The aim of this study was to report the response to a bacterial intrauterine infection in a calf. A stillborn calf, dam’s blood and amniotic fluid were submitted for examination. Necropsy of the calf was performed and IgG1, IgG2, IgM, IL-6 in the calf’s serum, Il-6 in the dam’s serum, and amniotic fluid were estimated. During necropsy, fluid in pleural and peritoneal cavities stained with haemoglobin and diagonal fissures in the aortic arch endothelium were found.Salmonella entericaserovar Stanley was isolated from the spleen, lungs and abomasal fluid.Histopathological examination revealed: inflammatory infiltration and haemorrhages in lungs and small perivascular haemorrhages in the frontal cortex and near the lateral ventricles of the white matter, focal gliosis in the frontal cortex, and neuronal atrophy of the dentate gyrus with diffuse glial cells proliferation in the brain. The concentration of IgG1in the calf’s serum was increased and IL-6 was detected in both the dam’s blood and amniotic fluid. Necropsy, bacterial culture and immunological findings in the stillborn calf confirmed the intrauterine infectionwithSalmonellaStanley as the cause of death. Meanwhile, neonatal diarrhoea (incidence 46%) with high mortality (54%) occurred on the same farm. From diarrhoeic calves,SalmonellaTyphimurium andS.Enteritidis were isolated. Based on available literature this is the first evidence ofSalmonella entericaserovar Stanley isolation from a stillborn calf.

A case of pyogranulomatous micotic encephalitis in a one-year old, female, Fila Brasileiro dog is reported. Gross examination of the cerebrum revealed a softened haemorrhagic area in the right frontal cortex and on the cut surface of the left hemisphere, which affected the white matter and deep cortical areas. The diagnosis of multifocal mycotic pyogranulomatous encephalitis was obtained by the histopathological examination, which showed the presence of macrophages, giant cells, haemorrhage and brownish septate hyphae diffusely distributed within the tissue and invading vessel lumina. Identification of amastigotes forms in popliteus lymphonode imprint confirmed infection by Leishmania sp. Mycotic infection in the brain of this dog was related to a concurrent leishmaniosis, an immunosuppressive disease.

BACKGROUND: Adenocarcinoma (ADC) of the lung is the most common subtype of non-small cell lung cancer (NSCLC), occurring in ~40% of all patients with significantly higher incidence of brain metastasis compared with other subtypes of NSCLC. Among the five subtypes ADC of the lung, micropapillary predominant ADC may be more likely to metastasize. There are almost no reports of micropapillary ADC of the lung initially discovered to metastasis into the same site in the brain that has been previously operated. CASE REPORT: We reported a 54-year-old woman who was referred to ICU of Dr. Hasan Sadikin Hospital, Bandung, due to a decreased of consciousness. Head computed tomography scan revealed multiple isohypodense lesions in the right frontal with brain edema. She had craniotomy total tumor removal 8 months earlier and diagnosed as brain metastasis due to micropapillary ADC of the lung. She refused to receive chemoradiotherapy. At the operation site, multilobulated lesions were found, and hence, she was operated for the 2nd time at the same site with the first one, exhibited the same histology. Immunohistological shown positive results for thyroid transcription factor (TTF)-1 and cytokeratin (CK)-7; negative for CK-20, led to a diagnosis of micropapillary ADC of the lung. CONCLUSION: Herein, we reported our experience regarding a case of micropapillary ADC of the lung, considered as poorly differentiated ADC and associated with a high-grade lesion that metastasized to the same site that had been previously operated, twice. A definitive diagnosis was possible only through a histopathological examination along with a good communication between the surgeon and the pathologist.

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.

Moyamoya is an uncommon disease that presents with stenoocclusion of the major vasculature at the base of the brain and associated collateral vessel formation. Many pediatric patients with moyamoya present with transient ischemic attacks or complete occlusions. The authors report the case of a 9-year-old girl who presented with posterior fossa hemorrhage and was treated with an emergency suboccipital craniotomy for evacuation. After emergency surgery, an angiogram was performed, and the patient was diagnosed with moyamoya disease. Six months later, the patient was treated for moyamoya using direct and indirect revascularization; after surgery there was excellent vascularization in both regions of the bypass and no further progression of moyamoya changes. This case illustrates a rare example of intracerebral hemorrhage associated with moyamoya changes in the posterior vascularization in a pediatric patient and subsequent use of direct and indirect revascularization to reduce the risk of future hemorrhage and moyamoya progression.

Diffuse Leptomeningeal Glioneuronal Tumor

Abstract Background Diffuse leptomeningeal glioneuronal tumor (DLGNT) has been recently described in the literature. The complete neuroimaging spectrum and histopathological characteristics of this entity are yet to be elucidated. In an endemic region, diffuse leptomeningeal enhancement on neuroimaging with associated communicating hydrocephalus is usually suggestive of infective meningitis and the patients are started on empirical anti-microbial therapy. However, it is important to consider other differential diagnosis of leptomeningeal enhancement in such cases, particularly if the clinical condition does not improve on anti-microbial therapy. An early diagnosis of a neoplastic etiology may be of particular importance as the treatment regimens vary considerably depending on the underlying disease condition. Case presentation In this case report, we describe a case of DLGNT with high-grade histopathological features which was initially managed as tubercular meningitis based on the initial neuroimaging findings. Due to worsening of the clinical course and subsequent imaging findings at follow-up, a diagnosis of DLGNT was considered and subsequently proven to be DLGNT with features of anaplasia on histopathological examination of leptomeningeal biopsy specimen. Conclusion This case highlights the importance of recognizing certain subtle finding on MRI which may help in an early diagnosis of DLGNT which is crucial for appropriate treatment.

Abstract Background Heterotopic ossification (HO) is the formation of osseous tissue outside the skeleton. HO in malignant tumors of the digestive tract is extremely rare, as is ossification in metastatic lesions from HO-negative digestive tract tumors. Regarding the pathogenesis of HO, two theories have been proposed. The first is that the osteoblastic metaplasia of tumor cells (driven by the epithelial-mesenchymal transition, EMT) results in HO, and the second is that factors secreted by cancer cells lead to the metaplasia of stromal pluripotent cells into osteoblasts. However, the osteogenic mechanisms remain unclear. Case presentation An 83-year-old Japanese woman underwent low anterior rectal resection for rectal cancer before presentation at our institution, in June 2018. The final diagnosis was stage IIB rectal adenocarcinoma (T4aN0M0). Histological examination did not reveal HO in the primary tumor. Thirteen months after the operation, a solitary metastatic lesion in the brain 20 mm in size and a solitary metastatic lesion in a right axillary lymph node 20 mm in size were diagnosed. The patient was treated with gamma-knife therapy for the brain metastasis. One month later, she was referred to our institution. She underwent lymph node resection. Histological examination revealed that most portions of the affected lymph node were occupied by metastatic tumor cells and that central necrosis and four small ossified lesions without an osteoblast-like cell rim were present in the peripheral region. Immunohistochemical analysis showed tumor cells positive for BMP-2, osteonectin, osteocalcin, AE1/AE3, TGF-β1, Gli2, Smad2/3, and CDX2 and negative for nestin, CD56, and CK7. Conclusion This is the first English case report of HO in a metachronous metastatic lymph node after the curative resection of HO-negative rectal cancer. Unlike HO lesions in past reports, the HO lesion did not show peripheral osteoblast-like cells, and the immunohistochemical findings indicated that the present case resulted from the EMT.
