Anomalies and Curiosities of Medicine [166]
instances of four lobes in the right lung. Testut and Marcondes report a description of a lung with six lobes.
Anomalies of the Diaphragm.--Diemerbroeck is said to have dissected a human subject in whom the diaphragm and mediastinum were apparently missing, but such cases must be very rare, although we frequently find marked deficiency of this organ. Bouchand reports an instance of absence of the right half of the diaphragm in an infant born at term. Lawrence mentions congenital deficiency of the muscular fibers of the left half of the diaphragm with displacement of the stomach. The patient died of double pneumonia. Carruthers, McClintock, Polaillon, and van Geison also record instances of congenital deficiency of part of the diaphragm. Recently Dittel reported unilateral defect in the diaphragm of an infant that died soon after birth. The stomach, small intestines, and part of the large omentum lay in the left pleural cavity; both the phrenic nerves were normal. Many similar cases of diaphragmatic hernia have been observed. In such cases the opening may be large enough to allow a great part of the visceral constituents to pass into the thorax, sometimes seriously interfering with respiration and circulation by the pressure which ensues. Alderson reports a fatal case of diaphragmatic hernia with symptoms of pneumothorax. The stomach, spleen, omentum, and transverse colon were found lying in the left pleura. Berchon mentions double perforation of the diaphragm with hernia of the epiploon. The most extensive paper on this subject was contributed by Bodwitch, who, besides reporting an instance in the Massachusetts General Hospital, gives a numerical analysis of all the cases of this affection found recorded in the writings of medical authors between the years 1610 and 1846. Hillier speaks of an instance of congenital diaphragmatic hernia in which nearly all the small intestines and two-thirds of the large passed into the right side of the thorax. Macnab reports an instance in which three years after the cure of empyema the whole stomach constituted the hernia. Recently Joly described congenital hernia of the stomach in a man of thirty-seven, who died from collapse following lymphangitis, persistent vomiting, and diarrhea. At the postmortem there was found a defect in the diaphragm on the left side, permitting herniation of the stomach and first part of the duodenum into the left pleural cavity. There was no history of traumatism to account for strangulation. Longworth cites an instance of inversion of the diaphragm in a human subject. Bartholinus mentions coalition of the diaphragm and liver; and similar cases are spoken of by Morgagni and the Ephemerides. Hoffman describes diaphragmatic junction with the lung.
Anomalies of the Stomach.--The Ephemerides contains the account of a dissection in which the stomach was found wanting, and also speaks of two instances of duplex stomach. Bartholinus, Heister, Hufeland, Morgagni, Riolan, and Sandifort cite examples of duplex stomach. Bonet speaks of a case of vomiting which was caused by a double stomach. Struthers reports two cases in which there were two cavities to the stomach. Struthers also mentions that Morgagni, Home, Monro, Palmer, Larry, Blasius, Hufeland, and Walther also record instances in which there was contraction in the middle of the stomach, accounting for their instances of duplex stomach. Musser reports an instance of hour-glass contraction of the stomach. Hart dissected the stomach of a woman of thirty which resembled the stomach of a predaceous bird, with patches of tendon on its surface. The right extremity instead of continuously contracting ended in a culdesac one-half as large as the greater end of the stomach. The duodenum proceeded from the depression marking the lesser arch of the organ midway between the cardiac orifice and the right extremity. Crooks speaks of a case in which the stomach of an infant terminated in a culdesac.
Hernia of the stomach is not uncommon, especially in diaphragmatic or umbilical deficiency. There are many cases on record,
