Bilateral Multifocal Hamartoma of the Chest Wall in an Infant

Background: Hamartoma of the thoracic wall is a rare benign tumor that occurs in infancy and can be mistaken for a malignancy due to its clinical and imaging features. Hamartomas are extrapleural soft tissue lesions that cause rib expansion and destruction and appear on imaging as cystic areas with fluid levels and calcification. They can cause scoliosis, pressure on the neighboring lung parenchyma and mediastinal displacement. While conservative treatment is recommended in asymptomatic cases, growing lesions require surgical excision

A late diagnosis of Pott's disease in an adolescent with psoas abscess

Psoas abscess is classified as primary or secondary according to presence or absence of the underlying focus of infection. Secondary psoas abscesses are much more common and tuberculosis of the spine (Pott's disease) is one of the leading predisposing diseases. Here we report a 16-year-old male presented with flank pain and abdominal distention, followed by spontaneous purulent drainage from lower back and lower abdomen. Eventually a painful swelling appeared below the right knee about one year after the appearance of the first symptoms. He was diagnosed as Pott's disease and secondary psoas abscess based on specific culture of draining pus, which yielded Mycobacterium tuberculosis and spinal magnetic resonance imaging (MRI) findings. Psoas abscess due to Pott's disease may show a nonspecific and chronic clinical course resulting in a late diagnosis and increased morbidity, as in the reported case. Clinicians in the endemic countries should be aware of this rare and challenging clinical entity

Simultaneous Presentation of Wilms' Tumor and Contralateral Ganglioneuroma in a Child: Case Report and Literature Review

We demonstrate a 4-year-old girl who presented with progressive, asymmetrical, firm abdominal distention and was diagnosed with synchronous Wilms' tumor and left para-aortic ganglioneuroma (GN). Although synchronous tumors in the pediatric population are commonly associated with malignancy-predisposing syndromes, the patient in question was found to be otherwise healthy and had no clinical evidence nor family history of a syndrome. This case is the second one in the literature diagnosed with synchronous presentation of Wilms' tumor and GN in a previously healthy child. In addition, a GN foci presumed to be a previous metastasis of a neurogenic tumor that subsequently matured to GN was depicted within a left para-aortic lymph node. We aimed to emphasize an extremely rare synchronous occurrence of these embryonal tumors, increase the awareness of physicians, and discuss the radiologic differential diagnosis and management
