Perianal Mucinous Adenocarcinoma (PMA) is a rare gastrointestinal malignancy, known to occur in patients with a long-standing history of recurrent perirectal abscesses or a chronic fistula. In this case report, we present a unique presentation of perianal mucinous adenocarcinoma, which began as a rectal abscess and progressed to a case of perianal mucinous adenocarcinoma, with a skip lesion present all the way up in the mid-rectal region. To the best of our knowledge, this is the first case in which PMA presented with skip lesions as opposed to a continuous lesion, and presented without a long standing history of fistulas and recurrent abscesses, but instead just a 4-day history of perianal burning, itching and tingling. The use of CT imaging, MRI’s and PET scans as diagnostic modalities for PMA are further elucidated in the report, along with a discussion of NCCN guidelines on using radiation therapy followed by an APR with inguinal node dissection for the management and treatment of PMA. Sharing this unique and atypical presentation of PMA with multimodality speciality groups and tumor boards helps in the development of various diagnostic and therapeutic approaches for PMA, as well as enhances our understanding of this rare malignant entity.

Background: Binasal Occlusion (BNO) is a clinical technique used by many neurorehabilitative optometrists in patients with mild traumatic brain injury (mTBI) and increased visual motion sensitivity (VMS) or visual vertigo. BNO is a technique in which partial occluders are added to the spectacle lenses to suppress the abnormal peripheral visual motion information. This technique helps in reducing VMS symptoms (i.e., nausea, dizziness, balance difficulty, visual confusion). Case Report: A 44-year-old AA female presented for a routine eye exam with a history of mTBI approximately 33 years ago. She was suffering from severe dizziness for the last two years that was adversely impacting her ADLs. The dizziness occurred in all body positions and all environments throughout the day. She was diagnosed with vestibular hypofunction and had undergone vestibular therapy but reported little improvement. Neurological exam revealed dizziness with both OKN drum and hand movement, especially in the left visual field. BNO technique resulted in immediate relief of her dizziness symptoms. Conclusion: To our knowledge, this is the first case that illustrates how the BNO technique in isolation can be beneficial for patients with mTBI and vestibular hypofunction. It demonstrates the success that BNO has in filtering abnormal peripheral visual motion in these patients.

COVID-19 Associated Mucormycosis (CAM) is an emerging infectious disease that has caused increased mortality & morbidity in India during this second wave of the pandemic. The country has reported more than 30,000 cases and over 2,000 deaths by Mucormycosis so far, according to sources from Union Health Ministry. CAM is now a notifiable disease. At our Tertiary care teaching hospital, which caters for COVID 19 management, we are reporting the first case of Rhino orbital CAM, which was caused by Rhizopus spp. Our patient had a history of contact with a suspected COVID 19 patient and was recently diagnosed with uncontrolled diabetes mellitus. A direct KOH microscopic examination of purulent material aspirated from the sinonasal polyp of the patient revealed fungal elements, and Rhizopus spp was isolated. Due to a shortage of Amphotericin B, the patient was referred to a government higher speciality centre for further management. The patient was followed up & was noted that he was treated with antifungal and discharged following recovery.

We report on the clinical history of a 49-year-old female with metastatic pancreatic cancer. She was initially treated with standard chemotherapy as per current guidelines. She was found to have both a BRAF and P53 mutation, and received dabrafenib and trametinib with deep responses, both radiographically and biochemically (CA19-9). Her response has been more clinically relevant than responses in previous case reports of patients with BRAF-positive pancreatic cancer treated with targeted therapy. To the best of our knowledge, this is the first case report showing a dramatic therapeutic response to combination therapy with dabrafenib and trametinib in metastatic pancreatic cancer.

A 9-year-old male, castrated Chihuahua was examined because of a 7-day history of intermittent vomiting. A mass in the small intestine was identified on abdominal radiography and ultrasonography. Laparotomy revealed a mass lesion originating in the ileum, and surgical resection was performed. The mass was histologically diagnosed as adenosquamous cell carcinoma. Chemotherapy with carboplatin was initiated, but the dog was suspected to have experienced recurrence 13 months after surgery and died 3 months later. To our knowledge, this is the first case report to describe the clinical course of adenosquamous cell carcinoma in the small intestine of a dog.

Abstract We report a patient who had pituitary adenoma and parasellar meningioma coincidentally, with neither irradiation nor a history of head injury. Preoperative computed tomographic (CT) scan had shown a large intrasellar mass with ringlike enhancement; in contact with this mass, another well-enhanced mass had been shown. Histopathologically, the intrasellar mass was diagnosed as chromophobic pituitary adenoma and the other mass as meningotheliomatous meningioma. We present clinical, radiological, and histopathological findings and discuss previously reported cases of coincidental pituitary adenoma and meningioma without irradiation. This is the first case report since the advent of CT that pituitary adenoma and parasellar meningioma in contact with each other could be clearly demonstrated by CT.

Abstract BACKGROUND AND IMPORTANCE: Vein of Galen aneurysmal malformations (VGAMs) arise from persistent arteriovenous shunting from primitive choroidal vessels into the median prosencephalic vein of Markowski, the embryonic precursor of the vein of Galen. VGAMs rarely present past infancy, and their natural history in adults is unknown. We report the first case of a familial-associated VGAM in an asymptomatic adult female patient. The clinical features of this case are presented alongside a systematic review of the literature on adult VGAM cases to assess the natural history, clinical management, and genetic basis of this rare neurovascular lesion. CLINICAL PRESENTATION: A previously healthy 44-year-old woman with a family history of a VGAM in a stillborn presented with an 8-week onset of dizziness and vertigo that spontaneously resolved. Time-resolved magnetic resonance angiography identified a choroidal VGAM. No intervention was undertaken at this time because of the patient's asymptomatic status after 9 months of follow-up. CONCLUSION: Based on our review of the literature, this is the first case report of a familial-associated VGAM in an adult patient and suggests that VGAM development can be genetically linked. Of 15 adult VGAM cases previously reported, all patients were either symptomatic or treated, thus precluding determination of VGAM natural history in adults. Patient outcomes correlated with the severity of presenting symptoms, which ranged from asymptomatic to immediately life-threatening. We hypothesize that self-selection may render VGAMs to be more benign for them to persist past childhood. Further investigation of the molecular biology underlying VGAM development is warranted.

