the defects are not exclusive to the condition. Each may occur in isolation or together and have characteristic clinical and imaging findings. The vast array of mimics coexisting with the condition makes it a harder diagnosis to make and requires a great length of experience and observation which may explain the limited recordings of AVID. Sonography and fetal magnetic resonance imaging goes a long way and provide accurate diagnosis ruling out the mimics and aiding in prenatal visualization of the defects. Accurate diagnosis aids in effective management and counseling regarding outcomes and the potential timeline of the severity of the symptoms. In its rarity, this case report of AVID is one of the first report of its kind reported from Nepal.
