Introduction. Agenesis of the right lobe of the liver is a rare finding and was defined as the absence of liver tissue on the right side, with preservation of the middle hepatic vein, without previous disease or surgery. It is usually an incident finding reveled by imaging exams or during abdominal surgery.Case Report. A 32-year-old male patient was admitted to the hospital for abdominal discomfort and loss of appetite. Imaging studies revealed the absence of the right hepatic lobe and hypertrophied left hepatic segments.Discussion. Anomalies of hepatic morphology are rare and correspond to developmental defects during embryogenesis, are a rare diagnosis, and are generally diagnosed incidentally based on imaging. Agenesis or hypoplasia of the right lobe may predispose the patient to the development of portal hypertension and esophageal varices. Surgical knowledge of such anatomical agenesis is necessary for surgical planning, for the appropriate identification of intraoperative surgical findings, and for the design of the postoperative approach to therapy.Conclusion. Agenesis of the right hepatic lobe is a rare condition. We want to highlight the importance of understanding the condition. Surgeons must recognize the entity in order to deal appropriately with the findings.

Introduction. The difficulty and challenge of recovering a right lobe graft without MHV drainage is reconstructing the outflow tract of the hepatic veins. With the inclusion or the reconstruction of the MHV, early graft function is satisfactory. The inclusion of the MHV or not in the donor’s right lobectomy should be based on sound criteria to provide adequate functional liver mass for recipient, while keeping risk to donor to the minimum. Objective. Reviewing the results of a policy for right lobe grafts transplant without MHV and analyzing methods of venous reconstruction related to outcome. Materials and Methods. We have two groups Group A (with more than one HV anast.) (n=16) and Group B (single HV anast.) (n=24). Both groups were compared regarding indications for reconstruction, complications, and operative details and outcomes, besides describing different modalities used for venous reconstruction. Results. Significant increase in operative details time in Group A. When comparison came to complications and outcomes in terms of laboratory findings and overall hospital stay, there were no significant differences. Three-month and one-year survival were better in Group A. Conclusion. Adult LDLT is safely achieved with better outcome to recipients and donors by recovering the right lobe without MHV, provided that significant MHV tributaries (segments V, VIII more than 5 mm) are reconstructed, and any accessory considerable inferior right hepatic veins (IRHVs) or superficial RHVs are anastomosed.

Riedel's lobe (ectopic lobe), also known as the accessory hepatic lobe, consists of an anatomical variation characterized by a tongue-shaped protrusion on the visceral surface of the liver right lobe, fixed by a pedicle. This variant draws attention in the clinical practice, as it can be mistaken for a tumor due to its elongated aspect. The aim of this research was to conduct a study on the anatomical characteristics and clinical and functional peculiarities of the accessory hepatic lobe. The paper is based on a integrative review and observational study on a cadaveric specimen. A cadaver with anatomical variation was used. Data were collected in PubMed, Scielo, and VHL. 257 articles were found in the databases, but only 13 were used for research. In careful review, two rare cases of the accessory lobe in the left lobe of the liver, hypoplastic left lobes, and agenesis of the right hepatic lobe, and often the clinical picture without changes in signs and symptoms were found. These morphological abnormalities' clinical impact is limited in the absence of underlying liver disease, cirrhosis, or known cancer. In case of complications or after the diagnosis of pedunculated tumors in the liver, laparoscopy is well indicated for removing these lobes or tumors.

Mycobacterium tuberculosis (MTB) is an aerobic bacillus responsible for tuberculous infection. The the thyroid gland being affected by MTB is a rare condition. A 71-year-old woman had 6 months of slight cervical discomfort. Her neck ultrasound showed, at the right lobe of the thyroid, a dominant heterogeneous nodule of 18 mm and homolateral lymph nodes with suspicious ultrasonographic features. The patient underwent fine-needle aspiration, the results of which were non-diagnostic (thyroid nodule) and reactive pattern (lymph node). A total thyroidectomy was performed and a lymph node was sampled for extemporaneous examination. Surprisingly, necrotising granulomas were documented. The diagnosis was definitely established by a positive culture of the lymph node tissue and molecular detection of MTB. Pulmonary involvement was excluded and she was started on antituberculous agents. In the absence of systemic, specific complaints or history of exposition, histopathology and culture of MTB remain a key step for the diagnosis.

Liver abscesses are an uncommon disease that can present with vague symptoms. <em>Fusobacterium necrophorum</em> causing liver abscesses is a rare condition and only a few cases have been reported. An 88-year-old female presented to her primary care physician with one week of fevers, night sweats, chills, fatigue and vague right upper quadrant abdominal pain. She denied nausea, vomiting, constipation, diarrhea and unintentional weight loss. A computed tomography scan of the abdomen showed two liver abscesses in the right lobe as well as extensive diverticulosis. Percutaneous drainage was performed and draining catheters were placed in the abscesses. Culture of the abscess fluid grew <em>Fusobacterium necrophorum</em>. She was treated with ceftriaxone and metronidazole as per sensitivities. Rare cases of <em>F. necrophorum</em> hepatic abscesses have been published. The source of infection described in reported cases included hematogenous spread from dental caries/peritonsillar abscess and those involving the gastrointestinal tract resulting from inflammation of the bowel wall or from inflamed diverticuli via the portal circulation. In one study, thirteen cases of liver abscess due to <em>F. necrophorum</em> were studied, and two of these cases had diverticular disease without inflammation.

A newborn girl was referred to the otolaryngology service after prenatal imaging showed a right mandibular mass. Physical examination revealed a 1–2 cm mass along the right mandible with the appearance of a vestigial oral cavity. Tissue resembling the vermillion and primitive tongue appeared innervated and moved in conjunction with oral movements. MRI and CT of the mandible after birth confirmed a partially ossified soft tissue mass of the right mandibular body, containing unerupted teeth. She was taken to the operating room at 6 months of age for mass excision and reconstruction. Postoperatively, she healed well and was feeding without difficulty. Craniofacial duplication, including duplication of stomatodeal structures or diprosopus, is a rare condition with a variety of phenotypes. In the case of suspected craniofacial duplication, associated syndromes should be ruled out and appropriate imaging employed to determine the extent of involvement of adjacent structures, which will ultimately guide surgical planning.

Marked Atrophy

A 22 year-old horse developed cholelithiasis with marked atrophy of the right lateral hepatic lobe. The horse had a history of intermittent colic since three years of age, and one of the first episodes of colic was associated with icterus. The size of the right lateral hepatic lobe was extremely reduced. There was a large choledocholith in the common hepatic duct, and several hepatoliths and choleliths in the intra- and extra-hepatic billiary ducts. Microscopically, there was severe atrophy of the right lobe with diffuse proliferation of connective tissue and billiary ducts. The left lateral lobe had peri-portal fibrosis with proliferation of billiary ducts, and billiary stasis. Chemical analysis of the calculi detected amorphous and triple phosphate, bilirubin, calcium, and iron.