BACKGROUND: Cranioplasty is aimed to restore the structure and function of the lost portion of the skull defect. Many materials can be used for cranioplasty, such as the bones of the patient (autograft), the bones of other patients (allograft), bones of animals (xenograft), or synthetic materials such as acrylic or titanium mesh. These materials are quite expensive and sometimes require complex processes. Manual shaping of material for cranioplasty is also quite time-consuming and prone to cause esthetic dissatisfaction. The author will discuss the case of using polylactic acid (PLA) implant with 3-dimensional (3D) printing customization as a cheap and accurate cosmetic solution for cranioplasty procedures. CASE REPORT: We report 2 cases of skull defect underwent cranioplasty. The first case, female, 20-year-old, had a history of severe traumatic brain injury (TBI) and epidural hematoma. She underwent decompression craniotomy on the left frontotemporoparietal region of her skull. The second case, male, 46-year-old, had a history of spontaneous intracerebral hemorrhage due to arteriovenous malformation (AVM). He underwent decompression craniotomy on the right frontotemporoparietal region of her skull. Both the data of computerized tomography (CT) scan were reconstructed to get 3D model of skull defect. Prosthesis was made by 3D printer accordingly using PLA as material. There was no complication reported postoperatively and cosmetic satisfaction was obtained on both cases. CONCLUSION: The use of PLA implant with 3D printing customization was proved to be cost-effective and good cosmetic satisfaction with no complication reported following cranioplasty procedure.

Introduction Alpha (⍺)-gal syndrome (AGS) is an immunoglobulin E (IgE) antibody response against the glycoprotein carbohydrate galactose-⍺-1,3-galactose-β-1-(3)4-N-acetylglucosamine-R (Gal⍺-1,3Galβ1-(3)4GlcNAc-R or ⍺-gal) that is present in Ixodida (tick) saliva and noncatarrhine mammals as well as cetuximab, antivenom, and the zoster vaccine. The most frequently observed anaphylactic reactions in AGS are observed after beef, pork, lamb, and deer meat consumption. We present the first case of anaphylaxis to buffalo meat. Case Report A 55-year-old man presented with a history of recurrent urticaria that only developed approximately 7 hours after buffalo consumption. The patient denied history of Ixodidae bites but admitted to frequent hiking outdoors. Anti-⍺-1,3-gal IgE was positive (30.80 kU/L). The patient was advised to strictly avoid red meat. Discussion The prevalence of AGS has been increased in all continents in the past decade, and several Ixodidae species have been associated with this hypersensitivity. The list of IgE-mediated reactions to various types of meat has expanded to kangaroo, whale, seal, and crocodile, although these have not been associated with AGS. van Nunen only cautioned against consumption of exotic meats, such as buffalo, but no published case report describes AGS associated with anaphylaxis to this type of meat. Conclusion AGS is a mammalian meat allergy that has been increasingly prevalent worldwide, especially in Ixodidae endemic regions of Australia and the United States. Multiple AGS case reports published in the past decade demonstrate rapidly increasing understanding of underlying mechanisms provoking ongoing sensitization to help devise management strategies and dietary information. We offer the first case report of delayed anaphylaxis to buffalo meat.

Background: The ectopic posterior pituitary (EPP) is a rare condition characterized by the ectopic location of the posterior pituitary lobe associated with varying degrees of stalk anomalies. The arachnoid cysts (AC) are benign lesions of the arachnoid, which account for 1% of all intracranial space-occupying lesions. Sellar/suprasellar ACs account for approximately 1% of all ACs. This is the first case of coexistence EPP with sellar/suprasellar AC. Case Report: A 67-year-old woman presented with 6 months history of fatigue. Her medical history was positive for irregular menstruation. Her endocrine examinations indicated low free thyroxine level with low TSH level, low oestradiol with low gonadotrophin level, slightly elevated prolactin level. Her Insulin-like growth factor-1 was below the normal levels. Dynamic contrast hypophysis MRI revealed a sellar cystic lesion with a dimension of 18 × 14 × 14 mm, extending from the suprasellar cistern, traversing the diaphragma sellae and reaching the level of the floor of the 3rd ventricle, consistent with sellar/suprasellar AC. There was no wall enhancement. The optic chiasm was compressed. The precontrast T1-weighted magnetic resonance images did not demonstrate the characteristic bright spot of posterior pituitary within the sella, which was higher in position, in the region of the median eminence. The pituitary stalk was not present. Conclusion: Although speculative, we have a hypothesis to explain how the EPP and sellar/- suprasellar AC coexist in this patient. Due to the absence of stalk, CSF may enter the sella tursica from the central aperture of the diaphragma sellae through which normally the stalk passes.

Acute subdural hemorrhage following the trauma of a difficult birth is a recognized cause of an increase in head circumference and anemia soon after birth.1 Although major subdural hemorrhages occurring in the fetus before the onset of labor are relatively rare, in most reported cases these also have been traumatic, the result of motor vehicle accidents or assaults.2-7 With few exceptions, there have been associated uteroplacental or other fetal injuries. In 1977, MacDonald et al8 believed they were making the first case report of an infant born with hydrocephalus and anemia due to bilateral subdural hematomas in which there was no history of maternal trauma.
