Cases of disseminated nontuberculous mycobacterial (NTM) infection are difficult to treat. We encountered an elderly man with disseminated Mycobacterium chelonae infection. The clinical evaluation and treatment of patients with this type of systemic infection pose unique challenges. Disseminated NTM infection with bone involvement often requires surgical intervention in addition to antimicrobial therapy.

ABSTRACT We present a case of chronic non-communicating hydrocephalus (NCH) in a US military recruit. Non-communicating hydrocephalus is a pathologic obstruction of cerebrospinal fluid (CSF) resulting in enlargement of the ventricles and elevated intracranial pressure. The patient is an 18-year-old male recruit who was evaluated in the Naval Medical Center emergency room for left hip pain and incidentally was found to have profound ventriculomegaly on head imaging. The diagnosis and evaluation of hydrocephalus is greatly dependent on clinical history and supported by radiographic imaging. Based on these factors, one can determine if the hydrocephalus is either acute or chronic and communicating or non-communicating.

Mediastinal lesions occur in a wide variety of clinical conditions. Metastatic granulosa cell tumour (GCT) in the mediastinum is a rare occurrence. We report a case of a woman who had a metastatic (GCT) in her mediastinum 40 years after treatment of the initial neoplasm. Surgical resection of the mediastinal mass revealed a low‐grade epithelioid neoplasm with coffee bean‐shaped nuclei and immunohistochemical stains that were consistent with metastatic GCT.
