Pneumoperitoneum is most commonly the result of a visceral perforation and usually presents with signs of acute peritonitis requiring an urgent surgical intervention. Non-surgical spontaneous pneumoperitoneum (not associated with a perforated viscus) is an uncommon entity related to intrathoracic, intra-abdominal, gynecologic, iatrogenic and other miscellaneous causes, and is usually managed conservatively. Idiopathic spontaneous pneumoperitoneum is an even more rare condition from which both perforation of an intra-abdominal viscus and other known causes of free intraperitoneal gas have been excluded. ⋯ A thorough history and physical examination combined with the appropriate laboratory tests and radiologic techniques are useful tools in identifying patients with non-surgical pneumoperitoneum and avoiding unnecessary operations.

Bronchial stump aspergillosis is a rare entity characterized by cough and hemoptysis. ⋯ Bronchial stump aspergillosis is an unusual complication after pulmonary resection. Clinicians should be aware of it when a local recurrence of cancer around the bronchial stump is suspected based on a positive positron emission tomography and computed tomography finding.

Encephalopathy is a rare disease caused by adverse effects of antibiotic drugs such as metronidazole. The incidence of metronidazole-induced encephalopathy is unknown, although several previous studies have addressed metronidazole neurotoxicity. Here, we report the case of a patient with reversible cerebellar dysfunction on magnetic resonance imaging, induced by prolonged administration of metronidazole for the treatment of infectious colitis. ⋯ Metronidazole may produce neurologic side effects such as cerebellar syndrome, and encephalopathy in rare cases. We show that metronidazole-induced encephalopathy can be reversed after cessation of the drug. Consequently, careful consideration should be given to patients presenting with complaints of neurologic disorder after the initiation of metronidazole therapy.
