What pulmonologists need to know about extrapulmonary tuberculosis.

Extrapulmonary tuberculosis (EPT) can affect all organs. Its diagnosis is often challenging, especially when the lung is not involved. Some EPT locations, such as when the central nervous system is involved, are a medical emergency, and some have implications for treatment options and length.

Perilymphatic fistula after underwater diving: a series of 11 cases.

Introduction: Onset of cochleovestibular symptoms (hearing loss, dizziness or instability, tinnitus) after a dive (scuba or breath-hold diving) warrants emergency transfer to an otology department. One priority is to investigate the possibility of the development of decompression sickness with a view to hyperbaric oxygen treatment of bubble-induced inner-ear damage. If this injury is ruled out, inner-ear barotrauma should be considered together with its underlying specific injury pattern, perilymphatic fistula.

A rare presentation of metastatic renal clear cell carcinoma to the tongue seen on FDG PET.

Renal clear cell carcinoma has a great metastatic potential, with possibly uncommon secondary lesions, notably in the head and neck region. The role of F-18 fluorodeoxyglucose positron emission tomography (F-18 FDG PET) in the staging or follow-up of urological malignancies is still not clearly defined. We report a case of metastatic renal cell carcinoma involving the tongue and a cervical lymph node, 3 years after initial nephrectomy.
